1875 / 1890 Remington Grips. These fit the Uberti made Remington "outlaw." These Grips are made of polyurethane to which the maker adds 20 to 60% Ivory or bone to get the finished color and antique look. The Grips are made to close specifications as to assure a good fit to your gun. Some sanding might be required to get a perfect fit.
When any of these grips are installed as a two piece grip they will require drilling a screw hole and installing Grips escutcheons and screw.
All Remington Grips are Two piece Grips.
