I bought a new PPK yesterday and as with all my firearms I tear it down and check things out. I also watched a couple disassembly videos just to get educated. So as I was inspecting the slide I noticed the firing pin spring was binding near the breech face. No matter what I tried I couldn’t get it to seat without being cockeyed. So I removed the safety lever and took the spring out. What I saw was that it was larger at one end than the other? Is that normal? It’s causing it to bind before it makes contact with the back of the breech face.
