Not impressed enough with mine to recommend. Several failures in 400+ rounds, but does seem to run ok now. Not that I wouldn't trust it to get 7 off, but just not impressed with the quality of the pm9 to trust it to SHOOT it enough to carry with confidence. Poorly finished/molded frame quality (not so much worried about looks on the outside, but the working internal surfaces), and much softer polymer than that of for example GLOCK.
And this is a point of some disagreement- but it was recently quoted in a gunrag that the life expectancy of the pm9 is 6k rounds. The author even said Kahr admits as much. According to Kahr, this is a mistake, and the mag will print a retraction next month. I'll be watching (will probably find it opposite a full page color ad for the p45
). I trust the gunrag about as much as I trust Kahr (little to none), but I just think about who has the greatest motivation to spin that little (alleged) admission the hardest, since someone is obviously lying. Plus considering that the author said that in context of PRAISING the pm9 as the model that "owns" the entire subcompatc class, gives the statemnt more credence. And after weighing the overall quality of the pm9, I would not disbelieve the statement. I owuld only recommend a pm9 if you are good with "Shoot a little, carry alot." I am not.
But it does have it's strong points. PM9 is one of the best firepower:size/weight ratios out there. So flat, so slim. And very shootable, very accurate. While the plastic frame is imo less than accpetable, the slide is very well made/finished. It is true that once broken in, it becomes a whole new gun, in that you can take it down with only your finger on the button, and the slide slicks up considerably. I don't like the long trigger reset and pull, but it is a light, and very smooth trigger. But if your k9 is an elite, you are already familiar with the pm9 trigger (all polymer kahrs have the elite trigger).
My advice is to stick with your k9. If you need something a little shorter in length and height (though not much in the way of weight), then make it a mk9. Kahr steel >>> Kahr plastic imo, ymmv.
