Don't get me wrong Do-man, I own a Kimber and think its a fine gun, but just ok for the money. It is more reliable than a factory Colt, but shoots mediocre groups and lays a pattern 3 inches to the left and 2 inches high at 15 yards with the factory sights (which are rather poor to begin with, huge gap). Totally unacceptable.
Other than the slide to frame fit, I don't see what is so remarkable. The arched mainspring and beavertail suck, the sights suck, the slide is ugly, the trigger has way to much creep and is too long, the finish is like chalk, MIM parts ect. ect. ......
What attracted me to the Colt was a 1991A1 I would rent at the range. Felt great in my hands, didn't have the B.S. doodads that Kimber seems to think people want (most tactical stuff is simply crap), and while not as reliable as my kimber, it retails for at least $150 cheaper.
Its cheaper, its the original, its more comfortable (imho), and most importantly YOU get to decide what "tactical" or "custom" extras you feel are necesary. Don't overpay, Colt has a better resale value too.
