I recently went over 3000 rounds on the PM45 I bought in mid-2008. Since there aren't that many posts about high round count Kahrs (and lots of questions about how they hold up) here's my sample of one: My PM45 is a great shooter and has been since day one. It has malfunctions only after 150+ rounds have been shot in one session, and a quick wipe and lube fixes it right up. I always clean it after I shoot it, use grease on the metal contact points on the rail, and have polished the feed ramp a few times using silver polish from the kitchen. Otherwise it gets no special treatment - just a lot of lint. Around 2400 rounds it started dropping the magazine uncommanded while firing. I ordered a new magazine catch spring and took the opportunity to get new recoil and striker springs as well. It went in the safe and my Sig took over as my carry gun. The magazine catch spring didn't help at all, and by now it was dropping the magazine every few shots. It dropped the 5 round mag. It dropped the 7 round mags I carry as spares. It did it strong hand, weak hand, with a buddy shooting it... It wasn't me. I like figuring things out myself, so next I ordered a new magazine catch. When it arrived I was disappointed to find that it looked exactly like the old one. (See pictures below. The top one is the old, the bottom is new). I went to the range figuring it would only take a few shots to drop another magazine. It didn't. I shot 200 rounds without a single malfunction. A week later I went and shot another 200 without a problem. This was mostly FMJ with a box of carry ammo thrown in just to make sure. I am amazed that the new part made such a difference. I guess it just shows how tight the tolerances are on Kahrs. My PM45 is back on my hip now. It's gone a little over 3100 total rounds. I'm going to replace the recoil springs every 1000 rounds from now on and get a new magazine catch at the first sign of trouble. I'll post any other problems if they happen. - Wilson More pictures: Wanna kill these ads? We can help!
