I will probably be struck by lightening for saying this, but if you dont know what 1911 is good for ccw, than I suggest carrying something besides it. Glock, XD, M&P. This is no diss on you, but 1911's are heavy, more uncomfortable, (realize I put more, nothing is comfortable.) and really unless you are really familiar with a 1911 and shot one a million times it is not the best for someone who isn't a gun expert. It is my opinion that like a J-frame S&W that a 1911 should only be carried for ccw by people who shoot alot and shoot 1911's.
But look this is all my opinion. 1911 is the all time greatest gun, but it is a gun that shout be respected. It is not a dummy gun. And most times, unlike a Glock\polymer wondergun, the 1911 doesnt run better the more you beat it up. You need to maintain it, understand it, love it.
This is all for ccw only. If you want one to shoot and have fun with then great buy a 100 of them, but you must remember you are trusting your life to this if you will be carrying it. I would never buy a backhoe to dig a hole cause I cant operate one, but i will buy a shovel.
