The Shield Arms Premium S15 Steel Mag Catch (brand part number G43X-PRM-BLK-RH) is a right-hand-specific magazine release built for the Glock 43X, optimized for use with the Shield Arms S15 steel magazine. Because this catch is built specifically for right-handed use rather than being ambidextrous, Shield Arms was able to eliminate hard angles on the bottom of the catch, giving noticeably smoother reloads with the steel S15 magazine. The catch face is extended by roughly .03 inch compared to Shield Arms’ standard mag catch, providing slightly more magazine engagement for a more positive lock-up. It is finished in black and built for shooters who want the sharpest reload performance a dedicated, non-ambidextrous catch can deliver.
