Shield Arms Steel Mag Release

For optimal performance when using Shield Arms S15 magazines in your Glock 43X/48, it’s advisable to upgrade to the Shield Arms Steel Magazine Catch. While a plastic magazine catch with a plastic magazine works fine, pairing a plastic catch with a steel magazine is suboptimal, leading to increased wear on the catch. Following the principle of plastic with plastic and steel with steel ensures longevity for both magazines and catches. Swapping out the magazine catch takes just a few minutes and significantly enhances the lifespan of your components.
