I am buying a new model 686 and don't really care too much for RB grips.I really like the older style SB grips.Has S&W ever offered a RB to SB conversion grip in the Coke style.Also I was wondering if there's any way to make a set of SB grips work on RB frame.I know companies like Hogue make a set of conversion grips but really want a set of factory SB style grips.Any suggestions would be appreciated.
