If I had it to do over again, I would probably get a full size Springfield Mil-Spec. I like my Colt, don't get me wrong, but the front sight has worked loose twice and Colt failed to fix it, plus the Series 80 parts are a pain to re-assemble. A full size isn't too hard to conceal, I have no trouble with my Commander and all a full size adds is 3/4" of barrel and slide.
If you've got a bit more cash to spend, the Dan Wesson Commander Bobtail is a nice-looking piece. Steel 1911's are heavy, but with a good holster and belt they're manageable. Just give yourself a bit of time to get used to it before you give up.
