Some people have problems with the Surefire pump action shotgun forend smashing their support hand index finger. I have experienced this myself. I suspect persons with longer arms encounter this more than users with shorter arms. I'm not impressed with the suggested solution of "grip the forend further back". I had an idea about a possible solution. Use a piece of 4x4" 0.5" thk Durometer 50 OO Sorbothane w/self-adhesive backing. McMaster-Carr #8794K112 $9.82 ea http://www.mcmaster.com/ (60 to 90 OO is used for shooting shoulder pads.) 50 is more easily deformed than 90 OO. Cut out to fit the triangular rear-facing surface Of the forend, and stick on using the integral adhesive. Will provide a recoil cushion for the off-hand index finger When cradling and operating the forend from the underside. Thoughts?
