I bought the P9 largely on the issue of weight and the full grip. It carries very easily. When I absolutely need a tiny gun in a pocket, I substitute my Seecamp for the Kahr. Although very lightweight, the P9 is soft enough recoiling and offers the full grip that allows for as much practice as you can afford. I shoot a fair amount of higher pressure rounds, mostly NATO ball, to save on ammo expense, and the gun has held up very well. I did install a heavier 22# recoil spring.
Which one would you buy and why
