I've had tons of jams with a 1911, some with .22s. If you find what the gun likes to feed, though, it will live happy. Most any auto will feed ball if nothing else. I clean my guns as matter of routine, carries even if they haven't been fired, once a week for those. I've had a few parts break like the return spring for the mag release in my Ruger P90. I might could have kept fighting with that one, but it would have made things real difficult.
I've had two stoppages of a revolver. One was a hammer mounted firing pin that snapped on a Rossi and one was a forcing cone that split on a K frame. The firing pin was fatal for the moment. I MIGHT could have fired a few more rounds in that K frame. I realized I had a problem as the cylinder began to tie up from the forcing cone binding it where it split at the flat at the bottom. That's a traditional weak spot, problem with K frames that is pretty much specific to them. And, this was a model 10 firing .38 wadcutter, too, not some super get down 125 grain .357 load in a 19. I think it was lead build up at the forcing cone that did it. I'm a little more diligent about cleaning the forcing cone on that gun now. I had to have it rebarreled.
