With the help of this 3D Glock animation you should be able to handily disassemble and reassemble a Glock 20 with ease.
It doesn’t get any easier than this. Jay Xiong has created an animation that illustrates in the clearest of ways how to disassemble and reassemble a Glock 20.
With animation that highlights in momentary red the part you are working on, and a voice-over narration that explains each step in the simplest of terms, you really can’t go wrong here.
Working with the five major parts of the handgun, you will learn to quickly and easily remove each component.
One, remove the magazine by releasing the magazine catch. Two, check to make sure that the pistol is empty by performing a visual inspection with the slide pulled back far enough to view the barrel inside. If the gun is empty, then pull the trigger.
Three, place your right hand gripping the slide as illustrated in the animation, and place the fingers of your left hand on either side of the Glock on the slide locks. With your right hand, pull the slide back about a half-inch, and apply inward and downward pressure on the slide locks with the fingers of your left hand. The slide should now travel freely upon the receiver. Remove the slide from the receiver and set the receiver aside.
Four, remove the recoil rod found at the bottom front of the slide. Do this by squeezing the recoil rod and pulling it free of the slide.
Five, remove the barrel by pulling it out a bit from the center of the slide, pushing it into the barrel opening, and pulling it completely from the slide.
There, you should now have five main components of the Glock. To reassemble, simply reverse the procedure. Make sure that the recoil rod is facing the right way, and slide the slide back far enough to snap everything into place.
Thanks to Jay Xiong for putting together this excellent animation.
