I, also, have to back up Glock and Beretta. And, of course, if you've got the money, you can NEVER go wrong with Sig. My Beretta has a few thousand rounds through it and not a single hiccup. The Glock I own is in .40 s&w, but Glocks have always been reputable for their reliability, and I can attest to that personally as my Glock has a few thousand rounds through her as well. I've only had one jam with my Glock, and that was when a buddy's girlfriend had a low grip and limp-wristed it. Another over-looked firearm is the EAA witness. I have an Elite Match in .45, which isn't meant to be a carry gun, but their compact and polymer models are great carry guns, and are reputably reliable as well.
