The Premium S15® Mag Catch does NOT work with plastic OEM Glock® magazines. Due to enhanced engagement designed specifically for S15® steel magazines, this Premium catch is incompatible with OEM plastic magazines.
Upgrade Your Glock® 43X® or 48 with Premium Performance
The Shield Arms Premium S15® Steel Mag Catch represents the pinnacle of magazine catch design for Glock® 43X®/48 pistols. Unlike the ambidextrous Standard version, the Premium catch is hand-specific (left or right) with enhanced ergonomics engineered for competition shooters, law enforcement professionals, and enthusiasts who demand maximum performance.
Designed for smoother, faster reloads, this premium catch eliminates hard angles on the bottom edge and offers enhanced tactile feel with extended knurling (approximately 1/32" longer). The beveled design facilitates effortless magazine insertion while increased engagement with S15® magazines ensures positive retention even during dynamic shooting.
When paired with Shield Arms S15® 15-Round Magazines, you achieve 150% capacity over OEM (15 rounds vs 10 rounds) with competition-level ergonomics and reliability.
Why Upgrade to the Premium Steel Mag Catch?
Glock® plastic OEM magazine catches experience accelerated wear when used with steel magazines, particularly under the increased stress of higher capacity and heavier magazine weight. Their patented Shield Arms S15® 15-round magazines are precision-engineered steel magazines that perform optimally with steel magazine catches.
