I am shooting full-size, soft recoiling 9 mm pistols. Smith & Wesson M &P, and HK VP9. Both are stippled. No problem assuming a good grip, but as the pistol recoils my third, fourth and fifth shooting hand fingernails start digging into the palm of my support hand. By the end of a string, my fingernails have left quite an impression in my flesh.
Obviously I have experimented with the various palm swells/back straps/grip panels available, but with no relief. It seems the harder I grip the gun, the more pain I cause myself. Can anyone suggest anything? Many thanks
