I had a chance to take the CM9 tungsten out and ran fifty rounds of mixed 9mm I had sitting in a bag through it.There was some 115gr, some 126gr and some 147gr all mixed up together and all of them ran fine with no problems of any kind. To start with i simply shot a paper target at 7yds, 10yds, and 15yds. It grouped all within the 4" bulls eye so I moved over to the rack of steel plates in that shooting bay next at 10,15, and 20yds. It ran all of those with no problems as well, the 10 and 15yd plates showed center hits so that's where it seems to shoot best for now.
I got it home and stripped it down to clean and inspect it and everything looks great. I'll run another through it fifty rounds through and call it good, I had forgotten how much fun a Kahr pistol can be.
