These Ruger Compatible SP101 Grip Inserts are constructed of solid wood and then stained and dyed for a “Ebony” finish. Each insert is engraved with 3D texture and very fine detail and I can also offer custom engraving with names, logos, initials, or anything you desire. Inserts fit in the black rubber grip but the rubber grip is not included. The provided picture is an example of the set you will receive, although the grain patterns and colors may vary as each piece of wood is unique. Payment is required within 3 days of purchase.
