The ProMag RUGA40 delivers reliable feeding and extended capacity for Ruger SR pistols chambered in 45 ACP. This 13-round magazine expands firepower beyond factory limitations while maintaining the dependable function shooters demand from their sidearm.
What Makes This Different
Constructed from heat-treated carbon steel with a corrosion-resistant blued finish, this magazine surpasses polymer alternatives in durability and longevity. The steel construction provides consistent spring tension over thousands of loading cycles, while the precision-formed feed lips ensure smooth cartridge presentation. Factory magazines typically hold fewer rounds, making this an immediate capacity upgrade for competitive shooting and tactical applications.
