I tend to move around on what gun I'm carrying. In full size I have my choice between a Kimber Tactical Custom II, a Kimber Desert Warrior, a Kimber SIS Custom, a Taurus PT1911, and a Charles Daly. I also have full sized 1911's in chamberings other than 45, such as 10mm and 38 Super that I will occasionally carry.
The 2 that get the most use though are my Tactical and SIS.
