I dunno, maybe it's me- but I've been shooting my revolvers like there was no tomorrow for longer than I care to discuss, and I have never needed to buy a single part- if you discount one I managed to lose. I have never worn a hand in my Colts, and a couple of them certainly have several thousand rounds under the belt.
I have had to deal with worn pawls in Colt (and other) revolvers from other people. Mostly extremely worn and old police issue guns. They all could be stretched to specs. No biggie.
