Shield Arms Magazine Catch/Release, Fits Glock 43X/48, Steel, Blue

The Shield Arms steel magazine catch is designed for optimal performance with Shield Arms S15 steel magazines. While compatible with standard plastic magazines, using it with plastic mags will accelerate wear and may prevent them from dropping freely. Shield Arms strongly advises against using their steel catch with plastic magazines, recommending steel-on-steel or plastic-on-plastic configurations. Additionally, first-generation aluminum Shield Arms magazine catches are incompatible with second-generation S15 magazines, necessitating an upgrade to a steel version.
