Performance and Reliability

The double-stack magazine represents a practical evolution of 1911 magazine design. By stacking rounds in a more efficient pattern, this magazine delivers substantially more firepower without significantly increasing the grip circumference beyond what experienced shooters can manage. The matte steel construction provides durability and corrosion resistance suitable for regular use and storage.

As a factory Rock Island Armory product, this magazine is engineered to function reliably with your 1911 platform. Whether you're building a duty rig, sport shooting setup, or home defense battery, having multiple magazines ensures you're prepared for extended range sessions or tactical scenarios.

• 1911 shooters seeking increased magazine capacity
• Competition and sport shooting applications
