Frequently Asked Questions
Is this magazine legal to purchase in California?
Yes. This ProMag Ruger 57 magazine is blocked to 10 rounds and is sold in compliance with California's magazine capacity laws. The physical body holds 20 rounds but is permanently restricted to 10-round capacity for sale in California-restricted states. Always verify current local regulations before purchasing any magazine.
Will this magazine fit and feed reliably in my Ruger-57 pistol?
This magazine is specifically engineered for the Ruger-57 chambered in 5.7x28mm. The heat-treated steel construction and chrome silicon wire spring are designed to maintain consistent feed-lip geometry and spring tension through thousands of load cycles, making it a dependable alternative to factory magazines.
How does the ProMag steel construction compare to the factory Ruger magazine?
The ProMag uses heat-treated high carbon steel with a black oxide finish, which is exceptionally resistant to wear and corrosion. While the OEM Ruger-57 magazine uses a polymer body, many shooters prefer the added rigidity and durability of steel-bodied magazines for long-term range use and storage. The precision injection-molded follower helps ensure smooth feeding regardless of body material.
