I just finished making these new grips for my Colt Huntsman. I had it engraved in 1986, and the factory grips just didn't match up to Joseph's beautiful work--so I used a piece of walnut that my Mom had saved for many years, and humbled myself with my clumsy skills at woodworking. They did turn out pretty nice, but I think I have 35 or 40 hours in them. They are retained on the handle by four neodymium magnets that I inlayed into the inside surfaces of the grips. I am pretty happy with the way they finally turned out.
