PM9 sucks
I have to chime in on my experience with the Kahr PM9, er, rather my dad's experience with the PM9. My dad got his permit just a few months ago and then started shopping for a carry weapon. I decided to buy him whatever he chose, sorta as a long overdue birthday present/father's day gift/early Christmas present. I tried to steer him towards a subcompact XD or baby GLOCK, but when he got his hand wrapped around that tiny little Kahr, he was completely sold on it and could not be convinced otherwise.
We both did a little bit of checking on the internet and noticed that the PM9 had a few "teething problems" early in it's production, difficulty chambering the first round, random slide locking, trigger reset issues, barrel peening, etc. From what I read on this forum and several others, Kahr was pretty responsive at resolving everyone's issues and taking care of these quality/production problems. The specific gun my dad intended to buy had a serial number that was not listed anywhere within the batches with known problems. Kahr first introduced the PM9 in 2002, and this gun was manufactured in September of 2006, so we both figured that SURELY all the bugs had been worked out by now, right? Right?!? WRONG!
The PM9 manual stated that the gun should not be considered reliable enough for carry until at least 200 rounds were sent through it to break it in. My dad happily obliged and sent 200 rounds of WWB through it. About 2/3 of the way through, he began having trigger reset issues: the trigger would randomly fail to recock the striker when pulled. The occurance was so erratic, that you could chamber just 1 round and play Russian Roullette with it just as effectly as a revolver, were you to be so foolishly inclined to do so. My dad took it back to Gander Mountain and had the in-house Gunsmith examine it. Two day's later the gunsmith returned the gun, claiming that he shot 100 rounds without any problems and that nothing was wrong with the gun. Despite this, we noticed obvious filing that had occured to metal rails. Why this would be related to trigger reset was beyond either of us. Miraculously enough however, the trigger reset problem appeared to be resolved. My dad was able to put another 300 round through it without issue, and deemed it reliable enough to start carrying. This did not last long however.
Another trip to the range soon revealed other problems. The gun consistantly fails to properly chamber a round when a magazine is inserted while the slide is closed. This might have been a problem all along, but being new to autoloaders, perhaps my dad simply never noticed initially. Eventually though we both came to realize the only reliable way to chamber a round was to insert the magazine while the slide was open. I suspect this is partially due to the unique design of the Kahr magazine, which aligns the top round in the magazine at a different angle from the other rounds. IMO this is a really really poor design. Additionally, the slide would start locking part way through a magazine, and eventually the end of the trigger spring came down through a hole in the frame, viciously stabbing the trigger finger under recoil. Later that day when my dad was cleaning the gun, he noticed significant barrel peening had started. Nasty nasty stuff, to say the least. The barrel is self destructing and my dad made the decision right then and there not to put another round through it until someone looked at it. The plastic rails on the frame are also rough and ragged with lots of flash and loose plastic hanging about, despite lubricating in a manner more suitable to a 1911 than a modern polymer pistol. Also, there's no doubt about it, the plastic on this gun is much much lower quality than a GLOCK or XD. In the short 2 months that my dad had it, the plastic frame has receiver several nicks and indentations, some of which occured simply from laying the gun down on the range bench. My GLOCK26 on the other hand, which has seen more carry time, and more abuse, still looks like new.
All said and done, my dad has put about 650-700 rounds though it, and at the rate it's going, I can't see how it would ever reach the 2500-round service life as someone else stated. It's a shame too, when my dad read the article about the Walther PPS in the latest Guns and Ammo he let out a loud and resounding "DOH!" I read the article too, and it definitely seems like the gun that the PM9 should have been.
Anywho, we are in the process of trying to get in touch with Kahr to see what they can do about this mess. The gunsmith at the local Gander Mountain claims there is nothing wrong with the gun and refuses to assist us further. I wish I could recommend this gun, as it is a delightfully compact little booger that is still chambered in a decent caliber, and of course is American made. Sadly, it seems that quality control still isn't up to snuff with Kahr. I certainly hope, for the sake of Kahr's reputation, that they can resolve these issues. If it were me, I don't think I'd be able to trust it for carry and would probably cut my losses and sell after it comes back from Kahr and put the money towards a Walther PPS. It will be interesting to see what my dad does. Anywho, I just thought I'd throw my own/my dad's personal experiences with the PM9 out there for anyone interested. I wish whoever else buys one a whole truckload of luck!
