I bought a S&W 22A when my kids were getting into their teens and we shot over 110,000 rounds through the gun but it had many parts replaced over the years, including the frame. Firing pins broke regularly every 20,000 rounds but the gun maintained its accuracy through all that. We just have about 10K through a Ruger MkII but I have about 30 to 40k through a Hämmerli International over the years and I got it pre-owned. My favorite Korth .22 should also be in the 30 to 40K range.
The Colt OMM of my old gun club had timing problems after around 50 to 60K rounds.
