Shield Arms Magazine Catch for Glock 43X 48 Gray Accessory

Shield Arms manufactures this steel mag catch, which is specifically engineered to work optimally with the Shield Arms S15 magazine. The catch remains compatible with plastic OEM magazines, though extended use with plastic mags can result in increased wear, and OEM mags may not drop free. Shield Arms does not recommend pairing their steel mag catch with plastic OEM mags. They recommend steel on steel or plastic on plastic configurations. If you have a first generation aluminum mag catch, it may not work with gen 2 S15 mags. Shield Arms recommends upgrading to one of their steel catch offerings.
