Product Description The Shield Arms Premium S15 Steel Magazine Catch is a left-hand-specific magazine release designed for Glock 43X/48 pistols and optimized for use with Shield Arms steel S15 magazines. Because it is not ambidextrous, the design eliminates hard angles on the underside to help promote smoother, more consistent reloads. This premium version features an extended catch face (approximately 0.03 in longer than the standard catch) for increased magazine engagement, plus extended knurling for improved control. Finished in a bronze coating and made in the USA, it is backed by a 100% lifetime warranty.
