I've got a Kahr PM9.
Semi random comments:
It is a 9mm.
After a break in period (pretty frustrating) of 200 rds. or so, it's been 100% reliable.
Even with standard factory ammo, it's got some controllability issues. I added something called an "A-Grip" (adhesive wrap covering) which helps a bunch. Also replaced the mag floorplates with Pearce grip extenders.
I pocket carry it in a DeSantis Nemisis holster. Jeans, shorts, Dockers , slacks, it conceals just fine. You can take it places you might not take another pistol.
6 in the magazine, one in the chamber. They do come with a slightly higher cap mag, but they stick out like a sore thumb.
It takes great concentration to get acceptable accuracy, say, all shots in a
4" target at 7 yards.
It wasn't cheap.
These have been my experiences.
