Does anyone know of a source for aftermarket grips for the F/A 83. I know they are all individuals as they come from the factory, due to the way they finish each set of grips to each individual frame. I am just wondering if there is a place that will accept your grip frame for fitting, and what types of wood or other material will stand up to the recoil. I have an 83 in .475. I am not interested in Ivory, or white Micarta. I also know that the factroy will install the black Micarta for me, but I would like to hear from anyone who has hands on experience from an outside source.
