Anyone have a techinque for changing the "cups", on the Glock Firing Pin

[george burns]

Other than prayer, do any of you guys have a way to get those cups back in, by yourself? That was the only time consuming part of cleaning the Channel or replacing a Firing Pin or Firing Pin Spring in a Glock.
Mine was , Hey honey could you stick these, little black things in that thingy, no the other way. LOL

Try drilling a hole the same diameter as the plastic sleeve on the striker into a block of wood big and flat enough to be stable.

Drill the hole deeper than the plastic sleeve.

Place the seimassembled striker, sleeve, and spring into the hole.

The dog leg on the striker will allow the spring and sleeve to compress while keeping the striker stationary.

This will free up one hand by holding the assembly vertical as you compress the spring in one hand and place the cups one at a time with the other under the compressed spring.

Then let the spring out gently.

The maritime cups are even worse.

Doing it all under a big clear plastic bag might also be a good idea.

I use Bwana's method with one addition. I wear a thick rubber glove on the hand I use to push down on the spring.

You can use the slide instead of making a separate device.

Once you've stripped the slide, place it on a tabletop/flat surface muzzle down. Now the back of the slide will act as a disassembly jig for the firing pin assembly.

Place the firing pin assembly in the channel backwards with the lug to the side of the channel cutout so it acts as a stop . Now you can grasp the spring below the cups and push down. That will take the pressure off the cups and they will fall out or can be easily removed.

Some things to keep in mind.
The cups are small, dark colored and lightweight. Lose control of the spring during assembly/disassembly and the little plastic cups will fly a long way at high velocity and won't make much noise when they it. They are hard to find.

You may note that one end of the firing pin spring looks different--some do, some don't. If one end has several coils that are very close together, that end goes forward, against the firing pin cups.

Try to line up the separation between the firing pin cups so that it doesn't fall directly on the actual wire end of the spring during reassembly.

^^^What he said. That is the method Glock recommends. The only thing I might add is that if you secure the slide in a protected vise, it makes it even easier as you are not trying
to control the slide slipping away as you apply compression to the striker spring.
