How to Field Strip and Reassemble a Glock for Maintenance and Inspection

Firearm ownership carries with it a profound sense of responsibility, emphasizing not only the right to bear arms but also the duty to understand and maintain them.

Knowledge of a firearm's components is crucial, as it allows the owner to appreciate the complexity and functionality of the weapon, ensuring safe and effective use.

Regular maintenance is key to preserving a firearm's condition, functionality, and longevity. This involves routine cleaning, proper storage, and timely repairs, all of which are essential to prevent malfunctions and accidents.

For Glock owners, routine firearm maintenance generally includes a fundamental skill that allows you to clean, maintain, and inspect your firearm thoroughly, called Field Stripping.

In this article, we'll explore a step-by-step guide on how to safely and successfully field strip your Glock pistol in ten easy steps, emphasizing the importance of safety and responsible gun ownership.


Firearm Safety Procedures

Before delving into the steps, it is crucial to emphasize the importance of safety. Below are the Four Universal Firearm Safety Rules, widely recognized and taught by law enforcement, military, and civilians.

Treat All Guns as if They Are Loaded
Always handle a firearm with the same care you would if you knew it was loaded, even if you believe it to be unloaded. This mindset helps instill a constant sense of caution.

Never Point a Firearm at Anything You Do Not Intend to Shoot
Always keep the muzzle pointed in a safe direction, away from unintended targets. This rule is crucial for preventing accidental harm or damage.

Keep Your Finger Off the Trigger Until Ready to Shoot
Your finger should rest outside the trigger guard until you have made the conscious decision to shoot. This helps prevent accidental discharges.

Be Sure of Your Target and What is Beyond It
Before firing, be aware not only of your target but also of the area beyond it. Bullets can penetrate through targets and travel significant distances, so understanding the entire shooting environment is vital.

STEP 1: Eject the Magazine

Utilize the magazine catch to eject the magazine from the pistol. This step ensures that the firearm is not loaded from the magazine, establishing a clear starting point for the field stripping process.

Step1 - Eject the Glock Magazine
Step1.5 - Eject Glock Mag

STEP 2: Cycle the Slide

Cycle the slide of the pistol several times. This crucial action serves a dual purpose:

(1) It helps extract and eject a round if one is present in the chamber and (2) it provides an opportunity for a malfunctioning extractor to engage a cartridge if it is still chambered.

Step 2 - Cycle the Slide

STEP 3: Lock the Slide to the Rear

Engage the slide catch lever to lock the slide to the rear. This maneuver grants a clear view and access to the chamber, facilitating subsequent inspection and disassembly steps.

Step 3 - Lock Slide to Rear

STEP 4: Open Chamber & Magazine Well Visual Inspection

Conduct a visual inspection of the open chamber area of the pistol, checking for the presence of ammunition. Turn the pistol over and inspect the magazine well opening to ensure no rounds are present.

Step 4 - Inspect Chamber
Step 4.5 - Inspect Magazine Well

STEP 5: Physical Inspection of the Chamber Area

Physically inspect the chamber area of the pistol by carefully using your finger to ensure there is no round present in the chamber. This tactile examination adds an extra layer of assurance.

STEP 7: Return the Slide into Battery and pull the Trigger

Allow the slide to close on an empty chamber, preparing the pistol for the next steps in the field stripping process.

With utmost certainty that the gun is in a clear and safe condition, point it in a safe direction and pull the trigger with an empty chamber. This step is a crucial safety measure before proceeding further.

Step 7 - Return Slide into Battery

STEP 8: Retract, Unlock, and Remove the Slide

Retract the slide roughly ¼ of an inch and press the slide lock lever down. Releasing the Glock's slide while holding down the slide lock lever will enable it to "Slide-off" the front of the frame.

Step 8 - Retract the Slide
Step 8 - Unlock the Slide
Step 8.5 - Remove the Slide

STEP 9: Remove the Guide Rod Assembly

The guide rod assembly, with the spring attached, can be pulled up from the rear and removed from the slide with ease.

Step 9 - Remove Guide Rod

STEP 10: Remove the Barrel

Without the guide rod assembly, the barrel can move freely through the opening at the front of the slide.

Once the chamber clears the breach face on the slide, lift the barrel up by the chamber end and slide it up and toward the back of the slide for removal.

Step 10 - Barrel Removal

Reassembly and Function Check

Now that your Glock pistol has been successfully field-stripped, you can proceed with careful cleaning, maintenance, and inspection.

Glock Pistol Reassembly

Reassembly is a straightforward process, involving reversing from Steps 11 to 10 and then carefully sliding the slide assembly back onto the frame of the Glock, pulling it completely to the rear.

After reassembly, perform a meticulous function check on your now reassembled EMPTY Glock pistol.

Ensure the gun is empty by cycling the slide several times on a clear and empty gun before pointing it in a safe direction and pressing the trigger straight back.


Disassembly, Maintenance, and Inspection

Disassembling, maintaining, and inspecting your pistol are essential skills that contribute to ensuring your Glock has a long and useful service life.

Undertake these tasks in a safe manner, paying close attention to your pistol’s condition and your work environment.

By mastering the art of field stripping, you not only fulfill your responsibilities as a gun owner but also empower yourself with the knowledge needed to keep your Glock in prime, reliable, functioning condition for years to come.
