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.

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 grey/black..
