Why would you only use a 3" if you knew the confrontation was going to be within 10 feet? My 3" Kimbers shoot just as well (if not better) than my 2 friends that shoot full size Kimber 1911's. They have even shot my 3” guns and agree that at distances out to 25 to 30 feet it shoots just as accurate as their full size models. I don't shoot IDPA, but I do shoot allot (more than 6,000 rounds a year). Carrying a full size (or even a 4" 1911) can sometimes be difficult. A 3" CDP is lightweight, easy to conceal and deadly accurate out to and beyond 25 feet.
