Shield Arms Premium S15 Steel Magazine Catch, Left-Hand, Bronze, Glock 43X/48

The Shield Arms Premium S15 Steel Magazine Catch (Shield Arms part no. G43X-PRM-BNZ-LH) is a left-hand-specific replacement magazine catch finished in bronze PVD, built for the Glock 43X and 48 running Shield Arms’ S15 steel magazine. Because it’s optimized specifically for left-hand use rather than built ambidextrous, Shield Arms was able to eliminate the hard angles a universal catch needs, giving smoother magazine insertion and release. The catch face extends about 0.03 inch farther than Shield Arms’ standard mag catch, adding slightly more magazine engagement, and the extended 1/32-inch knurling gives a more positive, ergonomic press. Made in the USA and backed by a lifetime warranty, it’s built specifically to run with the S15 steel magazine rather than the factory plastic OEM magazine.
