Promag Ruger Sr40 40sw 25rd Bl Steel

The ProMag Ruger SR40 40 S&W 25-round black steel magazine delivers high-capacity firepower for Ruger SR40 platform shooters who demand reliability in training, duty, or competition environments. Built with precision-wound, heat-treated chrome silicon wire springs and domestic manufacturing standards, this 25-round magazine provides operators with extended engagement capability while maintaining the quality control that serious users require from mission-critical components.

Each magazine features all-steel construction designed to withstand the pressures of 40 S&W ammunition while maintaining feed reliability across thousands of cycles. The heat-treated chrome silicon wire spring resists weakening and corrosion, critical factors for magazines stored long-term or deployed in variable environments. ProMag's assembly process includes multiple quality checkpoints at every stage, ensuring consistent spring tension and follower geometry that translates to reliable feeding with factory and aftermarket ammunition. At 0.5 lbs and compact dimensions (3.75 x 1.5 x 14 inches), the magazine profiles efficiently in gear bags or tactical rigs without excessive weight penalty.

This ProMag magazine suits Ruger SR40 owners conducting duty training, high-round-count range sessions, or tactical courses where standard capacity limits engagement flexibility. The 25-round configuration extends trigger time between reloads—valuable for shooters refining shot placement or running movement drills. ProMag backs this product with a lifetime warranty against manufacturer defects, reflecting confidence in spring performance and welded construction integrity. Domestic manufacture and quality-controlled assembly make this a practical upgrade path for shooters seeking affordable extended-capacity options without compromising proven feed reliability.
