I have a Kimber Custom 4" compact. It's ~12 yo, all alloy frame. Can I shoot +P rounds on an infrequent basis? I have recently replaced my main spring & firing pin springs with new wolf springs. I'd like to buy a box of 255g double tap/buffalo bore +P rounds for woods carry. I would want to put a mag or two down range just to know what to expect and then load up a mag that would only be carried on rare occasions. Is this safe?
