A post here about a Ruger MkII with 40,000 rounds through it with no parts failures got me thinking. I had bought a S&W 22A years ago as a cheap plinker, we have shot over 90,000 rounds through it and had bought it used. It had several parts fail; three firing pins sight rib integral claw broke (old style) recoil spring broke frame cracked around 60,000 rounds The hammer spring did set so much that no reliable ignition was possible around 60,000 rounds, too. The stud on the upper that connects the pistol to the lower was loosened twice, despite use of Loctite. A friend has a Hämmerli 208 which he has shot extensively in his younger years and has about 60,000 rounds through it. No parts broken or worn with the exception of the slide stop hole, it needs a bushing inserted or being staked now to reliably work the slide stop and hold-open function.
