ProMag Glock 22/23/27 Drum Magazine – .40 S&W – 50 Rounds – DRM-A19
The ProMag DRM-A19 (UPC: 708279014529) is a high-capacity 50-round drum magazine designed for Glock-pattern pistols chambered in .40 S&W. In 2026, it remains one of the most popular "range-day" accessories for Glock enthusiasts, offering significantly more trigger time between reloads. Constructed from a proprietary DuPont Zytel™ based polymer, the drum housing is impact-resistant and engineered for high durability. To ensure consistent feeding and reliable lockup, the magazine tower features a full-length stamped steel internal insert, mirroring the structural integrity of factory Glock magazines.
This drum utilizes a precision-wound spring made from heat-treated stainless steel and an injection-molded follower to maintain smooth upward pressure. A convenient hand-crank loading mechanism on the front of the drum allows you to relieve spring tension while loading, making it much easier to reach the full 50-round capacity compared to traditional stick magazines. Proudly made in the USA and backed by ProMag’s lifetime guarantee, the DRM-A19 is the ultimate high-capacity solution for recreational shooting, competition practice, or any application where maximum round count is the priority.
Includes: (1) ProMag 50-Round .40 S&W Drum Magazine.
