Ruger SR40 Magazine 10-Round .40 S&W Blued Steel Factory OEM

The Ruger SR40 10-round magazine delivers reliable feeding and consistent performance for SR40 pistol owners. This factory original equipment magazine maintains the same quality standards and dimensional tolerances as the magazine included with new SR40 pistols.

What Makes This Different

Factory Ruger magazines feature precision-engineered feed lips and follower geometry specifically matched to SR40 chamber dimensions. Unlike aftermarket alternatives that may require fitting or cause feeding issues, this OEM magazine provides drop-in compatibility with zero modifications required. The blued steel construction offers superior durability compared to polymer alternatives while maintaining the exact spring tension specifications Ruger engineered for optimal cycling.

Key Features

• Factory OEM construction ensures perfect fit and reliable function
• 10-round capacity complies with restricted states and hunting regulations
• Blued carbon steel body resists corrosion and maintains dimensional stability
• Precision-formed feed lips prevent misfeeds and double-feeds
• Heat-treated spring maintains consistent tension through thousands of cycles

This magazine performs consistently across temperature extremes and extended storage periods.

Competition shooters rely on factory magazines for match-grade reliability, while law enforcement agencies specify OEM magazines for duty weapons to ensure consistent performance when reliability matters most.
