How to Install Or Replace A Polymer80 or Glock’s Firing Pin Spring Assembly

Installing or replacing the firing pin spring in a Polymer80 or Glock pistol can seem daunting. It’s actually quite straight forward but you would never know it at first glance. I had to do some digging and want to share with you two videos that really helped me out.

Here are all the fun parts of both the firing pin and extractor plunger assemblies.

The top unit is the assembled firing pin group. The lower part is the Extractor Depressor Plunger assembly. I’m just showing the plunger because I had them together when I did the photo. You can leave the plunger alone.

I hope this helps you out.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
