I have just returned from the range wherein I shot 20 rounds with my new R9s. I had to quit due to the trauma to my 2nd right distal interphalangeal joint. The joint bangs into the front inside trigger guard upon recoil. I have large hands and fingers with a span of 10 1/2 inches. Other than bandaging the joint, does anyone have any suggestions, e.g. changing the position of my grip on the pistol?
