On a recent range session,I put a good number of rounds through my S&W J-Frame and qualified with it as my BUG. But, every time I shoot that little gun for great lengths of time, I eventually get some bite on my strong hand thumb (right hand shooter) getting smashed up into the cylinder release from recoil. Weak hand shooting, one or two hands is no issue. With my regular two hand grip, I try to keep my right thumb in tight and under my left hand, but invariably it will get chewed up a bit.
I may have to wear some tape on my thumb for range sessions in the future as a preventative measure. Any suggestions? Thanks
