The ProMag RUG04 Standard magazine delivers reliable feeding and extended capacity for Ruger P90 and P97 pistols in 45 ACP. This aftermarket magazine provides shooters with additional rounds beyond factory capacity while maintaining the dependable function expected from quality steel construction.

What Makes This Different

Unlike standard factory magazines, the RUG04 extends capacity to 10 rounds of 45 ACP ammunition through its lengthened steel body design. The blued steel construction offers superior durability compared to polymer alternatives, with heat-treated components that resist deformation under heavy use. ProMag's engineering focuses on consistent spring tension and follower geometry to ensure reliable chambering across various 45 ACP loads.
