Description
This is the OEM 10-round magazine built by Ruger specifically for the Ruger-57 chambered in 5.7x28mm. Black oxide steel construction paired with a polymer follower ensures reliable feeding and years of service without fail. The magazine holds 10 rounds in a double-stack configuration that's inherent to the 5.7×28 platform, packing solid capacity into a compact footprint.
Why the Ruger-57 10-Round Magazine Matters
For range days or carry situations, having factory mags on hand keeps your Ruger-57 running smoothly. This isn't an aftermarket or knock-off—it's built to the exact specifications and tolerances of the original magazines your pistol shipped with. That precision fit means no feeding hiccups, no wear on feed lips, and no compatibility guessing games. The numbered round-count windows on the side let you know exactly how many rounds you've loaded without thinking about it.
Built to Last
The steel body and black oxide finish handle daily use and range sessions without complaint. The polymer follower won't wear the magazine's internal edges, and the heat-treated spring maintains its strength through thousands of charge cycles. This is equipment meant to be grabbed, loaded, and trusted.
Practical in Every Scenario
Whether you're in a state with magazine restrictions or just want solid backup mags for your 5.7×28 setup, this factory 10-rounder does exactly what Ruger designed it to do. You'll get the same reliability and feed performance as the standard 20-round capacity, just in the 10-round format. The ambidextrous magazine release makes loading and clearing equally easy for either hand.

Frequently Asked Questions
Is this Ruger-57 magazine compatible with the 20-round standard magazine Ruger-57s come with?
Yes, this 10-round magazine works in any Ruger-57 pistol. The only difference is capacity. The magazine release, feed system, and internal geometry are identical to Ruger's factory 20-rounders, so they're completely interchangeable in your firearm.
Will new magazines be stiff to load?
Factory new magazines typically have tight springs and can require more effort to load at first. This is normal and actually a good sign—it means the spring has full tension. After a few loading cycles, the magazine will loosen up considerably and become easier to load while still maintaining reliable function.
Can I use the Ruger-57 magazine in other firearms?
No, this magazine is specifically designed for the Ruger-57 pistol and Ruger 5.7 LC Carbine. It won't fit or function in other handgun platforms. Always verify your firearm's specific magazine compatibility before ordering.
Does the Ruger-57 10-round magazine have round count indicators?
Yes, this factory magazine features numbered witness windows on the magazine body so you can see exactly how many rounds are loaded at a glance without unloading it.
