1. For normal cleaning, it is sufficient to dismantle the pistol into it's main component parts (see above graphic):
-Slide
-Barrel
-Recoil Spring Assembly
-Receiver
-Magazine

 

 

2. Glock pistols are stripped into their component parts in the following order:
-Remove the magazine (Fig. 1)
-Check for round in the chamber (Fig. 2 - check three times)
-Depress trigger (Fig. 3 - pointing in a safe direction)
-Remove slide from receiver (read following instructions #3)
-Remove barrel from slide

3. Removal of the slide:
a. Grasp the pistol in the right or left hand in such a way that four fingers rest over the slide and the thumb rests on the rear side of the receiver (Fig. 4 - make an O.K. with your hand and slip the beaver tail and end of the slide through the palm side of the O.K. hole)
b. Using the fingers draw back the slide no more than 1/16" (Fig. 5 - if you pull the slide back too far - you will need to rack the slide, pull the trigger and repeat this step).
c. Pull the slide lock downward with the thumb and index finger of the free hand (Fig. 5 - pull both tabs down at once to the bottom of the groove).
d. While holding the slide lock tabs down, push the slide forward and separate it from the receiver (Fig. 5 & 6).

4. Removal of the barrel:
-Push the recoil spring assembly somewhat forward with the thumb and raise it (caution - spring is under tension).
-Remove recoil spring assembly from the slide.
-Grasp the barrel on the barrel locking lugs, lift and push it slightly forward, raise and pull back out of the slide.

To reassemble the Glock pistol - carry out the above instructions in reverse order (although it is not necessary to pull down the tabs on the slide lock).
