I have a S&W 29-5 Classic .44 magnum with pachymar rubber grips. (5"barrel, fully underlugged). I'd like to change the grips to maybe a Hogue conversion set. The gun has a round butt with some kind of "bracket" attached to the bottom with a hole in it for the screw to fit into. Do wood grips fit into this bracket or does it have to be taken off (somehow)? Thanks.
