ProMag DRMA109 30-Round 9mm Drum Magazine Shadow Systems CP920

The ProMag DRMA109 delivers extended firepower with its 30-round capacity specifically engineered for Shadow Systems CP920 pistols. This drum magazine transforms standard pistol platforms into high-capacity systems for competitive shooting and extended range sessions. Built from military-grade DuPont Zytel polymer, it maintains reliability while reducing overall weight compared to steel alternatives.

What Makes This Different

Unlike traditional stick magazines that extend below the grip, this drum configuration keeps the overall profile compact while tripling standard capacity. The DuPont Zytel polymer construction resists impact damage and environmental stress that can crack inferior materials. Internal spring mechanisms distribute tension evenly across all 30 rounds, preventing the feed issues common in high-capacity magazines. The proprietary geometry matches Shadow Systems CP920 specifications exactly, ensuring consistent lockup and reliable feeding.

Key Features

• 30-round capacity in compact drum configuration
• DuPont Zytel polymer construction for durability and weight reduction
• Engineered specifically for Shadow Systems CP920 pistol platform
• Internal spring system designed for consistent feeding pressure
• Textured exterior surfaces for secure handling during reloads
• Drop-free design releases cleanly from magwell
• Reinforced feed lips prevent deformation under stress

Range performance shows consistent feeding through rapid-fire strings and competition courses of fire. The drum design distributes weight closer to the pistol's center of gravity compared to extended stick magazines. Weather testing confirms reliable function in temperature extremes and moisture exposure typical of outdoor shooting environments. The polymer construction resists chemical cleaning solvents and maintains dimensional stability over thousands of loading cycles.
