Glock Field Inspection - Fully Assembled Pistol
Step by step instructions for field inspecting your Glock fully
Prior to performing any of these inspections unload the pistol
and do a safety check per procedure to ensure the firearm is unloaded
and safe to handle.
Slide Lock (3 steps to this inspection)
A. With thumb and forefinger, try to pull down on both sides of the
slide lock lever. It should not move downwards if the slide is
forward and locked in battery. This will let you know the slide lock
is present in "locked" properly.
B. Using the disassembly grip, move the slide to the rear
approximately 1/8 inch and pull down on both sides of the slight
lock and release. This verifies the slide lock will "unlock" and the
spring is operational.
C. With the slide lock lever fully engaged, point the pistol in a
safe direction and pull the trigger while pushing the slide forward.
The slide should remain "locked" and not move forward off the
Trigger Safety(2 steps to this inspection)
A. With the slide forward, action set and the trigger forward (ready
to shoot), press on both sides of the trigger and try to move the
trigger backwards. The trigger should only move slightly rearward,
not releasing the firing pin. Be careful not to press on the center
portion, trigger lever safety, of the trigger pad. This verifies the
trigger lever safety is present, operational and would prevent any
unwanted rearward movement of the trigger bar.
B. After making sure the pistol is unloaded, point it in a safe
correction and pull the trigger. When the finger depresses the
trigger lever safety, it should allow the trigger lever safety and
trigger to move rearwards and release the firing pin.
Recoil Spring/ Guide Rod Assembly
The recoil spring should be strong enough to move the slide forward
reliably to chamber cartridges even if the pistol is somewhat dirty,
dry or the ammunition is not perfect. With an unloaded pistol, point
it 45Â° upward and pull the trigger. While holding the trigger back,
pull the slide to the rear and release it very slowly. The recoil
spring should be able to push the slide completely forward and fully
into battery. This test verifies that the recoil spring is strong
enough to chamber ammunition despite less than ideal circumstances.
The magazine spring must be strong enough to feed all ammunition
reliably and be able to push the magazine follower up with
sufficient strength to move the slide stop lever up to lock the
slide to the rear when no ammunition remains. Insert and empty
magazine and pull the slide completely to the rear forcefully. The
slide should lock back every time without any assistance. This test
ensures that the magazine spring is strong enough to lock the slide
back when no ammunition remains in the magazine. It also checks for
proper operation of the follower and slide stop lever.
Firing Pin Safety Release (Free Movement)
When the trigger is pulled, the firing pin safety moves upwards and
clears the firing pin channel to allow the firing pin to move freely
to strike the primer with sufficient force. With an unloaded pistol,
point it in a safe direction and pull the trigger. Hold the trigger
rearward and shake the entire pistol. You should hear the firing pin
moving forwards and backwards. This ensures the firing pin channel
is unobstructed and the firing pin safety has been moved enough to
allow the firing pin to move freely.
