The 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.

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 may not work with Gen 2 S15 mags.

We recommend upgrading to one of our steel catch offerings.

Features:
Steel mag catch, several finish options
Ambidextrous
Compatible with Gen 1 and Gen 2 S15 magazines
Chamfered, textured button
Optimized for use with Shield Arms S15 magazines
Lower profile for concealed carry
