shoot about 500 rounds, it should go away

Kimber's have such tight tolerance's that a good break in period is requirde sometimes to get things moving and broke in well enough I have the Kimber Eclipse Pro II and so far with 250-300 rounds so far so good

I hope you broke it down and cleaned it well before your first session. Kimbers come with a lot of lubricating gunk in them. Some times this stuff can get into places and cause malfunctions. Clean it out really well and use a light spraying of Rem Oil on the rails and moving parts once all of the gunk is gone. When racked, my Kimbers sound like a zipper being worked rather than like the metal ion metal of a gun racking on its loose slide.

If you have cleaned it or do so and still have the problems, run another 200 rounds down the pipe.

After 500 rounds of FMJ, and then 500 rounds of hollowpoints, to test for function, and break it in... when you're still having issues, just trade it for a modern gun... LOL

Just throwing salt...
