I have owned 3 Kahrs. Yes, I'm aware of tap rack. It's one of the reasons I got rid of my Kahr. With a full mag of every JHP I tried, it would jam when I did a tap rack. Doing another tap would sometimes get the stuck round to feed - sometimes not. Thus a tap rack became a tap-rack-tap...yet another quirk with Kahr's manual of arms. A quirk that could add time to a situation where time is short.
Most trainers (self included) would advise consistency in training. If you only run Kahrs, then that's not an issue.
Enjoy your Kahr.
