Rock Island Armory DY910 9mm Magazine 10-Round Capacity

The Rock Island Armory DY910 magazine delivers reliable 9mm ammunition feeding with a restricted 10-round capacity for compliance in ban states. This factory magazine maintains the same build quality and materials as standard capacity versions while meeting legal requirements for restricted jurisdictions.

What Makes This Different

Unlike aftermarket alternatives, the DY910 uses Rock Island's original equipment manufacturer specifications and materials. The magazine body features heat-treated steel construction with a corrosion-resistant finish that matches the durability standards of full-capacity magazines. Internal components include a precision-wound spring and anti-tilt follower designed specifically for the reduced capacity without compromising feed reliability.

Key Features

• Factory Rock Island Armory construction ensures perfect fit and function
• Heat-treated steel body with corrosion-resistant black oxide finish
• 10-round capacity complies with restricted state regulations
• Anti-tilt follower prevents jams and double-feeds
• Precision-wound spring maintains consistent feeding pressure
• Compatible with Rock Island 1911 9mm pistols
• Removable floorplate allows for cleaning and maintenance

The DY910 performs consistently across various 9mm loads, from 115-grain ball ammunition to 147-grain hollow points. Law enforcement officers in restricted states rely on these magazines for duty use, while competitive shooters appreciate the consistent feeding during precision shooting events. The reduced spring compression at maximum capacity helps maintain reliable function even when stored loaded for extended periods.
