UPDATE...I found the missing spring!! It was in the same area (on my carpet) that I had looked over at-least 5 times...(I'm thinking that one of my cats was playing tricks on me.). Anyhow, I think I will order a Wolff spring kit, just in-case... Thank-you all for your suggestions! HELP!!!! I lost the Firing Pin Safety Spring to my Glock 21 earlier today while putting my slide back together, and I CAN'T find it. Does anyone have one of these little springs that I can have or buy? This is the little spring that fits inside the firing pin safety plunger. Wanna kill these ads? We can help!
