I bought a Kimber Super Carry Ultra about 1 1/2 years ago. It wouldn't feed reliably so I did the usual routine. I tried different magazines, and went through the "500 round break-in". It still wouldn't feed reliably, so I sent it back to Kimber. Almost 2 months later they sent it back to me, and it jammed on the first feed.
I took it back to the dealer, told them about the issues, and traded it on a Springfield.
