The KRISS MagEx2 extension kit dramatically boosts the capacity of Glock-pattern .45 ACP magazines for use in KRISS Vector platforms and other firearms feeding from extended G21 magazines. The kit includes an extended spring and reinforced polymer extension body that assemble onto a factory magazine, turning it into a high-capacity powerhouse for range sessions and competition. KRISS engineers these kits specifically for reliable feeding at Vector cyclic rates, so function stays consistent even under fast fire. A straightforward upgrade for Vector owners who hate reloading.
