Shield Arms Mag Catch/Release | Ambidextrous | G43X/48

This is an ambidextrous magazine catch intended for Glock 43X and 48 pistols and optimized to work with Shield Arms S15 magazines. The manufacturer copy notes compatibility with OEM plastic magazines but warns that using a steel catch with plastic OEM magazines can increase wear and may prevent drop-free operation. The listing references a low-profile design for concealed carry and a chamfered, textured button for tactile control.

Intended applications include everyday carry (EDC) where a lower-profile control is preferred, and competitive or practice shooting where positive magazine manipulation and ambidextrous operation are useful.
