I am a small person. 5'2" 150lb. I hunt turkey with a 3&1/2 inch 12ga pump. The pistol stock helps me to hold on to the gun using #2 & 4 3&1/2 mag loads Also the LOP is adjustable. That makes my gun work for me. Not so good for the turkeys
It also helps avoid the wrist strain that would accompany using a traditional grip while sitting on the ground (typical in a turkey hunting situation) and allows for the grip-hand elbow to be jammed against the knee for extra stability.
