Upgrading the safety plunger on the Glock can make the trigger smoother and lighter by reducing friction. The LS Titanium safety plunger is shaped differently than the OEM safety plunger. The LS is more rounded and polished plus it has a Titanium Nitride coating which is very hard and has more lubricity than steel.
Replacing the safety plunger is very easy. I did my Glock 22 over the weekend and it took about 10 minutes.
Here is the disassembled G22 slide. Not a whole lot of parts involved. It also gave me a chance to really clean the slide good.
You can see the OEM steel plunger next to the LS Titanium plunger. The OEM plunger has some tool marks on it and is not polished. The LS plunger is polished and has no tooling marks whatsoever. It is a much higher quality part.
It is a simple procedure to replace the safety plunger. Here are the basic steps:
- Unload firearm and make safe
- Remover the slide
- Remove the recoil spring assembly and the barrel
- Use a small punch to push down on the plastic striker spacer sleeve to releave pressure on the slide cover plate
- Push the slide plate out and remove
- Remove striker/spring assembly and extractor depressor plunger assembly
- Push the safety plunger down to release the extractor
- Now remove the safety plunger
- Put the spring into the LS Titanium plunger and seat into position
- Replace the extractor
- Insert the striker/spring assembly and the extractor depressor plunger
- Start the slide cover plate into position
- With a punch, push the striker spacer down while sliding the slide cover plate in
- Now push the extractor depressor plunger assembly down with a punch until you can slide the cover plate into position and it snaps or clicks
