Personally
...
If you like the style, grips, and safety release, and a gun technically designed to be carried cocked and locked, then I would go for a Colt Commander in 45cal.
Perfect size, and thin, for both accurate and CCW use, along with a history of doing the job.
Personally, I'm going Sig P220R, as I like no safety, decocker only, and usage of it, without sacrificing a good 2-hand grip, while it is loaded with one in the chamber, full mag below, and hammer down, in DA mode, while a manual drawing the hammer back to SA mode is clean and easy, or pulling it thru a DA mode to fire straight-away is comforting, for me, in that it is not cocked and locked, which I personally would not be comfy with carrying like that, along with, holding down the safety release to fire is also, not a natural feel, but something that has to be learned/acquired movement with your thumb and, is not my cup of tea. But thousands have, and do, love it so.. and I can't argue with that fact.
IMHO, good luck in your choice of 1911
