Going through a holster/grip plastic bin I have. I found these grips Possibly off a 586 I sold but am not sure. Is there a way to tell from the stamps on the back side. Thanks Ted
Those are for an N frame and made of Goncalo. No diamond around the screw but with black stock circle inserts so around 68-71.
I disagree. I think those are for a K/L-frame square butt. The indicator is the amount of wood at the 3 and 9 o'clock positions around the washer.
