I have owned both Colt's and Kimber's, I have had a Remington Rand 1911, 3 Colt Government's, 1 Gold Cup, 2 Detonics Scoremaster's, 4 1911 STI's and 2 Kimbers. I have a Kimber Tactical Custom II and a Kimber Super Match II, both purchased new and have never had any reliability issues so far, they shoot whatever I feed them, no feeding problems whatsoever, I've never had any problems with either one. When I had my Colt Gold Cup it was very fussy over what I could feed it, it worked great with 230 gr RN as most of them do, but 200 gr SWC were another story, switched to a Centaur Systems bull barrel with compensator and never ever had any issues with that gun.
Just my view of Kimber vs Colt. There will always be good and bad whatever you want to compare, but I would never take a box stock Colt over a Kimber.
