I wouldn't be looking at full size if carry is an option unless you live somewhere darn cold or wear a suit most days. I'd trade that G-17 for the G-19 (or equivelant). You lose nothing in terms of accuracy and it does carry better. As far as a 1911? Its a nice gun (I have a hi-power which is almost the same design), but I don't like a manual safety on an SD piece. Others disagree and thats fine, its just an individual thing. The Colts have been around for a hundred years for a reason, but for civilian concealed carry, I personally prefer a DAO pistol without a safety or a revolver, preferrably in .357
