What is the best .45ACP for concealed carry?

One of my friends carries a Kimber Covert 1911 with night sights and Crimson trace=) I wish I could afford a gun like that but really for concealed carry the weapon should fit your build. He is like Jason Statham so he can pull it off. I ussually opt for compacts over subcompacts because they are more concealable and actually fit my hand really well. I think for .45 ACP though you should just get a 1911 or one of the new polymer guns that have 15rd mags in .45ACP=)
