An Auto Ordnance from the early 80's (my first handgun, actually) and an old Springfield Armory. The AO is roundly considered to be a piece of crap. I've put probably 150,000 round though it, though, and it's shot OK. Most parts have been replaced at least once. I think I'm on my fourth barrel, and I'm pretty good at putting in a new spring kit.
I tend to just shoot the old military type 1911s. My uncle has a very nice tricked out Kimber. But I like the old, parked war model 1911 better for some odd reason.
