Clay, unfortunately not finding any drum mags compatible with the defender. They do make a 32 round stick magazine but no drum. Sorry but hope this helps, link to 32 round magazine here if interested...................... budsgunshop.com/product_info.php/products_id/714030226/promag+mpa+30+defense+9mm+32rd+black

Hi Clay and welcome. Unfortunately, not as configured. As configured, there are 32rd stick magazines - budsgunshop.com/product_info.php/products_id/714030226/promag+mpa+30+defense+9mm+32rd+black ------------------ changing the lower for a Glock Magazine compatible lower would allow Glock Mags and Drums to be used: https://masterpiecearms.com/shop/defender-dmg-grip-assembly-glock-mag-compatible/ ----------- Cheers, stay safe and enjoy!
