The first thing I'd do is take some emory cloth and polish up the feed ramp. That may solve all his issues. Next would be mags. Kimber used to use Chip McCormick mags and they were hit and miss. I got lucky and got two that worked. But it didn't stop me from buying 4 Wilson Combat mags either.
For some reason, the feed ramp on Kimbers can be a little rough and that will cause the problem you're describing. A little emory cloth and about ten minutes of working it solved the issue on my gun.
