G-10 material is a fiberglass based epoxy resin laminate. It is an extremely tough and durable material that is impervious to moisture, weather or chemicals, making it a perfect material for handgun grips. The multiple layered construction allows the use of different colors to be added to the semi-auto grips, creating attractive patterns as it is machined. Our Pachmayr G-10 Tactical pistol grips are available in two textures, our coarse Grappler pattern or fine Checkered, and two color patterns, green/black and gray/black. Pachmayr G-10 Tactical grips are the toughest, most durable, and best looking semi-auto grips on the market.
