I have also been looking. They are very close to the 1911, I will add one to my collection soon. I currently have two Sig 45s, a 220 and 245. Both are great shooters, but the 1911 "look-a-like" really impresses me. Don't be fooled by thoise that insist parts are interchangable, they look like a 1911, but there are many differences. If Sig sticks their name on it, it has to be quality!
Only down side...............they sure are proud of them!
P.S. If I slip one in and the wife catches me, can I tell her I am just keeping it for you so you wife won't find out?
