Well, Kimber thought they could improve upon John Browning's original 1911 design. Various gun companies have been trying to do this ever since 1911, and it has NEVER worked. Kimber is no different.
However, if you want to spend 1200 on a gun that is not a reliable as one a 1911 half the price, then go for it. Better not carry that sucker though.
IMO, if you are going to spend 1200-1500 on a 1911, go with a single stack STI, or do what I did. Buy a Springfield GI, and send it to Cylinder and slide, or buy ther enhanced R and D version, directly from them.
Kimber's may shoot most of the time, but for me that is not nearly good enough.
Just to lend a little credibility to my statement, I am a certified gunsmith, and regularly compete in IPSC, limited 10 division, and have a wide array of 1911s. Just my 2 cents of course. But, I do speak from experience.
