Picked these up today in a lot I bought, no name make on them, the pair on the left for a square N frame, the right are J frame. The screws are Allen head screws, no typical S&w screws.
P.S check out the grain on these k frame round butt I picked on my model 19, they found a new home.
Got these 2 other S&W Maple grips, both are K frame square butt, the targets have black washers and football cutout, the mag as have silver washers, these are the first factory maple I’ve come across.
