There are probably several things that can cause this, I recall a friend that had a Winchester model 24 that gave him a bloody 2nd finger every time he used it. The combination of its tight pistol grip stock and the abrupt crurve of the rear of the trigger guard were the culprits. converting it to an english grip ended the finger problem. Of course he still had to carry a screwdriver to get the empty shells out.
