Shield Arms G43XEMRBLK Magazine Release Ambidextrous Black Aluminum for Shield Arms S15 Gen 1/2 Mags in Glock 43X/48

Shield Arm's steel mag catch is optimized to work with the Shield Arms S15 magazine. While it remains compatible with plastic OEM magazines, it can cause increased wear on plastic mags with prolonged use, and OEM mags may not drop free. Shield does not recommend using their steel mag catch with plastic OEM mags. They recommend steel on steel or plastic on plastic. If you have a first generation aluminum mag catch, it may not work with gen 2 S15 mags. Shield Arm's recommend upgrading to one of our steel catch offerings.
