In the realm of firearms, reliability and durability are non-negotiable. ProMag stands as a testament to these virtues with their exemplary 20-round magazine designed for the Ruger-57 chambered in 5.7x28mm. This is not merely an accessory but a crucial component crafted to meet the demands of both traditionalists and modern shooters alike.
At its core, this magazine combines robust construction techniques with advanced materials technology. The body is forged from heat-treated high carbon steel, ensuring resilience under rigorous conditions while being finished with black oxide for enhanced corrosion resistance. Complementing this traditional craftsmanship is a follower molded from military-spec polymer compounds through precision injection molding—a nod towards contemporary manufacturing excellence that ensures smooth operation and reliable feeding.
Spring tension is another critical factor where many fall short; however, ProMag rises above with springs formed from heat-treated chrome silicone wire, providing consistent pressure and longevity over countless cycles of use.
Each magazine emerges proudly Made in USA, embodying American ingenuity and commitment to quality by offering a lifetime guarantee against any manufacturer's defects—an assurance rarely matched in today's market.
