My first CC pistol was a gov't model 1911. I carried it IWB in a Theis holster for a few years. IMHO, the 1911 presents a nice, slim profile with a lot of rounded edges, which is good for carry. It's heavy, though. That was really the deciding factor that made me switch. If you don't mind the weight, a 1911 makes a great carry pistol. Personally, I've always liked the idea of a polymer 1911, but it does not seem to be an idea that has caught on, nor have I ever seen where someone has really put one through its paces to test reliability.
(Are you listening, Rock River? Just send me a Poly 1911 and I'll gladly wring it out and write it up!)
Believe me, I would LOVE to have a lightweight commander. And a BHP. Unfortunately, my budget will now allow either without selling something (or a couple of somethings).I don't have one but if you *almost* like 1911's for carry let me suggest you try a lightweight commander. Lighter and smaller and thus easier carry.
IMO an even better metal carry pistol is a Browning HP. I Do have one of these that's been thru the C&S shop. Thinner than a 1911 with more capacity. I bought one for carry but have since reconsidered since I like it so much and the replacement cost is more than I can afford these days. An even nicer option is the lightweight short slide version but then even more costly(and rare) these days.
These days I'm relegated to carrying tupperware pistols.
