Lots of the single stack 40's I see don't run very well, Kimbers included but not any more so than anything else. My belief is that the vast majority of the problems are magazine related. Good 40 magazines for a particular gun can be hard to find.

One thing that helps dramatically is to have the barrel throated for long loads and loading 40 at 1.235"-1.255", makes magazine selection less critical and nearly every gun will feed better.
