As with rifles, the key to it is the loads themselves. Avoid light-bullet loads with too much slow-burning powder, and you should be fine. They tend to sandblast the forcing cone and topstrap, and accelerate barrel wear. Use heavy bullets and mid-range powders, and the gun will likely outlive you.
I carry a Smith & Wesson Model 10, that I have put almost 52,000 rounds thru in the past three years, and while the rifling is getting a little thin, the forcing cone and topstrap are fine. I shoot a plated 158-grain slug (soft lead core) over a stiff charge (barely +P) of Unique, and I expect to get several more years of use from it, maybe more. The only thing that has needed fixing was a firing pin, and the gun was back in service in a few days. No frame stretching, no sandblasting. And I have no idea how many rounds it had fired before I got it, but the holster wear is atrocious, and I doubt it got cleaned very often. I may push my guns by shooting them so much, but they get cleaned often, and are kept well lubricated. A dirty gun will wear itself out a LOT faster than a clean one. Hope this helps.
