My good friend who shoots higher volumes than normal wore out his S&W 442 on a steady diet of 38+P. It took about 10-12 years. He switched over to the S&W 640, after that.
He also wore out a S&W M&P 1.0 Pro series. One day, we were shooting at a 50 yard plate, and he said, “It is not possible with a polymer.” This is as I was ringing the plates endlessly with my Glock 19 MOS. He sent it to the factory and it had a stress fracture in the frame. He moved onto the 2.0.
I have a Ruger Mark II Target Competition and wore out the recoil springs after about 10, 000 rounds. I have over 30k in it now, and I acquired it used. No accuracy issues whatsoever. I clean it thoroughly every time.
