Grips for the Colt SAA will fit the Gaucho. I found some dealers making grips and selling them on Ebay. If you don't mind doing some minor fitting, can get some nice grips at a very reasonable price there. Got some plastic ivory ones with the old Colt design for less than $ 25.00. Had to fit them by sanding and drilling a hole for the pin. Took less than an hour, getting my tools out and taking my time to do the work slowly.
