I bought my Kahr PM9 last weekend at a local gun show. I went to the range a couple of days later and shot 150 rounds. Decided not to shoot more because the barrel was fairly hot and the barrel thickness seemed thin to me, as compared to my EMP. I had 8-10 failure-to-feed in the first 50 rounds, not unexpected. Not a single failure 50 – 150 rounds.
I like it and believe it will be a great CCW. I'm headed back tomorrow to shoot another 150 rounds.
Mine came from the factory well oiled. I read that these guns need a generous dose of oil because of the tight tolerances. I oil mine again after 100 rounds. I believed it helped. Also I read in the manual that if you get a failure-to-feed (which is expected during break-in), don't pull back on the slide to release, rather, use the slide stop to release. That turned out to be good advice. When I pulled back on the slide to release, had problems from time-to-time. When I used the slide stop, worked perfectly.

Just got back from shooting another 150 rounds - Kahr PM9
One failure-to-feed. One failure-to-fire (pin didn't hit ignition cap hard enough).
I shot Fiocchi 115 Grs. FMJ ammo.
I wouldn't carry concealed yet ... not until and if I get 300 - 400 rounds with no failures. Will post again after another 300 rounds.
