So, it's been a while since this trip to the range but I thought I would share this anyhow. I had bought my PM9 for CC use and I needed to break it in. I followed the prep thread over on the Kahr forums. I also added some grip tape to the grip as well as a grip extender to the 6 round magazine.
I wasn't too concerned about accuracy. I mainly wanted to make sure it cycled accurately. Ammo I used was some Federal FMJ. I went through 200 rounds and all of them cycled flawlessly except one. I had a FTF and the slide locked back. When I checked the chamber the round was nose down in the magazine. I ejected the magazine and reinserted it. Released the slide and it fired every round after that without any more failures.
I was aware of this issue before I went to the range. The issue is that you might have issues with the bullet catching the slide lever causing the slide to lock back and an FTF. I had checked and it looked like clearance was good on both the range FMJ and defensive JHP I have.
As such when I got home from the range I broke it down and filed down the slide lever ever so slightly. Now I just need to get back to the range to test it again to see if I get another failure. In the end my accuracy wasn't too bad since I wasn't focusing on that.
Here's the target from the first box of rounds. First half shot at 7 yards, 2nd at 10 yards.
Overall I'm happy with the gun so far. However, I've decided I need more magazines to take to the range. Two just doesn't cut it.
