I bought one in March of '15, and it wouldn't make it through a single magazine without a failure. Different magazines, same results. After struggling through a 150 or so rounds of various loads, including their own recommended factory loads, I replaced it with a Kahr CM9 and forgot about it. In February last year, I came across it and called Kimber about it. They sent a pre-paid label and off it went. When I got it back three weeks later, the ticket said the frame had been replaced as being "out of spec". It works fine now, with everything I've tried in it.
