ProMag DRMA107 30-Round Drum Magazine 380 ACP Sig P365 Black

The ProMag DRMA107 transforms the Sig Sauer P365's capacity limitations with a 30-round drum magazine engineered for extended shooting sessions. This high-capacity drum magazine eliminates frequent reloading interruptions during training, competition, or recreational shooting. Built from impact-resistant DuPont Zytel polymer, the DRMA107 delivers reliable feeding performance in a lightweight package.

What Makes This Different

Unlike standard P365 magazines that limit shooters to 10-15 rounds, the DRMA107 drum magazine multiplies capacity by 200-300% without compromising reliability. The drum design distributes cartridge weight evenly around the magazine body, reducing stress on the magazine spring compared to extended stick magazines. ProMag's polymer construction weighs significantly less than steel drum alternatives while maintaining structural integrity under rapid-fire conditions.

Key Features

• 30-round capacity increases P365 firepower for extended shooting sessions
• DuPont Zytel polymer construction resists impact damage and chemical exposure
• Drum configuration reduces overall length compared to equivalent stick magazines
• Spring-loaded follower ensures consistent cartridge presentation to the chamber
• Textured grip surfaces provide secure handling during magazine changes
• Reinforced feed lips maintain proper cartridge alignment under stress
• Compatible with factory P365 magazine release mechanisms

Range testing demonstrates consistent feeding across various 380 ACP ammunition weights and profiles. The drum magazine functions reliably in both slow-fire precision shooting and rapid-fire drills. Competition shooters benefit from reduced reload frequency during stages requiring high round counts. The polymer construction resists temperature extremes and moisture exposure common in outdoor shooting environments.
