The Taurus GX4 comes from the factory with two flush 11-round magazines. There is the standard magazine with a floor plate that is flush with the bottom of the grip and an optional 11-round magazine with a finger extension for those who prefer a larger grip surface.
Promag also has a 30 round drum for some backyard/range fun available.
But, as James G. Mentioned, it will depend on what state you live in which will dictate the size mags you can own/carry. But, There are different round count mags available for you to choose from if you're in a FREE state.
