I'm interested in a .45 handgun..? which one is good?

I gotta agree with Andrew. I love 1911's and you can find a used one for a good deal (especially the GI or Mil Spec from Springfield, and Rock Island Armory makes a good gun too). I hate the way a Glock feels in my hand and again like Andrews said its polymer, which I don't have much faith in compared to steel. Don't know much about the USP though.
