Two-piece, extended base pad replaces factory pad to increase magazine capacity without compromising reliability. Molded from impact-resistant, fiberglass-reinforced nylon to protect your magazine from damage when ejected onto hard ground or pavement. Checkered bottom panel assists in fast, positive, non-slip, mag changes. Locks securely to the magazine body and lets you retain the factory magazine spring. Removes quickly and easily to reinstall factory pad and return mag to original spec. Models for Springfield XD are also available with optional extra power magazine spring for added reliability. Smith & Wesson M&P model is supplied with parts to allow two attachment options. For low-stress applications where the mag will not be ejected onto hard surfaces, use the spring plate to lock the extender and add six rounds. Use the L-shaped locking insert for extra-secure attachment and five additional rounds.
SPECS: Fiberglass-filled nylon, black. Springfield XD models available with extra power, steel music wire magazine spring.
