ProMag 9mm Luger Drum Magazine for Glock 43X/48 50 Rounds - Black - SKU: DRM-A20 - UPC: 708279014550
Product Description
The ProMag DRM-A20 is a high-capacity 50-round 9mm drum magazine engineered specifically for the Glock 43X, Glock 43X MOS, and Glock 48 slimline handgun platforms. Designed to deliver maximum range capacity and extended trigger time without constant magazine changes, this 50-round drum multiplies standard factory payload fivefold for high-volume target shooting, PCC conversion platforms, and range training sessions.
Constructed from a proprietary impact-resistant, glass-filled black technopolymer, the drum housing features a steel-reinforced feed tower to ensure long-term structural integrity and dimensional stability under tension. The interior utilizes a heat-treated chrome silicon wire spring paired with an injection-molded polymer follower to maintain smooth, continuous cartridge elevation through fast firing cycles.
Featuring an ergonomic thumb-wheel ratcheting system integrated onto the front face of the drum, the DRM-A20 allows shooters to relieve spring tension manually while loading 9mm rounds, making high-capacity staging effortless and efficient.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Glock 43X, Glock 43X MOS, and Glock 48 slimline handguns (9mm Luger).
- Verify host pistol is completely clear, magazine removed, and chamber physically confirmed empty before servicing.
- Depress or rotate the front ratcheting loading wheel to relieve internal spring tension while inserting 9x19mm cartridges one by one into the feed tower.
- Ensure each round seats fully against the rear interior wall of the steel-lined tower.
- Insert the loaded drum tower firmly into the G43X/48 magwell until the magazine catch locks in place with a clear tactile click.
- To clean internal components, remove the perimeter housing screws, split the drum body, and clear out brass shavings or carbon buildup with a dry brush.
