Main features

The GLOCK Safe Action® self-loading pistol, with its no-compromise design, combines all the features demanded of the modern handgun of today – and tomorrow.

• Extremely low overall weight
• High magazine capacity
• An outstanding performance combining advanced methods of manufacturing with top-quality materials.
• GLOCK pistols have passed the most stringent military and industry test and are known worldwide for their state-of-the-art technology, durability, reliability and accuracy.
• The photographs and drawings in this manual reference the GLOCK 17 Gen5 pistol. Unless otherwise indicated, they are equally applicable to other models and previous versions of the GLOCK pistol.
• FRAME: The frame (17) is made of polymer with hardened steel guides. It features an ideal grip angle and low weight.
• The slide stop lever (27) and the magazine catch (19) are easily operated with the shooting hand. GLOCK Gen4, Gen5 and Crossover pistols feature interchangeable backstraps (17a/b and 17c/d) to vary the circumference of the frame and an extended magazine catch that is reversible for right or left hand use.
• ( Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).
• SAFE ACTION® TRIGGER SYSTEM: GLOCK’s revolutionary Safe Action® trigger system provides a consistent trigger pull from the first to the last round.
• The three automatic independently operating mechanical safeties are built into the fire control system of the pistol. All three safeties disengage sequentially as the trigger is pulled and automatically reengage when the trigger is released.
• This safe, simple and fast system allows the user to concentrate fully on tactical tasks, particularly while under stress.
• It is safe if dropped and functional at temperatures from -40° to 122° Fahrenheit / -40° to 50° Celsius.
• WARNING! If the trigger is in the forward position, your GLOCK pistol may be loaded.

1. Trigger Safety: Trigger safety is a lever incorporated into the trigger (26). When the trigger safety is in the forward position it blocks the trigger from moving rearward. The trigger safety and the trigger must be fully depressed at the same time to fire the pistol. If the trigger safety is not depressed, the trigger will not move rearward and allow the pistol to fire. The trigger safety is designed to protect against firing if the pistol is dropped or the trigger is subjected to lateral pressure.
2. Firing Pin Safety: The firing pin safety (8) mechanically blocks the firing pin (4) from moving forward in the ready-to-fire condition. As the trigger is pulled rearward the trigger bar pushes the firing pin safety up and frees the firing pin channel. If the user decides not to fire and releases the trigger, the firing pin safety automatically reengages.
3. Drop-Safety: The trigger bar rests on the safety ramp within the trigger mechanism housing. The trigger bar engages the rear portion of the firing pin (4) and prevents the firing pin from moving forward. As the trigger (26) is pulled rearward the trigger bar lowers down the safety ramp and allows the release of the firing pin. After firing, the trigger bar moves upward and reengages the firing pin.
   • WARNING! Your GLOCK pistol does not have a conventional manual safety and it will fire if the trigger is pulled when there is a round in the chamber.
   • WARNING! Although GLOCK pistols have several internal design features and mechanical safeties designed to prevent an unintentional discharge if the pistol is dropped or hit, the proper and safe function of your GLOCK pistol depends on it being used for its intended purposes and not being altered or modified. Like any other mechanical device, if your GLOCK pistol is subjected to unusual and extreme forces a part failure can occur. Therefore, safe firearm handling practices and the instructions and safety warnings in this manual must always be followed to minimize the risk of a negligent discharge.
   • WARNING! In case any of your GLOCK pistol’s safeties prove to be ineffective for any reason, the possibility of an unintentional discharge exists. If so, your GLOCK pistol should be immediately unloaded and not be used again until it has been examined by a GLOCK-Certified Armorer.
   • SLIDE: The advanced surface treatment of slide (1) results in optimal hardness by considerably reducing wear and tear and it makes it corrosion-resistant, even when operating in saltwater conditions. The matte black surface minimizes light reflection – an advantage in tactical circumstances.
   • BARREL: The barrel (2) is mechanically locked and cold-hammer forged. It also has the same advanced surface treatment as the slide. The rounded (hexagonal or octagonal) interior profile offers numerous advantages over conventional barrel profiles, including elimination of corners/ edges making them considerably easier to clean and maintaining uniform precision even after a high number of rounds have been fired.
   • LOADED CHAMBER INDICATOR: The extractor (10) serves as a loaded chamber indicator (Picture 1) to comply with the laws of certain states and its position may visually and physically indicate whether there is a cartridge in the chamber of the pistol. When the chamber i sunloaded the extractor is depressed (Picture 2) and when the chamber is loaded the extractor pivots out from the slide (Picture 3).
   • WARNING! Although your GLOCK pistol has a loaded chamber indicator, it is a mechanical device, which could fail. Never rely solely on a loaded chamber indicator or your memory to determine whether your GLOCK pistol is loaded or unloaded. Always remove the magazine, retract and lock the slide by pulling it fully to the rear and then visually and physically (with your finger) check to make sure there is not a cartridge in the chamber, as fully described in the Unloading Procedure and Safety Check, Chapter 8 (Pages 19-20).

Pistol nomenclature

The functioning of the Pistol

• The following describes how the GLOCK semi-automatic Safe Action® pistol functions.
• When the pistol is in the ready-to-fire condition – fully loaded with a round in the chamber and a loaded magazine inserted – the trigger is in the forward position with the trigger safety positively protruding from the trigger (26), the firing pin spring (6) is under partial tension, and the drop safety is engaged.
• The trigger safety prevents the trigger from being moved rearward and the firing pin safety (8) blocks the firing pin (4) from moving forward.
• ( Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).
• When the trigger safety is disengaged by depressing it until it is even with the trigger, the trigger can be pulled rearward.
• When the trigger slack is taken up to the first pressure point by pulling it rearward about 0.2 in. / 5mm, the trigger bar raises and disengages the firing pin safety and the firing pin is placed under additional tension.
• When the trigger is pulled fully to the rear, the trigger bar separates from the end of the firing pin and drops down. This causes the firing pin to release and move forward under pressure to strike the primer of the cartridge in the chamber, thereby causing the pistol to fire.
• The recoil impulse moves the slide (1) backward. After the slide has moved about 0.1. in. / 2.5mm to the rear, the locking action between the barrel (2) and the slide is released, and the barrel swings downward over the locking block (22) and is retained in this position.
• The slide then continues to move fully rearward by itself, during the process of which the fired cartridge case is pulled out of the chamber of the barrel by the extractor (10), and is thrown out to the right by the ejector (23).
• The ramp in the slide rails then separates the connector (24) from the trigger bar causing the trigger bar to be lifted by the trigger spring (25) and brought back into the path of the firing pin lug.

The recoil spring (3) then brings the slide forward. As the slide moves forward and the trigger is released, the following occur:

• the trigger bar is pushed onto the safety ramp by the firing pin;
• the firing pin safety is brought into engagement;
• the firing pin is put back under partial tension;
• the next cartridge is stripped from the magazine and placed into the chamber;
• the barrel is locked with the slide; and
• the trigger returns to the forward position with the trigger safety positively protruding from the trigger.

Each round is automatically loaded until the magazine is empty. After the last round in the magazine has been fired, the slide will remain locked open in the rearward position by the slide stop lever (27). (Note: If you are firing your GLOCK pistol without a magazine inserted, the slide will not remain locked open in the rearward position after firing).

Loading

• WARNING! Your GLOCK pistol does not have a conventional manual safety and it will fire if the trigger is pulled when there is a around in the chamber.
• WARNING! Do not use reloaded, remanufactured, or handloaded ammunition because it may not meet applicable SAAMI, CIP or NATO standards and could cause death, serious personal injury, and/or property damage. Only use high quality commercially manufactured ammunition in the same caliber as your GLOCK pistol. (Note: Use of reloaded, remanufactured, or handloaded ammunition will void the warranty).
• WARNING! Before firing your GLOCK pistol, run a clean patch through the barrel, from the chamber end, using the cleaning rod. Repeat this procedure until the patch comes out of the barrel with no gun oil or lubricant on it because any obstruction in the barrel could prevent the pistol from firing properly and result in death or serious personal injury and/or damage to the pistol. To load the magazine, press each cartridge into the magazine from the front with the cartridge bottom first – against the force of the magazine spring (Pictures 4-5). Insert the magazine into the magazine well until the magazine catch (19) locks into place (Picture 6). (Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).
• If slide (1) is in the forward position, hold your  GLOCK pistol with your firing hand and, while keeping your finger off of the trigger and outside of the trigger guard, grasp the rear of the slide at the serrations with your other hand and pull the slide fully back (Picture 7) and then release it, allowing it to return to the fully forward position (Picture 8). or
• If the slide is locked in the rearward position, either press the slide stop lever (27) down to release the slide and return it to the fully forward position or grasp the rear of the slide at the serrations with your other hand and pull the slide fully back and then release it, allowing it to return to the fully forward position.
• The pistol is now loaded and ready to be fired by pulling the trigger.

Firing

• WARNING! Always be sure that the barrel of your GLOCK pistol is clear of obstructions before firing it. Remove any obstructions before firing your GLOCK pistol so that it will function safely and correctly. Any obstruction in the barrel could prevent the pistol from firing properly and result in death or serious personal injury and/or damage to the pistol.
• WARNING! In case of a failure to fire, continue to hold your GLOCK pistol pointed toward the target for at least 30 seconds. If a hangfire (slow ignition) has occurred, the cartridge should fire within approximately 30 seconds. If the cartridge has not fired, remove the magazine, eject the cartridge from the chamber, and examine its primer. If the firing pin indentation is light, off-center, or non-existent, stop using your GLOCK pistol and have it examined by the GLOCK entity for your region or a GLOCK-Certified Armorer. If the firing pin indentation on the primer appears normal (compared to similar previously fired cartridges) the cartridge may be defective. Separate the cartridge from other live ammunition and empty cases, reload your GLOCK pistol, and resume firing.
  • ( Note: Dispose of misfired cartridges in accordance with the ammunition manufacturer’s instructions.
• WARNING! Never use your GLOCK pistol if it fails to function properly, and never force the slide closed on a jammed cartridge because it could cause the cartridge to explode.
• WARNING! Always wear safety glasses and ear protection when firing your GLOCK pistol to protect your eyes and hearing.
• WARNING! Always be sure that your backstop is adequate to stop and contain bullets before firing so that you do not hit anything outside of the shooting range area. A bullet could travel through or past your target as far as 2 miles (approximately 3km). If in doubt, do not shoot.
• WARNING! Never shoot at a hard surface, such as a rock, or a liquid surface, such as water, because a bullet may ricochet and travel in any direction, striking you or someone else.
• WARNING! Your GLOCK pistol does not have a conventional manual safety and it will fire if the trigger is pulled when there is a round in the chamber.
• WARNING! Hot gasses and powder are forcefully expelled from the ports on top of the slide of GLOCK C (Compensated) model pistols when they are fired. Never place your hand on top of the slide and make certain that no part of your body is near or above the ports on the barrel when firing it.
• WARNING! Always put a responsible and competent person in charge to maintain safety, discipline and control when a group is firing at a range, to reduce the likelihood of a negligent discharge.
• WARNING! Always carry your GLOCK pistol unloaded with the slide locked open in the rearward position while on a range until preparing to fire. Always keep the pistol pointed towards the backstop when loading, firing and unloading it.
• CAUTION! When ready to fire be sure that the area behind the slide is clear (check your thumb) and do not hold the pistol near your body, because the slide will move forcefully rearward when the pistol is fired.
  • ( Note: When firing with a two-hand grip, the thumb of the weak hand should be on the weak-hand side of the pistol, never behind the slide).
• CAUTION! Always keep yourself and others clear of the ejection port because spent cartridges are hot and are ejected with enough force to cause injury. Never touch the slide or barrel immediately after firing because they may be hot and could cause burns.
• CAUTION! Except when the slide is locked in the fully rearward position and you are checking to ensure that the chamber is empty, never place your fingers in the ejection port because they could be injured by the movement of the slide.
• CAUTION! Never fire your GLOCK pistol near an animal unless it is trained to accept that noise. An animal’s startled reaction could injure it, or cause it to injure you or someone else.
• When the pistol is loaded with a cartridge in the chamber, it can be fired by simply pulling the trigger (26) fully to the rear. (Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).
• After firing the last cartridge in the magazine, the slide (1) will remain locked open in the rearward position (Picture 9). (Note: If you are firing your GLOCK pistol without a magazine inserted, the slide will not remain locked open in the rearward position after firing).

Clearing malfunctions (jams)

• WARNING! In case of a failure to fire, continue to hold your GLOCK pistol pointed toward the target for at least 30 seconds. If a hangfire (slow ignition) has occurred, the cartridge should fire within approximately 30 seconds. If the cartridge has not fired, remove the magazine, eject the cartridge from the chamber, and examine its primer. If the firing pin indentation is light, off-center, or non-existent, stop using your GLOCK pistol and have it examined by the GLOCK entity for your region or a GLOCK-Certified Armorer. If the firing pin indentation on the primer appears normal (compared to similar previously fired cartridges) the cartridge may be defective. Separate the cartridge from other live ammunition and empty cases, reload your GLOCK pistol and resume firing. (Note: Dispose of misfired cartridges in accordance with the ammunition manufacturer’s instructions.
• WARNING! If an unfired cartridge hangs up, jams, or binds while being chambered, do not attempt to force it into the chamber by pushing or striking the slide to attempt to close it because this could cause the cartridge to burst resulting in fragments of the cartridge flying out of the ejection port with sufficient force to cause death, serious personal injury and/or property damage.
• WARNING! Always wear safety glasses when attempting to remove a jammed cartridge to protect your eyes. All auto-loading pistols may occasionally experience a malfunction (jam) related to the feeding of ammunition. Most malfunctions are caused by improper ammunition, an improper grip on the pistol when shooting (limp writing), improper lubrication, or a damaged magazine. To minimize the chance of malfunctions (jams), regularly perform preventive maintenance on your GLOCK pistol pursuant to the instructions in Chapter 10 of this manual. If you experience a malfunction (jam) while using a new brand, type, or lot of ammunition, try firing another type of ammunition to determine whether the ammunition was the source of the malfunction (jam).
• WARNING! Do not use reloaded, remanufactured, or hand-loaded ammunition because it may not be applicable to SAAMI, CIP, or NATO standards and could cause death, serious personal injury, and/or property damage. Only use high-quality commercially manufactured ammunition in the same caliber as your GLOCK pistol. (Note: Use of reloaded, remanufactured, or hand loaded ammunition will void the warranty).
  • If a cartridge becomes jammed while being chambered or extracted, follow the steps below to remove it.
  • While keeping the muzzle of your GLOCK pistol pointed in a safe direction (a safe direction is one in which no one can possibly be injured in the event of an unintentional discharge), remove the magazine if possible by pressing the magazine catch (19).
  • ( Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).
  • While holding the grip with your firing hand, with your finger off of the trigger (26) and outside of the trigger guard, grasp the rear of the slide (1) at the serrations with your other hand and pull the slide fully back.
  • Lock the slide in the rearward (open) position by pushing up on the slide stop lever (27) and slowly releasing the slide from the fully rearward position until it locks in the open position.
  • If the above steps have not removed the jammed cartridge, carefully remove the jammed cartridge from the chamber using your fingers or a pointed wooden dowel.
• WARNING! Do not use a metal tool to attempt to remove an unfired cartridge because it could ignite the primer and cause the cartridge to rupture resulting in fragments of the cartridge flying out of the ejection port with sufficient force to cause death, serious personal injury and/or property damage.
  • If you are unable to remove the jammed cartridge using the above steps, leave the slide locked in the rearward (open) position and contact the GLOCK entity for your region or a GLOCK-Certified Armorer.

• WARNING! Always make sure that no ammunition is located in the area where you clean your GLOCK pistol. Lubricant can affect the primer and powder in ammunition and cause it to malfunction. This could result in a bullet being pushed into the barrel of your GLOCK pistol and getting stuck in the barrel could cause the barrel to burst and result in death or serious personal injury, in addition to damaging the pistol.
• WARNING! Do not put lubricant or gun oil inside the firing pin channel. Make sure that the magazine (inside and out) and breech face are wiped dry before reassembling your GLOCK pistol. Leaving lubricant in these areas could cause contaminations of primers and failure to fire.
• NOTICE! As with any semi-automatic pistol, your GLOCK pistol should be field-stripped (disassembled into its major components) every time it is cleaned. Cleaning without field stripping, by merely locking the slide to the rear and inserting the cleaning rod from the muzzle, can cause dirt, oil and lubricant to build up inside the pistol causing malfunctions.

Like all mechanical devices, your GLOCK pistol must be properly maintained to ensure reliable functioning and long service life. Taking proper care of your pistol will also preserve its value. Although your GLOCK pistol is highly resistant to adverse conditions, you should follow a regularly scheduled maintenance program to ensure that it is properly cleaned and lubricated to prevent corrosion and to remove accumulated dirt and debris that can affect the action and operation of your pistol.
Your GLOCK pistol should be cleaned and lubricated as follows:

1. when brand new, before first time it is fired, plus
2. after each time it is fired, plus
3. as required. This will be determined by your pistol’s exposure to adverse conditions during storage or use such as rain, snow, perspiration, salt water, dirt, dust, lint, etc. Additionally, your pistol should be cleaned and inspected if it has been dropped or if any broken parts are suspected or malfunctions experienced, plus
4. at least once a year.

To clean your GLOCK pistol, first disassemble it into its five main components, the slide (1), barrel (2), recoil spring assembly (3), frame (17), and magazine, pursuant to the instructions in Chapter 9. Always use cleaning patches and brushes of the proper size for the caliber of your GLOCK pistol.
( Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).

BARREL: Clean the barrel as follows:

1. Wet a cleaning patch with lubricant and run it through the barrel, from the chamber end, several times using a cleaning rod.
2. Wet a bristled cleaning brush with lubricant and run it back and forth in the barrel, from the chamber end (Picture 28), using a cleaning rod to remove any fouling and burned powder.
3. Wet another cleaning patch with lubricant and run it through the barrel once, from the chamber end, with the cleaning rod and examine it. If it is not clean, repeat steps 2 and 3 until the patch remains clean after being run through the barrel.
4. Run a clean patch through the barrel, from the chamber end, using the cleaning rod.
5. Lightly wet a clean patch with gun oil or lubricant and run it through the barrel from the chamber end.
6. Before firing your GLOCK pistol, run a clean patch through the barrel, from the chamber end, using the cleaning rod. Repeat this procedure until the patch comes out of the barrel with no gun oil or lubricant on it.
   • NOTICE! If you will be storing your GLOCK pistol do not perform step 6 until you are ready to use it.
7. Wet a nylon bristle brush with lubricant and thoroughly brush the outside of the barrel to remove any dirt or residue.
8. Wipe the outside of the barrel dry with a clean patch and examine it. If it is not clean, repeat steps 7 and 8 until the patch remains clean.
   • SLIDE: (Note: The copper-colored lubricant on portions of the slide of brand new GLOCK pistols is intended to help provide long-term lubrication and should not be removed).

Clean the slide as follows:

1. Wet a nylon bristle brush with lubricant and thoroughly brush the rail cuts in the slide where it meets the slide rails on the frame (Picture 29).
2. Wipe the rail cuts in the slide with a clean patch and examine it. If it is not clean, repeat steps 1 and 2 until the patch remains clean (except copper-colored long-term lubrication).
3. Wet a nylon bristle brush with lubricant and, while holding the slide with the muzzle end facing down, brush the breech face and the area under the extractor claw (Picture 29).
4. While holding the slide with the muzzle end facing down, wipe the breech face and the area under the extractor claw (10) (Picture 29) with a clean patch and examine it. If it is not clean, repeat steps three and four until the patch remains clean.
5. Check all other exposed areas of the slide for cleanliness. If any dirt or debris is found, remove it with lubricant using a nylon bristle brush, patch, or a clean, soft cloth.
6. Wipe the exposed areas of the slide that you have cleaned in step 5 with a clean patch and examine it. If it is not clean, repeat steps 5 and 6 until the patch remains clean.

FRAME: Check the frame for cleanliness. If necessary, clean the frame as follows:

1. Wipe exposed parts of the frame with a clean, soft cloth that has been slightly dampened with lubricant.
2. Wipe the exposed areas of the frame that you have cleaned in step 1 with a clean patch and examine it. If it is not clean, repeat steps 1 and 2 until the patch remains clean.

After you have cleaned your GLOCK pistol, lubricate it as follows:

1. Slightly dampen a clean patch with gun oil or lubricant and wipe the outside of the barrel, including the barrel hood and lugs (Picture 30), the inside top of the slide in front of the ejection port where the barrel hood rubs against the slide, and the opening that the barrel slides through in front of the slide.
2. Place a drop of gun oil or lubricant where the rear end of the trigger bar (26) touches the connector (24) at the right rear corner of the frame (Picture 31).
3. Spread one drop of gun oil or lubricant along the entire length of each slide rail cut (Picture 32).
4. Slightly dampen a clean patch with gun oil or lubricant and wipe the exterior surfaces of the slide.

CAUTION! GLOCK pistols are designed to operate properly with only small amounts of lubrication. Do not over-lubricate your GLOCK pistol because too much lubricant can collect unburned powder and other debris and prevent your GLOCK pistol from functioning properly.

After you have finished cleaning and lubricating your GLOCK pistol, you should perform a limited (userlevel) inspection to help confirm that it is functioning properly. If your pistol fails any of the following checks, contact the GLOCK entity for your region or a GLOCK-Certified Armorer. To inspect your GLOCK pistol, follow these steps before reassembling it:

1. EXTERNAL INSPECTION: Inspect the outside of your frame and slide for dirt, corrosion, or any visible damage. Pay special attention to the sights (15 & 16a), trigger and trigger safety (26), slide stop lever (27), magazine catch (19), and extractor (10).
2. BARREL INSPECTION: Inspect the barrel (2) for dirt, leading, bulges, cracks or obstructions.
   • WARNING! Do not use a cracked, bulged, or obstructed barrel. Contact the GLOCK entity for your region or a GLOCK-Certified Armorer for repair or replacement.
3. FIRING PIN SAFETY TEST: Hold the slide and pull the lug of the firing pin (4) (Picture 33), all the way to the rear of the slide and then ease it forward until it stops in contact with the firing pin safety (8).
   • NOTICE! The firing pin is held in the forward position under spring pressure. Do not allow the firing pin to snap forward against the firing pin safety because this could cause damage to the firing pin and/or the firing pin safety. Then press the lug of the firing pin (4) forward with your forefinger using moderate force (approximately 5-8 lbs. / 23-36 N). The firing pin must not move forward past the firing pin safety (8), and must not protrude from the breech face of the slide.
   • WARNING! If the firing pin safety fails to keep the firing pin from moving forward. DO NOT LOAD OR FIRE YOUR GLOCK PISTOL. Instead, have it inspected and repaired by the GLOCK entity for your region or a GLOCK-Certified Armorer.
4. FIRING PIN: Hold the slide with the muzzle end downward, and press the firing pin safety  into the slide with your fingertip. The firing pinshould move downward, and the tip of the firing pin should protrude from the breech face. (Note: On brand new pistols you may need to apply light downward pressure to the rear of the firing pin lug with your finger to assist the firing pin in moving downward).
5. FIRING PIN CHANNEL: Hold the firing pin safety depressed with your fingertip, and vigorously shake the slide from end to end. You should hear the firing pin moving freely in the firing pin channel.
6. EXTRACTOR: Look across the breech face to inspect the extractor for cleanliness and to be sure the extractor claw is not broken.
7. EJECTOR: Inspect the ejector (23) (in the frame of the pistol) to ensure that it is intact (not broken) (Picture 34).
8. SLIDE STOP LEVER TEST: Pull upward on the  slide stop lever and release. The lever shouldsnap down sharply into the frame. If the lever’s return to the downward position is sluggish, or it remains in the upward position, contact the GLOCK entity for your region or a GLOCKCertified Armorer.
9. MAGAZINE INSPECTION: Inspect all magazines for dirt or visible damage, taking special care to look for spread or damaged feed lips or broken magazine followers (32) (Picture 35). Press down on the follower with your fingertip and release. The follower should spring fully upward, and should not stick inside the magazine tube.

Reassembly and inspection

WARNING! Always wear safety glasses when reassembling your GLOCK pistol to protect your eyes from springs.

To reassemble your GLOCK pistol, follow the instructions below.

1. Holding the barrel (2) by the barrel locking cams, insert it into the slide (1) by pushing it down and in (Picture 36). (Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).
2. Insert the recoil spring assembly (3) into the slide by placing the small end of the recoil spring assembly in the indentation in the front of the slide and pressing the other end of the recoil spring assembly towards the front of the slide to compress the spring and pushing down until the large end of the recoil spring assembly rests in the second (semi-circular) notch on the barrel locking cams (Pictures 37-39).
3. Holding the frame in your firing hand, with your finger off of the trigger and outside of the trigger guard, place the slide on top of the frame (17) in front of the slide rails and push the slide towards the back of the frame until the slide lock (21) snaps up to lock the slide into place (Picture 40).

After you have reassembled your GLOCK pistol, you should inspect it to ensure that it is working properly by performing the following steps:

1. TRIGGER SAFETY TEST: Confirm that your GLOCK pistol is unloaded by making sure the  magazine is not inserted in the pistol and visually and physically (with your finger) checking to make sure that there is not a cartridge in the chamber. Cycle the slide to reset the trigger to the forward position. With the muzzle of your GLOCK pistol pointed in a safe direction (a safe direction is one in which no one can possibly be injured in the event of an unintentional discharge), grasp the sides of the trigger (without touching or depressing the trigger safety) and attempt to pull the trigger to the rear (Picture 41). The trigger safety should prevent rearward movement of the trigger, and the pistol should not dry fire.
   • WARNING! If the trigger safety fails to keep the trigger from moving rearward, and the pistol dry fires, DO NOT LOAD OR FIRE YOUR GLOCK PISTOL and have it inspected and repaired by the GLOCK entity for your region or a GLOCK-Certified Armorer.
2. TRIGGER RESET TEST: With the muzzle of your GLOCK pistol pointed in a safe direction, pull the trigger and hold the trigger to the rear. You should hear and feel the firing pin release. While continuing to hold the trigger to the rear, pull the slide to the rear (Picture 42) and release it, allowing it to snap forward. Now release the trigger. The trigger should reset to its forward position. Repeat the trigger reset test several times.
3. SLIDE LOCK-OPEN TEST: Insert an EMPTY magazine into your pistol. Pull the slide fully to the rear. The slide should lock open (Picture 43). Repeat the slide lock-open test using each of your EMPTY magazines. In addition to the limited (user level) inspection described in this manual, GLOCK pistols carried by law enforcement, security, or military personnel and other GLOCK pistols subjected to heavy usage, should be inspected periodically by a GLOCK-Certified Armorer, or by returning the pistols to the GLOCK entity for your region for inspection. Although the appropriate inspection interval will depend on the conditions of use, a reasonable rule of thumb for law enforcement, security, or military personnel is that the pistols should be inspected by a GLOCK-Certified Armorer once a year. To locate a GLOCK-Certified Armorer in your area or before returning the pistol for inspection, contact your local GLOCK dealer or the GLOCK entity for your region.

Pistol customizing
GLOCK Gen4/Gen5/Crossover models Backstraps Customizing the frame
GLOCK Gen4, Gen5 and Crossover pistols feature interchangeable backstraps with or without a beaver tail to vary the circumference and the shape of the frame (Pictures 44-45). Without a backstrap attached, the Gen4, Gen5 and Crossover models have the same frame circumference as the SF models. The medium backstrap adds an additional 0.08 in. / 2mm to the circumference of the frame. The large backstrap adds 0.16 in. / 4mm to the circumference of the frame. The backstraps with a beaver tail come with the same sizes and additionally they are enlarged at the top allowing the shooter’s hand to better stabilize the pistol.

Available Options

WARNING! Make sure that your GLOCK pistol is unloaded (magazine removed and chamber empty) before changing the backstraps.

The backstraps (17a/b, 17c/d) are changed as follows.
( Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).

1. Remove the trigger housing pin (29/29a) with the multifunctional clip by pushing it from one side to the other and completely out of the frame (17) (Picture 46).
2. If a backstrap is already installed, remove it (Picture 47/48).
3. If you will be installing a backstrap, attach it to the frame by hooking the bottom of the backstrap to the bottom rear of the frame, then pivoting the top of the backstrap forward and onto the frame (Picture 49). If you are installing a beavertail backstrap press it to the frame, until it clicks onto the small nose of the modular backstrap (MBS/Gen5/Crossover) frame.
   • ( Note: The beavertail backstrap also fits on older gen4 pistols without the small nose is only an additional fixture (Picture 50)).
4. If you did not install a backstrap, install the short trigger housing pin by pushing it into the corresponding hole in the rear of the frame with the flat side of the multifunctional clip until it is completely centered in the frame. If you installed a backstrap, hold it in place against the frame while installing the long trigger housing pin by pushing it into the corresponding hole in the rear of the frame with the flat side of the multifunctional clip until it is completely centered in the frame (Picture 51).
5. Inspect the pistol to confirm that you have installed the correct trigger housing pin by ensuring that it is flush with the frame. If you installed the long trigger housing pin without a backstrap, it will protrude outside of the frame and could cause discomfort while shooting. If you installed the short trigger housing pin with a backstrap, it will not fully extend to the sides of the frame and may allow the backstrap to come loose.

GLOCK Gen4/Gen5/Crossover/Slimline models Reversible magazine catch Reversing the magazine catch
GLOCK Gen4, Gen5, Crossover and Slimline models also feature an extended magazine catch (19) that is reversible for right or left hand use. Standard GLOCK magazines can be used in Gen4, Gen5 and Crossover pistols when the magazine catch is installed in the right handed position. New Style magazines are required when the magazine catch is installed in the left handed position. The magazine catch on the GLOCK Gen4, Gen5 and Crossover models can be reversed by proceeding as follows. (Note: The pistol must be field stripped pursuant to the instructions in Chapter 9 before the magazine catch can be reversed).

1. Hold the frame (17) so that you can see into the magazine well.
2. While pressing against both sides of the magazine catch to prevent it from moving, use a small flat head screwdriver to push the magazine catch spring (18) up and towards the “U” shaped cut in the magazine catch (Picture 52) to release the spring tension on the magazine catch. Use pliers to pull the magazine catch spring upwards and out of the receiver (Picture 53).
3. Remove the magazine catch by pulling it out of the frame from the outside (Picture 54).
4. Reverse the magazine catch and reinsert it in the other side of the frame from the outside (Picture 55).
5. Insert the magazine catch spring with the pliers in the provided hole and push this down. Make sure to seat it completely. Using a small flat head screwdriver, push the end of the magazine catch spring back into the “U” shaped cut in the magazine catch.
6. Insert an empty magazine into the frame and press the magazine release to confirm that it operates correctly. Repeat several times.
7. Reassemble your GLOCK pistol according to the instructions in Chapter 11.

Pistol Configurations

GLOCK C (Compensated)

WARNING! Hot gasses and powder are forcefully expelled from the ports on top of the slide of GLOCK C (Compensated) model pistols when they are fired. Never place your hand on top of the slide and make certain that no part of your body is covering the ports on the barrel when firing it. GLOCK C models are equipped with an integrated compensator (Pictures 56-57), making the pistol even more controllable during rapid fire, thereby increasing accuracy. The compensator consists of two longitudinal openings in the barrel and slide of the pistol arranged in a “V-position”. This minimizes front-sight blackening through powder gasses. The C configuration is available in GLOCK models 17, 19, 21, 24 and 31.
GLOCK SF (Short Frame)
The circumference of the frame on the SF models is reduced at the rear or “backstrap” (Picture 58), which will appeal to shooters with smaller hands and offer increased comfort and control to all. The SF configuration is available in GLOCK models 20, 21, 29, and 30. Not available in CA and MA.
GLOCK MOS (Modular Optic System)
GLOCK pistol models in MOS configuration offer a set of adapter plates in order to mount different optical systems (Picture 59). The MOS configuration is not available for all GLOCK pistol models. The GLOCK 43X and 48 models with an MOS configuration have slide cuts designed for specific micro-optics and do not include adapter plates.

GLOCK Gen4
The frame design of the Gen4 is modular and adaptable and offers a frame with finger grooves and a reversible enhanced magazine release.
GLOCK Front Serrations (FS)
The front serrations (FS) provide an additional tactile surface choice when manipulating the slide, giving the operator positive traction even with wet or sweaty hands. This design offers the advantage for professional users to do a fast press check before and after firing. Standard for GLOCK Gen5 models.
GLOCK Oval magazine catch
The oval magazine catch (Picture 62) was specifically developed for comfort- conscious and left-handed users.
Note: Frame adjustment is required at the factory. Only available for special models.

GLOCK RTF2
(Rough textured frame, version 2) The RTF2 models feature pyramid-shaped cubics on the frame (Picture 63) for an improved grip. The RFT2 configuration is available in GLOCK models 17, 19, 22, 23 and 34. Only available for special models.
Internal Locking Device
Some GLOCK pistols can be ordered with an optional factory-installed internal locking device designed to render the pistol inoperable by preventing the trigger from being pulled fully to the rear.
( Note: If your GLOCK pistol contains the optional internal locking device, it has been shipped in the locked condition). To unlock the pistol, insert the specialized key into the keyhole located at the bottom of the frame behind the magazine well, and rotate it clockwise one full turn (Picture 64). The pistol is now fully operational. To lock the internal locking device, insert the key into the keyhole and rotate it counterclockwise one full turn. A white tab will protrude from the back of the frame to indicate that the pistol is locked (Picture 65). Only available for special models.
WARNING! Never leave your GLOCK pistol where it could be accessed by a child or other unauthorized person. Store the key to the internal locking device separately from your GLOCK pistol.

Pistol Options

Several options are available to customize your GLOCK pistol. The general availability of these options is dependent on region and model.
( Note: The part numbers referenced in parenthesis throughout this manual correspond to the list of component parts and exploded drawing on pages 46-51).
REAR SIGHTS:
Most GLOCK pistol models come standard with polymer rear sights (15), which have a white contrast insert for rapid aim. Some models come standard with adjustable rear sights, which allow the point of impact to be adjusted for both windage and elevation, using the supplied tool. Steel rear sights with a white contrast insert for quick aim, steel luminescent sights and steel night sights with tritium contrast points, which appear white in the day light and illuminated in color at night are available as options. The fixed rear sights are available in different dimensions. Any one of the available rear sights can be easily installed on any GLOCK pistol by a GLOCK-Certified Armorer.
FRONT SIGHTS:
All GLOCK pistol models come standard with polymer front sights (16a), which provide excellent damping characteristics on impact. Steel front sights with a white contrast point, steel luminescent sights and steel night sights with a self-illuminating tritium contrast point are available as options. The front sights are available in different dimensions. The front sights can be easily installed by a GLOCK-Certified Armorer.
CONNECTORS/TRIGGER SPRINGS:
GLOCK offers different connectors (24) and trigger springs (25), which can be used in combination to adjust the trigger pull from approximately 4.5-11.2 lbs. / 20-50N. The available trigger pull combinations can easily be changed by a GLOCK-Certified Armorer.

SLIDE STOP LEVER: Most GLOCK pistol models come with the standard slide stop lever (27), which has flat dimensions for concealed carry. Some models come with an extended slide stop lever with comfortable thumb rest, especially suitable for left-handed users. GLOCK Gen5 models feature an ambidextrous slide stop lever. A standard or extended slide stop lever can easily be installed on any GLOCK pistol by a GLOCK-Certified Armorer.
MAGAZINE CATCH: Most GLOCK pistol models come with the standard magazine catch (19) that has flat dimensions designed to protect against inadvertent magazine release. Some models come with an extended magazine catch that produces the decisive tenths of a second increase in the speed of changing the magazine for dynamic shooting sport disciplines. GLOCK Gen4 and Gen5 models feature a reversible magazine catch. A standard or extended magazine catch can easily be installed on any GLOCK pistol by a GLOCK-Certified Armorer.

Cable lock

Your GLOCK pistol comes standard (USA and Canada only) with a cable lock (Picture 66). The cable must be installed on an unloaded pistol with the slide locked in the open (rearward position). The cable must be placed through the ejection port and out of the magazine well. Insert the end of the cable into the lock and make sure it is locked into place.

WARNING! Never leave your GLOCK pistol where it could be accessed by a child or other unauthorized person. Store the key to the cable lock separately from your GLOCK pistol.

Safety Warnings

State-required Safety Warnings

Certain states have laws requiring that specific warnings be provided with handguns sold in those states. Because GLOCK pistols are sold in all states, the safety warnings required by all states are included in this manual.
California:

WARNING! “Firearms must be handled responsibly and securely stored to prevent access by children and other unauthorized users. California has strict laws pertaining to firearms, and you may be fined or imprisoned if you fail to comply with them. Visit the Web site of the California Attorney General at https://oag.ca.gov/firearms. for information on firearm laws applicable to you and how you can comply. Prevent child access by always keeping guns locked away and unloaded when not in use. If you keep a loaded firearm where a child obtains and improperly uses it, you may be fined or sent to prison.”
ADVERTENCIA! “Las armas de fuego deben operarse con responsabilidad y mantenerse guardadas en un lugar seguro fuera del alcance de niños o usuarios no autorizados. California tiene leyes estrictas con respecto a armas de fuego, y Usted puede ser multado o enviado a prisión por su incumplimiento con estas regulaciones. Visite la página web del Fiscal General de California en https://oag.ca.gov/firearms. para obtener información acerca de las regulaciones sobre armas de fuego aplicables a su situación y que debe hacer para cumplir con ellas. Prevenga que niños tengan acceso a armas de fuego manteniéndolas descargadas y guardadas bajo Ilave cuando no las esté utilizando. Si Usted mantiene un arma de fuego cargada donde un niño pueda tener acceso y la usa de manera inapropiada, Usted puede resultar multado o enviado a prisión.”

Connecticut:
“UNLAWFUL STORAGE OF A LOADED FIREARM MAY RESULT IN IMPRISONMENT OR FINE.”
Florida:
“IT IS UNLAWFUL, AND PUNISHABLE BY IMPRISONMENT AND FINE, FOR ANY ADULT TO STORE OR LEAVE A FIREARM IN ANY PLACE WITHIN THE REACH OR EASY ACCESS OF A MINOR UNDER 18 YEARS OF AGE OR TO KNOWINGLY SELL OR OTHERWISE TRANSFER OWNERSHIP OR POSSESSION OF A FIREARM TO A MINOR OR A PERSON OF UNSOUND MIND.”
Maine:
“ENDANGERING THE WELFARE OF A CHILD IS A CRIME. IF YOU LEAVE A FIREARM AND AMMUNITION WITHIN EASY ACCESS OF A CHILD, YOU MAY BE SUBJECT TO FINE, IMPRISONMENT OR BOTH. KEEP FIREARMS AND AMMUNITION LOCKED UP. USE TRIGGER LOCKS.”
Maryland:
WARNING: “CHILDREN CAN OPERATE FIREARMS WHICH MAY CAUSE DEATH OR SERIOUS INJURY. IT IS A CRIME TO STORE OR LEAVE A LOADED FIREARM IN ANY LOCATION WHERE AN INDIVIDUAL KNEW OR SHOULD HAVE KNOWN THAT AN UNSUPERVISED MINOR WOULD GAIN ACCESS TO THE FIREARM. STORE YOUR FIREARM RESPONSIBLY!”
Massachusetts:
“WARNING FROM THE MASSACHUSETTS ATTORNEY GENERAL: This handgun is not equipped with a device that fully blocks use by unauthorized users. More than 200,000 firearms like this one are stolen from their owners every year in the United States. In addition, there are more than a thousand suicides each year by younger children and teenagers who get access to firearms. Hundreds more die from accidental discharge. It is likely that many more children sustain serious wounds, or inflict such wounds accidentally on others. In order to limit the chance of such misuse, it is imperative that you keep this weapon locked in a secure place and take reasonable preventive steps necessary to limit the possibility of theft or accident. Failure to take reasonable preventative steps may result in innocent lives being lost, and in some circumstances may result in your liability for these deaths.” “IT IS UNLAWFUL TO STORE OR KEEP A FIREARM, RIFLE, SHOTGUN OR MACHINE GUN IN ANY PLACE UNLESS THAT WEAPON IS EQUIPPED WITH A TAMPER-RESISTANT SAFETY DEVICE OR IS STORED OR KEPT IN A SECURELY LOCKED CONTAINER.”
New Jersey:
“IT IS A CRIMINAL OFFENSE TO LEAVE A LOADED FIREARM WITHIN EASY ACCESS OF A MINOR.”
New York City:
“THE USE OF A LOCKING DEVICE OR SAFETY LOCK IS ONLY ONE ASPECT OF RESPONSIBLE FIREARMS STORAGE. FOR INCREASED SAFETY, FIREARMS SHOULD BE STORED UNLOADED AND LOCKED IN A LOCATION THAT IS BOTH SEPARATE FROM THEIR AMMUNITION AND INACCESSIBLE TO CHILDREN AND OTHER UNAUTHORIZED PERSONS.”
North Carolina:
“IT IS UNLAWFUL TO STORE OR LEAVE A FIREARM THAT CAN BE DISCHARGED IN A MANNER THAT A REASONABLE PERSON SHOULD KNOW IS ACCESSIBLE TO A MINOR.”
Texas:
“IT IS UNLAWFUL TO STORE, TRANSPORT, OR ABANDON AN UNSECURED FIREARM IN A PLACE WHERE CHILDREN ARE LIKELY TO BE AND CAN OBTAIN ACCESS TO THE FIREARM.”
Wisconsin:
“IF YOU LEAVE A LOADED FIREARM WITHIN THE REACH OR EASY ACCESS OF A CHILD YOU MAY BE FINED OR IMPRISONED OR BOTH IF THE CHILD IMPROPERLY DISCHARGES, POSSESSES, OR EXHIBITS THE FIREARM.” State laws and regulations concerning firearms change constantly. Please check with your local federally licensed firearm dealer or state police for additional laws and regulations regarding the storage and use of firearms in your state.
