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