Shield Arms Ambidextrous Magazine Release for Glock 43X/48, Black Aluminum

The Shield Arms Ambidextrous Magazine Release (brand part number G43X-EMR-BLK) is a steel mag catch machined from black aluminum and optimized specifically to work with Shield Arms’ own S15 magazine in the Glock 43X and Glock 48. While it remains compatible with plastic factory magazines, Shield Arms notes that a steel catch can cause increased wear on plastic OEM mags with prolonged use, and factory mags may not drop free as cleanly; the company recommends running steel-on-steel with S15 mags or plastic-on-plastic with factory mags. Owners with a first-generation aluminum mag catch should note it may not work correctly with Gen 2 S15 magazines and should upgrade to a current steel catch offering.
