I also own three Kahrs, a PM9, a CW380 and a CW45. I don't recall if the 380 didn't hiccup once or twice, but the 45 and the 9 have been pretty darn good. The PM9 is a contender for one of the smallest 9's going (or maybe not, who has surpassed it in weight and size, seriously, I don't keep up on that?).
I just know that I really like mine and have had it for a good while. If I pull the trigger on that gun (PM9), it is going to go bang and it will do it again, etc...
The 45? I got that after I dumped my 30S, which just felt too darn fat for me. I only have room for one fat **** in my jeans waist band...
The 380 works, and is smaller than my LCP, and is ...sexier.
Now, understand, I GET that other people have Kahrs that don't work, me, if I'm just lucky and happen to have three that work? Well, fine.
Hey, OP, also; it looks like your gun has a stippled grip, did you buy it used? Or did you do that right after you got it? If the gun was used, did someone screw with it? And finally, after you got it un-stuck, did you look really close to see what (if any) got gouged up or anything on the slide/frame rail interface?
