ProMag DRMA31 30-Round Drum Magazine 9mm S&W M&P Shield

The ProMag DRMA31 transforms the S&W M&P Shield into a high-capacity platform with its 30-round drum configuration. This magazine significantly extends shooting sessions and reduces reload frequency during training or competition use. Built from DuPont Zytel polymer, it delivers reliable feeding while maintaining the Shield's compact profile.

What Makes This Different

Unlike standard 7 or 8-round Shield magazines, the DRMA31 provides nearly four times the capacity without requiring grip extensions or magazine wells. The drum design distributes weight more evenly than extended stick magazines, reducing printing during concealed carry. The DuPont Zytel construction resists impact damage and chemical exposure better than standard polymer blends, maintaining dimensional stability across temperature ranges.

Key Features

• 30-round capacity increases shooting time between reloads
• DuPont Zytel polymer construction for enhanced durability
• Engineered specifically for S&W M&P Shield pistols
• Drum configuration reduces overall length compared to extended magazines
• Spring-loaded follower ensures consistent feeding pressure
• Matte black finish matches factory Shield components
• Drop-free design enables rapid magazine changes

The DRMA31 performs reliably in competitive shooting environments where high round counts are standard. Training facilities benefit from reduced downtime during courses of fire, while recreational shooters appreciate extended range sessions without constant reloading. The polymer construction withstands repeated drops on concrete and functions in temperatures from -20°F to 180°F. Federal and state regulations may restrict capacity in certain jurisdictions.
