Every Kahr I have ever shot in rapid fire, while admittedly not being trained on the particular gun, I short stroke the trigger reset every elfin' time.
Slow fire shooting makes me want to love the gun. Rapid fire I think it could get me killed in a fast and close gunfight.
Admittedly I've never shot a Kahr rapid fire. But I believe the trigger is extremely similar to a DAO revolver. Just way smoother. I'm gonna try and get access to one soon and fire off some shots. I believe there's a local competitor who has a PM9 and he will let me try it out.
I'm jonesing for a pocket/ankle carry gun again. Never really liked my S&W 642... little palm stinger.
