Default broken firing pin

I picked up my 629-4 today to put a few holes in some paper (The paper was asking for it !) I loaded it with some 240 grn swc drew a bead and squeezed the trigger, click no roar I opened the cylinder yea I put the bullets in the gun. I drew another bead on the target squeezed the triger, nothing on closer exam the firing pin was broken off. has any one had this happen ?? the gun wasn't dropped or used as a hammer. What a bummer I'm glad I had my 686 with me I was still able to punish that evil paper.

They do break sometimes. The older hammer mounted type seem to be a lot more durable, the new frame mounted ones seem more prone to break. But, both kind will break every once in a while.

A 629-4 should be a hammer mounted firing pin, not a FMFP. Based on what do "the new frame mounted ones seem more prone to break"? Not counting the C&S extended pins I haven't seen or know anyone who has seen a broken "new style" S&W FMFP. Have you?

Yes, but it's been a while. And I recall the failures were behind the "dry fire" controversy with the FMFP when they first came out. I don't think they are highly prone to break, but some have broken (don't know if they were steel or Ti). I also recall reading the earliest pins were MIM steel, but I am not dead sure how many of those got made.

I do remember clearly when SW first came out with the FMFPs, I called SW factory and asked one of their smiths if it was still OK to dry fire just to be safe. He replied something like it would take millions of hits to break one. As I recall, SW later reversed that opinion and said we should be using snap caps. Anyway, I do think the hammer mounted pins are more reliable from what I have seen but neither break very often.
