ProMag DRMA110 50-Round Drum Magazine 9mm Shadow Systems CP920

The ProMag DRMA110 delivers extended firepower with its 50-round capacity specifically engineered for Shadow Systems CP920 pistols. This high-capacity drum magazine transforms standard pistol platforms into sustained-fire capable systems for competitive shooting and training applications.

What Makes This Different

Unlike standard stick magazines that require frequent reloading, this drum configuration provides 2.5 times the capacity of typical 20-round magazines. The DuPont Zytel polymer construction offers superior chemical resistance and dimensional stability compared to standard polymer blends. The drum's low-profile design maintains weapon balance while maximizing ammunition capacity.

Key Features

• 50-round capacity reduces reload frequency during extended shooting sessions
• DuPont Zytel polymer construction resists impact, chemicals, and temperature extremes
• Shadow Systems CP920 specific fitment ensures reliable feeding and ejection
• Drum configuration distributes weight evenly for improved weapon balance
• Spring-loaded follower system maintains consistent feeding pressure
• Reinforced feed lips prevent deformation under stress
• Easy-load design reduces thumb fatigue during ammunition loading

Competitive shooters benefit from extended strings of fire without reload interruptions, while training applications allow for sustained practice sessions. The robust polymer construction withstands repeated loading cycles and maintains dimensional accuracy across temperature ranges from -20°F to 180°F. Field testing demonstrates reliable cycling through 1,000+ round counts without spring degradation.
