GLOCK FIRING PIN SAFETY CHECK

Make sure that the firing pin safety is properly engaged by pulling the tang of the firing pin toward the rear of the slide (do not allow the firing pin to snap forward - ease it forward). Next, hold the slide in the palm of your hand, sights down, with your thumb pushing the tang of the firing pin forward. The firing pin should not protrude from the firing pin hole. If it does, the firing pin and firing pin safety should be replaced.

Assuring the firing pin is released by the firing pin safety - Method One
First make sure the firing pin safety is engaged and then hold the slide in a Muzzle Down position and depress the firing pin safety. The tip of the firing pin should move forward and be visible protruding from the firing pin hole. The firing pin may need to be pushed forward when the pistol is new, so that it will protrude from the firing pin hole.

Method Two
Depress the firing pin safety and shake the slide. When the firing pin safety is depressed, the firing pin should be heard moving freely. When the firing pin safety is not depressed, the firing pin should be nearly silent.

Please note that there could be more wrong with a firing system in a Glock than is outlined above. If you are having problems with your firing system, consult a qualified Glock armorer. The above information is only being presented as general information, it should not be performed by anyone other than a Glock Certified Armorer.
