First off, I've been a loyal and raving fan of Kahr since I got my PM9 in 2005, so this isn't a flame thread or anything like that. I'm just expressing my frustration with the sudden demise of the formerly reliable gun after 5 years and several thousand rounds and, even more so, Kahr's seeming lack of care with fixing the problem (granted Ian is no longer there - he was the helpful one). In any case it started recently when I suddenly couldn't lock the slide back. After trying a few of their suggestions, including clipping a turn or two off the recoil spring (which to me is totally unacceptable in a carry piece), they agreed to take the gun back for service. It came back with, you guessed it, the end of the recoil spring clipped! They also replaced the slide lock and magazine catch. Tried to lock it back - VERY stiff - but I could do it so fine. Off to the range, 100 rounds with zero failures. Back again a week later and another 100 rounds with zero failures. Nice! I was ready to put it back into my carry rotation, until...... I broke the gun down for cleaning and lots of black plastic shavings fell out. Sure enough the right-side polymer frame rail, directly above the trigger, was chewed up and thinned out to half the original thickness. Not only unreliable for carry, but unsafe for shooting if you ask me. I contacted Kahr again. Their reply? "This is normal!" WHAT??? Sorry guys but break-in happened many thousands of rounds ago! At this point I'm very disappointed with Kahr and afraid that I have an expensive paperweight on my hands. In any case I rarely carry it anymore anyway because I can conceal my G27 almost as easily, but still, I want something to carry when I'm shooting the 27 at the range, or in very light summer clothing when pocket carry is in order. As much as I've loved the PM9 and as much as it's the perfect ultra-compact carry piece, I'm not about to go off and buy another of their overpriced guns after I feel like they screwed me on this one. Anyone else have similar experiences or any suggestions?
