I found a model 15-2 2 inch barrel .38 special, serial dates to 1965. It came with non-original grips, however I have a lead on the original set that came with the revolver and hope to put them back together. Interesting that the revolver has a serrated trigger. I have a set of K frame square butt magna that I was going to temporarily place on the revolver, however they seem to be too long from the grip frame pin to the medallion notch in the frame. I seem to recall the model 15 2" do have a slight difference in the frame than the 4". Is this the case and if I cannot acquire the original grips I would like to find a Smith and Wesson set of grips that would correct to the gun; square butt magna with diamond around screw. Would I need to find a set from a 2" model 15 or would a model 10 or similar work? Thanks
