I was looking at Kahr as well. The slide on the one I checked out would stick halfway when racking and releasing it. I put it back down on the counter, said thanks to the salesman and continued my search.
On another Kahr I looked at the slide release could not be moved while the slide was locked back and the slide action felt and sounded like an old washboard. Kahr wants you to cycle 200+ rounds just to get it to function properly. Good thing same doesn't hold true about new car brakes!
