I have three sets of checkered square butt target grips for an N Frame. All three are very nice. Two have the "football shaped" indent and have the washers on the back of the medallions. The third set has the "football shape" completely cut out and there are no washers backing up the medallions.
I would take $60 for the ones without the washers, $85.00 for the walnut ones and $100.00 for the ones that are made out of Goncalo Alves wood.
