I wanna like HK, I really do. I liked almost everything about The two USP's I owned. (45 tactical, and 40 full size) love the grip, loved the look, like the ergonomics, great quality. Just couldn't get past the trigger. Worst I've ever shot in a handgun. Bought the 45 tactical cause it was supposed to have a "match" trigger. Nope, still couldn't shoot it accurately for nothing.
Make sure it really has the match trigger. Dukeyjoe's HK .45 tactical with the "match trigger" wasn't. HK in Columbus corrected it for him. The triggers are supposedly easy to change out. I haven't seen the need to mess with mine. That said I did work on my Glock 34 trigger. All the other Glocks are factory stock and get better with trigger time.
