Well, first off let me start by saying that I'm a die hard 1911 fan, but I'm considering buying a plastic gun here and I don't know nearly as much about either the HK or the Glock. The models I'm interested in are the HK USP .45 or the Glock 21/30 in .45. Any reason why I should pick one over the other or should I just stick to the 1911's? Any thoughts would be appreciated.
