My old interarms stainless PPK has logged a LOT of miles since I bought it about 30 years ago. It still gets used and carried. I'm one of the people who think you should shoot anything you're going to carry. Consequently mine has had thousands of rounds fired through it and looks it. Never once has it failed to operate when fed quality ammunition. I wouldn't change a rubmark or scratch for ANYTHING. I like it JUST like it is.
