Here's a review on a Pro Carry II and the problems it had on the range. At least it was a fairly simple (and also familiar) fix.
Very disappointing, but not surprising. My Pro Carry II did not have that problem but my TLE II did. If you have a 1911 and have failure to extract and stove-piping and the like issues, try a new extractor first.
Once I did that and swapped in some other parts my 1911's have worked great with excellent reliability. However... it took a bit of futzing. But since I got them at a very good price used I feel okay on the financial side.
However, I don't think it's worth buying a Kimber new.
