ProMag RUGA38 Ruger SR40 Magazine 25rd .40 S&W Blued Steel

The ProMag RUGA38 extends magazine capacity for Ruger SR40 pistols to 25 rounds of .40 S&W ammunition. This extended magazine provides significantly more firepower than standard factory magazines while maintaining reliable feeding and function. Built from blued steel construction, it delivers durability for extended range sessions and competitive shooting applications.

What Makes This Different

Unlike standard 15-round factory magazines, the RUGA38 nearly doubles ammunition capacity without compromising reliability. The steel body construction provides superior strength compared to polymer alternatives, while the blued finish offers corrosion resistance. Internal spring tension maintains consistent feeding pressure across all 25 rounds, ensuring reliable chambering from first shot to last.

Range testing demonstrates consistent feeding across various .40 S&W ammunition weights and manufacturers. The extended capacity proves valuable for competitive shooting disciplines requiring high round counts, tactical training scenarios, and extended range sessions. Steel construction withstands repeated loading cycles and environmental exposure better than polymer alternatives. The magazine functions reliably in temperatures from -20°F to 140°F according to ProMag specifications.
