(No reviews yet) Write a Review

Our steel mag catch is required to work with the Shield Arms S15 magazine. Using our steel mag catch with plastic OEM magazines can cause increased wear on plastic mags and OEM mags may not drop free. We do not recommend using our steel mag catch with plastic OEM mags. We recommend steel on steel or plastic on plastic. 

If you have a first generation aluminum mag catch, it is required to upgrade to one of our steel catch offerings.
