Why Field Strip Your Glock?

Field stripping your Glock allows you to:

  • Clean and lubricate internal components

  • Inspect for wear and damage

  • Ensure reliable performance

Safety First

Before you begin, always prioritize safety. Ensure you are in a safe environment and follow these preliminary steps:

Unload Your Glock:

  • Point the firearm in a safe direction.

  • Remove the magazine by pressing the magazine release button.

  • Pull back the slide to eject any chambered round.

  • Visually and physically inspect the chamber to confirm it is empty.

Clear the Work Area:

  • Ensure your work area is clean and free of distractions.

  • Have all necessary tools and cleaning supplies on hand.

Steps to Field Strip a Glock

Follow these steps to field strip your Glock safely:

Check the Chamber:

  • Double-check that the chamber is empty. Pull back the slide and lock it open. Visually and physically inspect the chamber and magazine well to ensure no ammunition is present.

Release the Slide:

  • Release the slide by pulling it slightly back pressing down on the slide stop lever and let the slide go forward slowly.

Dry Fire:

  • Point the Glock in a safe direction and pull the trigger to release the striker. This step is necessary to disassemble the slide.

Pull the Slide Back:

  • With the Glock pointed in a safe direction, grasp the slide with your dominant hand. Pull the slide back about 1/8 of an inch to release the tension on the slide lock.

Depress the Slide Lock:

  • Use your non-dominant hand to pull down the slide lock lever located on both sides of the frame. Use your thumb and index finger. While holding the slide lock lever down, push the slide forward off the frame.

Remove the Recoil Spring Assembly:

  • Once the slide is separated from the frame, turn it upside down. Gently compress the recoil spring assembly and lift it out of the slide.

Remove the Barrel:

  • Lift the barrel slightly and pull it out of the slide.


After cleaning and inspecting your Glock, follow these steps to reassemble it:

Insert the Barrel:

  • Place the barrel back into the slide, ensuring it is properly seated.

Reinstall the Recoil Spring Assembly:

  • Compress the recoil spring assembly and insert it back into its slot on the slide, making sure it is seated correctly against the barrel lug.

Reattach the Slide to the Frame:

  • Align the slide with the frame rails and push it back onto the frame until it locks into place.

Function Check:

  • Perform a function check to ensure the Glock is assembled correctly. Rack the slide several times, dry fire, and check for proper trigger reset.

Maintenance Tips

  • Regular Cleaning: Field strip and clean your Glock after each use or at least once a month if not in use.

  • Lubrication: Apply a light coat of lubricant to the key friction points, including the rails, barrel, and recoil spring assembly.

  • Inspection: Regularly inspect for signs of wear, cracks, or damage. Replace any worn or damaged parts immediately.


Field stripping your Glock is a straightforward process that ensures your firearm remains in top condition. By following these steps and maintaining your Glock regularly, you can enjoy reliable performance and longevity. Remember, safety is paramount, so always handle your firearm with care and follow proper safety protocols.
