Magpul PMAG D-50 GL9 9mm 50rd Black Polymer Drum Magazine MAG1033-BLK

The Magpul PMAG D-50 GL9 9mm Drum Magazine is a lightweight, ultra-reliable 50-round high-capacity feeding system engineered specifically for double-stack 9mm Glock handguns and compatible pistol caliber carbines. Utilizing the robust, impact-resistant polymer construction that defines the PMAG series, this drum magazine delivers maximum durability and structural integrity while keeping the overall footprint exceptionally compact. The innovative internal geometry handles single-column feeding transitions smoothly, using a unique rear-facing ratcheting lever that takes all spring tension off the follower to make manual loading quick and effortless. To simplify tracking, the rear of the drum includes a transparent window layout alongside a high-visibility follower, letting the shooter monitor ammunition counts at a glance during high-volume tactical or competitive shooting stages. Complete with a snap-on impact dust cover to seal out debris during storage, this rugged drum provides a reliable, heavy-duty solution that ensures consistent feeding performance without the awkward vertical length of extended stick magazines.
