Can't help you. In sixty years of shooting quality American doubles I've never had that problem. Everything from my Super-Fox shooting 3-inch magnums to a .410-bore NID. My Mother said her RANGER 12-gauge she got from Sears back in the 1930s kicked her finger. Long before the time I began shooting it (1959) my Great Uncle Art had restocked it for her with a straight grip and a quality trigger guard.
