ALL WORK ON GLOCK PISTOLS SHOULD BE PERFORMED BY A GLOCK CERTIFIED ARMORER - WITHOUT EXCEPTION.

  SAFETY CAUTION
The firing pin assembly and extractor depressor plunger are under tension. While removing the slide cover plate, place your thumb over the firing pin assembly and extractor depressor plunger to prevent these parts from ejecting while removing the slide cover plate.

To aid in the removal of the slide cover plate, place the muzzle end of the slide on a smooth, flat surface such as a table. Keep the slide in and upright position while applying firm downward pressure on the slide. With your free hand use your Glock disassembly tool to push the spacer sleeve forward (see figures 1 & 2).

Simultaneously, slide the cover plate down and off (Figure 3) - remember to keep the tensioned firing pin assembly and extractor depressor plunger from springing out. It is possible that the slide cover plate will require some additional downward force during disassembly of a new pistol. A thin bladed screwdriver may be used to start removal (don't force it).

Remove the firing pin assembly (figure 4).

Remove the extractor depressor plunger assembly (figure 5) consisting of: extractor depressor plunger, extractor depressor plunger spring and the spring loaded bearing.

While depressing the firing pin safety, remove the extractor (figures 6 & 7). The extractor may need to be pushed from the extractor groove by using your Glock disassembly tool in the rear of the extractor and lifting the extractor from the groove.

Remove the firing pin safety (figure 8). If the safety does not drop out of the slide; the slide may be tapped on a non-metallic surface to free the firing pin safety. Be careful not to lose the firing pin safety spring when removing the safety.

Before you disassemble the firing pin assembly, wipe the assembly with a clean dry cloth to remove any excess lubrication or solvent.

Pull down on the firing pin spring with the thumb and forefinger as far as possible to allow clearance for removal of the firing pin spring cups. Be sure to keep a firm grasp on the firing pin spring so that it does not launch itself and possibly cause injury or become lost. Simultaneously remove the two spring cups, then gradually release tension on the firing pin spring and remove it (figure 9). Now you can remover the spacer sleeve.

When reassembling the firing pin assembly, ensure that the small end of the spring cups are inside the firing pin spring.

Reverse, for reassembly. REMEMBER TO DO A FIRING PIN SAFETY CHECK AFTER THIS PROCEDURE.
