Bought a new Kahr PM9 a month or so ago. I've only taken it out a few times, but instead of it becoming more reliable it is becoming less.
The problem is the slide not fully going into battery. The recoil spring seems to get considerably weaker in the last 1/2 inch of travel as the slide goes forward. The first time I went shooting I used only CCI Blazer ammo. I had a few failures to go into battery. I blamed the newness of the gun and possibly the ammo. The manual did recommed a 200 round break in. Most of the failures occured with the extended mag, and usually happened on the last round in the mag.
This last trip to the range the gun worked great for the first 30-40 rounds or so. Corbon 115+P, Speer Gold Dot 124+P, and Federal American Eagle FMJ. Then, after about 40 rounds (of Fed AE) as the gun started to get dirty, many failures to go completely into battery. Sometimes just a hair out of battery, not enough to disable the trigger, so the gun would still fire. This doesn't seem to be a problem when the gun is squeaky clean and lubed, but it seems after just a few rounds the combination of the spring tension being weak as the action is almost closed combined with the some minor fouling is causing this problem.
Anyway, I have fired about 400 rounds through the gun. Anyone else have this problem? Is Fed AE simply really dirty ammo? Should I keep going with more rounds, or send it back to Kahr?
Thanks.
