Possibly. If the rosewood insert is the same size as that used for the SP101, then yes. If you are not sure, feel free to email me a pic and I can tell you if such is the case.
I have a set of Pachmayrs for sale here on the Classifieds that are for the compact frame GP-100. They fit my 3" stainless GP-100 perfectly, I just prefer the original grips.
