I have in the past carried:
My first army-issue sidearm was a 1911A1, the frame said Ithaca, no idea where the other parts came from, but it was at least 40 years old. It jammed a lot, but I kept the mags and tried them in other 1911s, army-issue mags just suck.
Beretta 92 -Army issue gun. I was assistant armorer, and we were alerted to keep count of rounds fired, because the mil-grade alloy slides were starting to crack after 10,000 rounds.
Taurus pt-92 -Double action failed, got rid of it.
Thompson 1911 -Horrible fit, finish, and reliability. Front sight flew out. Got rid of it.
S&W Sigma, first-generation .40 -Front sight fell out, feed ramp needed milling, had a squib with factory ammo. Got rid of it.
Colt 1991. No problems to speak of, it just felt cheap. I never had enough time and money to shoot it a lot.
Para-Ordnance P-12. Good enough piece, no problems, but I have never talked myself into really liking compact frames.
Glock 22 in .40 -Never had any problems, I just found myself lusting after the 1911 trigger and design, and I became realistic about the actual advantages of high-capacity vs single stack.
I now carry a Kimber Custom II, internal extractor. I added Hogue wrap-around finger-groove grips, and Novak night-sights. When I get around to it, I will add an arched mainspring housing w/lanyard loop, and drop the full length guide-rod. (My ceiling has a couple of pock-marks from when I have lost my grip on the plunger around the full-length guide-rod.) I carry it everywhere but work and church, I carry it as a sidearm whenever I'm outdoors. I have a Ciener .22 conversion kit for it.
I'm done. This is it. I will be buried with this one.
