I bought a new 9mm stainless Ultra Carry II about 2 years ago, and I will not buy another Kimber. Right out of the box it was prone to stovepipes and failure to eject, so I sent it back for repairs. When it was returned to me, it worked fine but not for very long- maybe 200-300 rounds before it stopped fully extracting the spent case from the chamber, causing a jam with the follow-up round in the mag. It's been sitting in my safe collecting dust ever since, until I find the time to make another call and send it back for additional repairs. Once it's fixed again, I will promptly head off to my lgs and trade it away for something I can actually use.
The general consensus regarding Kimber is that they tend to be hit-or-miss as far as quality goes, and mine unfortunately is a miss. When it's working properly it's a fun gun to shoot, and it's very, very accurate, but I don't consider it a very reliable gun.
