The unique easy-access floor plate design allows maintenance without removing the extension, while index cuts provide positive grip when drawing from magazine pouches.
Each pre-installed magazine includes an upgraded +10% power spring for reliable feeding with the extended capacity. The extension is USPSA 141.25 gauge compliant for competition use and fits most aftermarket flared magwells including Shield Arms Carry and Premium Magwells.
