ProMag DRMA27 30-Round 9mm Drum Magazine Glock 17/19 Compatible

The ProMag DRMA27 delivers extended firepower with its 30-round capacity drum design engineered for Glock 17 and 19 pistols. This high-capacity magazine eliminates frequent reloading during extended range sessions and competitive shooting events. Built from reinforced DuPont Zytel polymer, it provides reliable feeding while maintaining durability under demanding conditions.

What Makes This Different

Unlike standard 15-17 round magazines, the DRMA27 nearly doubles ammunition capacity without requiring magazine changes during critical moments. The drum configuration distributes cartridge weight evenly, reducing the top-heavy feel common with extended stick magazines. DuPont Zytel construction offers superior impact resistance compared to standard polymer formulations, maintaining structural integrity through thousands of loading cycles.

Key Features

• 30-round capacity doubles standard magazine ammunition supply
• DuPont Zytel polymer construction resists cracking and deformation
• Direct compatibility with Glock 17, 19, and other 9mm Glock models
• Drum design prevents spring fatigue associated with compressed tower magazines
• Matte black finish matches factory Glock components
• Easy-load design reduces thumb fatigue during ammunition insertion
• Steel reinforced feed lips ensure consistent cartridge presentation

Range testing demonstrates reliable cycling with standard 115-grain through 147-grain 9mm ammunition. The drum mechanism feeds hollow points, ball ammunition, and match-grade cartridges without modification to the host firearm. Competition shooters benefit from reduced reload frequency during multi-target scenarios, while the robust construction withstands repeated dropping and impact stress typical of dynamic shooting sports.
