I had an Ultra Carry 2 and it felt pretty good. The bull barrel was very nice and very accurate for such a short 1911. It was nice to shoot and mine only malfunctioned two or three time and that was when I was breaking it in. I was trying to get my hours worth at the indoor range so I had lots of mags and went through 300 rounds of WWB in about 45 minutes the only thing it did was fail to go completely into battery and that was when it was very very dirty so I blame it on that. That was the good.
The bad: The steel that Kimber uses is questionable. I sweat a lot at work and with in a couple months the beavertail safety had lots of surface rust on it. I cleaned it and oiled it well, and the next thing I know the beavertail is rusting even worse and now the hammer is rusting on the side that touching my side. I don't want and expensive carry gun that I have to baby and clean all the time when my cheaper MilSpec Springer doesn't have this problem. After owning the Kimber, I know I don't care for aluminum framed 1911's, I don't like their steel, I don't like the fact that they use a plastic mainspring housing. Was nice to shoot, nice trigger, and very forgiving on recoil....but I will probably never own another Kimber again.
ETA: Also the safety was a let down. It was big enough but it didn't really feel right to me. It didn't have that nice "snap" when the safety was switched on/off. It was just kinda sloppy...IMO
