Hey Rob, this is a high serial number revolver same as yours. The previous owner had already replaced the original grips with the hogue monogrip but I did not have to remove the pin the hogue uses to secure the little "saddle" the grip screws into. Pretty much removed the hogue and these screwed into place.@Rabbit212
Those grips look good. Couple of questions, my SS, actually a Service Six is in the higher serial number group so I'd want grips to fit that frame. Is your SS in that SN group? Did you have to remove the roll pin from the grips? I had to do that on mine for some Hogues. Thanks in advance.
