I am looking at getting a HK USP 40. After shooting it yesterday I was duely impressed with almost everything. I shot better with it than I think I ever have with a large caliber. The trigger pull was nice and it had good groups once I figured out how that one shot. My only dislike is the jump/kick. My one question is this...is it possible to get after market bullbarrel or any other for the USP? If so where can I get one?
