Wanted to mount a M1 horizontal front grip in my WH 1928 and had ordered one each of those Sportsman Guide horizontal and vertical grips. Today I started to put it on my gun and the cut out for the grip mount on both of the Sportsman Guide grips is 1/2 inch wide while my 1928 mount is 3/4 inch wide. Are the late model WH 1928's fitted with a special size mount or are the Sportsman Guide grips cut incorrectly? Thanks in advance for your help!!!
