The Shield Arms Steel Magazine Catch for Glock 43X/48 in Gray (Shield Arms part no. G43X-EMR-GREY) is a steel replacement catch optimized to work with Shield Arms’s own S15 steel magazine. Shield Arms designed the catch to remain compatible with plastic factory magazines too, though the company notes it can cause increased wear on plastic mags with prolonged use and that OEM mags may not drop free from it. Shield Arms recommends steel-on-steel or plastic-on-plastic pairing for best results, and flags that a first-generation aluminum mag catch may not work with Gen 2 S15 magazines. This gray steel catch is built to solve that compatibility gap.
