Extractor tip on a Colt goverment model broke off on me. Don't know what caused it but I had shot the thing for 20 or 30 years on a regular basis. bought a new replace ment ad was off and running.
Happened to me, too, and I've told how the gun kept shooting normally all day. Resulted in my first "ND/AD" when I racked the slide and no cartridge popped out, so I pulled the trigger. No harm done, though, except to ego. Long time ago. Now I visually and manually check the chamber.
I keep an eye on thin metal disconnectors which ride in a groove on the side of the slide, though no problem so far.
I had a significant crack in the recoil spring fork on a Ruger Standard once:
(Thanks for the pic, MidwayUSA!)
Once again, the gun kept running normally and I didn't notice it until I stripped it for cleaning. Ruger sent me a new one for free. This was loooong before Larry Potterfield's hair turned grey.
Apparently, the pawl on my Model 19 is wearing, since the timing is getting a little sloppy. On that one, I split the forcing cone at the back of the barrel after firing (insert large number here) full-house .357 loads through it. (Apparently a not-uncommon problem with the 19.)
I finally installed a replacement barrel*, but I think I'm going to replace the pawl on it on general principles. Might put a new hand in it, too, while I'm at it.
I never replaced the recoil spring on any semi, although with all the .45s around, I'm toying with the idea of building a simple spring-testing jig** to keep an eye on their status.... stati?
