I found it to be less than ideal for pocket carry personally. It has been put on "uber discreet IWB" duty for when I can't afford to carry anything more substantial.
Given my schedule, however, this means I carry it 90% of the time; Unfortunate for everyone but the PM9.
I still prefer J-frames for pocket & ankle carry. When I have to draw the PM9 from my pocket, the top of the slide sits an inch or so above the top of my hand, giving me more "width" which needs to come out of my pocket. The way I grip a hammerless J-frame (high), the gun that comes out is no wider than my fist. While the PM9 may print less due to its thin width, it still prints, and it looks more like a gun in your pocket than a revolver, with which the cylinder creates an unidentifiable lump of "something". The Kahr really shines for discrete IWB, crossdraw, or smart carry due to its width.
I've also been experiencing some "bite" on my ring and pinkie fingers, stronghand, while shooting. The short mag (6 round) isn't completely flush (like most guns) and can bite you a little depending on your grip.
Nevertheless, the power/bulk ratio is too good to get me to sell it. Having 14 rounds of 147gr. 9mm +P via a fast reload, in a package that I can conceal in damn near anything is pretty sweet.
P.S. You HAVE TO use the slide release to chamber a round. You'll also need to put 200 rounds through it for break-in, which I thought was an "excuse" until this gun. I had one failure on round #23 or so, but none since. I've never seen a gun change so completely in 200 rounds. They're really tight from the factory.
