I finally managed to test some self defense loads through the Kahr PM9 this weekend. I've taken it to the range a half dozen times or so with that intent, but never got around to it. I tested the same four loads as I did for the P30.
Despite the little blaster's 10 yard accuracy, it is not for self defense at ranges of 25 yards or more; my five shot groups (if you can call them that) were tough to keep on a sheet of 8 1/2" x 11" paper with all of those loads, fired slowly off sandbags. I shot five of each, except the HSTs of which I fired ten. That is the load for that gun, which conveniently is the one for the Glock 26 as well. Perfect.
Here's a rundown on velocities out of the PM9's 3" barrel:
124 grain Speer Gold Dot +P
- Ave 1,133 fps
124 grain Remington Golden Saber Bonded +P
- Ave 1,062 fps
147 grain Winchester Ranger-T
- Ave 926 fps
147 grain Federal HST +P
- Ave 974 fps
There were no stoppages. All of these rounds were unpleasant to shoot from such a little gun, with the Ranger-Ts being the less painful. None of them were any more accurate than the other, and none of them hit right to point of aim, so I should have fired them at 15 yards for that. Too bad. One day I'll put night sights on the gun, and then I'll check those loads and hopefully some other ones for accuracy at 15 yards and post my results.
