You gotta understand this - guns are like off road machines - the Jeepers hate the Hummers, the Glockenspeils hate the 1911ers, etc., etc., etc. It's all bullshiite. Stick with the best brands, (Glock, HK, Kimber, Springfield, Beretta, Sig, etc) and SHOOT 'em all. A lot. Then stick with the one that feels most comfortable to you and that you shoot the best. Be sparing with the modifications (again, like an off road machine) and it will be a reliable machine. I have an original COLT Combat Government in .45acp that has had the piss shot out of it. Untold thousands of rounds (yeah, get a Dillon reloading press) and it is as reliable and accurate and awesome as it was on day one. If pressed for a particular weapon as a recommendation, I'd have to side with the Wilson CQB as previously mentioned. Then do NO mods and just shoot it, and shoot it, and shoot it, and shoot it........
