I made an interesting discovery this morning. While looking on Ebay for a set of used (and cheap) Pachmayer grips for dads Victory I remembered a while back in a box of old gun stuff that was given to me was a NOS set of Pachmayer N frame grips. So I held them against the frame and they seemed to match perfectly and the screw hole in the same place. SO a quick swap out revealed they fit NEARLY perfectly except for a slight gap between the top rear of the grips at the backstrap. I pulled the screw and realized if a shim of soft material were placed at the front of the grip frame right behind the trigger guard this would pull the grip forward slightly and eliminate the gap at the rear. I cut a small piece of .o62 neoprene gasket material, placed it on the frame and installed the screw and now the grips fit perfectly. I don't know if this would work with a ROUND butt Smith but works perfectly on the square butt. Might help someone in the same predicament as I was!
