I know that Kahr gets a bad reputation from time to time, so I wanted to post a positive review. I own a Kahr MK9 and it has been flawless since the day I bought it. I decided to buy a PM9 due to the much lower weight and for the Crimson Trace LaserGuard. I originally bought a Crimson Trace LaserGrip for my MK9, but due to the fact that I have a very early model, the grips don't fit.
Before taking the PM9 to the range, I gave it a thorough cleaning and lubed it very well. I racked the slide about 150 times to help speed things up. Installed the LaserGuard in just a few minutes and went to the range.
Shot about 200 Speer 115 grain TMJ without any issues at all. It took me about 25 rounds to correct some bad targetting and shooting habits. I was anticipating the recoil too much and kept on aiming the gun too low. I was all over the place. After calming down and adjusting the way I shot, everything was much better. I started shooting 2-3" groups at 25' and surprisingly well at 50'. I love the Crimson Trace now. Picture from 50' attached. I had a few shots that went out of the group from not keeping steady, but I think it will only get better with practice. Definitely more accurate than I ever dared hope from such a small gun.
Recoil was not as bad as I thought it was going to be, but definitely more than the all steel MK9. I defensive rounds from Federal (135 grain Personal Defense) and Speer (124 grain +P Short Barrel). They both were vey accurate. My hand was a little sore after the session. Now I'm just waiting on a Crossbreed MiniTuck to come in... and Crimson Trace to make a LaserGuard for my Kahr P380.
