Could be! The problem is that I am a real believer in using one and only one platform in a combat handgun. I have a LOT invested in the 1911 in the form of holsters and mags. It would be hard for me to completely change platforms. The higher capacity is very attractive, though.
This being said you might want to try the XDm45. They have a 1911 grip with the 1911 grip safety and when you add the PRP trigger kit you also get a 1911 trigger. It's like owning a light weight high capacity 1911.
