Hollow design and bottom door creates storage compartment within grip. Textured with Hogue's famous Cobblestone pattern for an efficient non-slip, non-irritating stippled grip. Made from long-lasting, durable, thermoplastic elastomer that ages gracefully for years of service. Virtually impervious to all oils and solvents associated with firearms. Amidextrous design ensures a comfortable grip for right and left-handed shooters. Meets ATF 922(r) requirements as a US-made pistol grip
