The Shield Arms Premium S15 Steel Mag Catch is a right-hand magazine release engineered for Glock 43X and Glock 48 pistols. Constructed from S15 steel and refined for improved engagement, the premium catch increases contact with the magazine and smooths reloads by removing hard angles on the lower portion of the catch. The catch face is slightly extended—approximately 0.03 inches—versus the standard Shield Arms mag catch to provide more positive engagement during magazine seating and release.
