If you've picked up a Ruger 5.7, you know that reliable magazines are non-negotiable—especially when you're building out a defensive or range setup with a modern platform. This Ruger-57 5.7x28mm 20-round steel magazine 2-pack gives you the capacity and backup you need without the guesswork. Factory Ruger magazines are engineered to the same tolerances as your firearm, so you get consistent feeding and reliable performance every time you load up.

A two-pack is practical: one for your primary carry or duty load, and a spare ready to rotate in during extended range sessions or training. The 20-round capacity strikes a balance between capacity and practical handling, and the steel construction is built to survive hard use and repeated loading cycles. Whether you're running drills at the range, testing the 5.7x28mm platform, or keeping defensive-grade magazines on hand, factory Ruger magazines eliminate the guesswork that comes with aftermarket alternatives.

These are purpose-built for the Ruger 5.7—not a compromise, not a universal fit that might feel loose or wear prematurely. When your firearm's reliability depends on the magazine, betting on the factory magazine is the smart move.
