1911 Cracked Firing Pin Stop

While cleaning my SA milspec 1911 the other day, I noticed the firing pin stop had a hairline crack in it. Is this normal for 1911s? I plan on ordering a new one from Wilson combat, but should I order an extra one in case it happens again? Installation seems fairly easy.

Never seen that before. Do they use investment castings or sintered metal on their stops?

I believe it is a MIM part. It doesn't look forged. I bought it used but from what I saw when I first broke it down after I bought it, it looked like it had barely any rounds through if any. I've only put about 800 rounds through it.

I put a EGW stop in my Springer. Flat on the bottom the way JMB designed it. They do take a little fitting though.

Thanks from seagiant and High Hat

Thanks sbird. Ill take a look at that as well. I did some research on this and it appears its not that common and if it does happen, the round count is in the tens of thousands if not 100s of thousands

Yeah I have seen it before. All parts can break of course and even great quality replacement parts with enough use on them, if it is your main defense or SHTF handgun I would get a Wilson bulletproof part, and have a spare with a couple other choice parts, but that's just me.

Usual spot to crack. If you didn't notice it then it would crack on the other side. Had one do the same on mine. The next one I got, I used a round needle file to the corner.

I'd buy 2 and a titanium firing pin. Got to shed the weight since summer is here.

Can you say "broken"? Here's a firing pin stop a fellow discovered recently when his pistol was experiencing malfunctions that indicated the extractor was bunged up. Upon disassembly he discovered that only the top half of the FPS was still in the pistol. What was happening was that the extractor was clocking a lot and dropping the empty cases as they were being extracted.

I really hate titantium firing pins because they require excessively heavy mainsprings to light off primers. Any that I run across get tossed in the trash and replaced with steel ones, The heavy mainsprings get replaced with 18lb - 23lb mainsprings.


Thanks from seagiant

Ouch. I'm sticking with the regular firing pin. Also going with the if it isn't broke, then don't fix it theory.

Steve I'm right down the street in Bethlehem. Nice to see a fellow Lehigh valley member around.

They same the 90% angle causes the stop to creak in that area. Having put several rounds down the pipe I have changed the firing pin stop twice already. I keep spares in the garage since I own more than one version 1911. I have bought them over sized so I can hand fit them and that's only because I like to tinker.

JB, I'm not sure if this thread pertains to your pistol. It's how I got educated about my older Mil-Spec.

Thanks for the link. Gave me a few ideas on what I can do to improve the gun I have now. Mine seems to be a newer model milspec. I have the angled serrations on the back of the slide. I checked underneath the slide to see if I could find the Brazil stamping but did not see it.

Happened to me with a series 70 Colt. Upper half stayed put and got thru the match with it.
