The lighter the bullet weight, the lighter the recoil. Out of all the Kahr models, the PM9 is by no means any kind of a tack driver. It is basically a belly weapon that is intended for deep cover or concealment for close range. I've owned several Kahrs over the years and have only one real complaint, i.e., the rounds have a tendency to walk out of the magazines when not in the weapon. If the mags are not carried in a designated mag pouch, but instead carried in the pants pocket or jacket like during hot weather/light clothing wear or undercover deep carry, over about a three hour period, at least one if not all the rounds will be loose at the bottom of the pocket. I wrote to Kahr about 4 years ago and obviously they were not concerned enough to rectify the design. In all the years of off duty carry, I've never experienced that problem with any other make of semi auto. I have experienced this with just about mag model that Kahr makes. Curious as to whether anyone else has experienced this problem too. Aside from that, great weapons.
