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. The 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 grey/black. Pachmayr G-10 Tactical grips are the toughest, most durable, and best looking semi-auto grips on the market.
