I just purchased a Ruger SS GP 100 357. It is a great looking gun, but it has the ugliest handgrips I have ever seen. I guess they serve the purpose, but I bought an older rubber grip with the wooden side panels, which look and feel much better. But, I cracked one of the panels when I tightened up the grip screw. Does anyone know if the SP model Rugers panels will interchange with the GP? Did Lett grips make a full wooden grip for the earlier model GP? I can easily find all sorts of Ruger wooden grips for every other Ruger made except a GP. I guess these are more rare than the service model Rugers.
