ProMag Standard 50rd Drum 9mm Luger Compatible w/Glock 43X/48 Black DuPont Zytel Polymer DRMA20

Glock upped the capacity of its small self-defense guns with the launch of its G43X and G48 pistols, giving users a stagger-stack magazine design loaded with more rounds. Now, Pro Mag is giving those same Glock owners a chance to have even greater magazine capacity, thanks to the company's drum magazine designed for the guns.

This Pro Mag Glock 48/43X Drum Magazine is made using a proprietary type of Zytel-based polymer originally made by DuPont. The housing is made from this material, while the upper feed tower features a carbon-steel lip reinforcement that's overmolded to aid in durability and lubricity. The drum is completed with an injection-molded magazine follower that tops a spring made from heat-treated stainless steel.

The Glock 48/43X Polymer Drum Magazine from Pro Mag is designed for use with 9mm cartridges only and features an all-black finish. The drum holds 50 rounds and is made in the USA.
