Description
These are the factory magazines you want if you own a Ruger-57. Built from quality alloy steel with a black oxide finish, they deliver the same reliability and precision fit you get from Ruger's standard equipment. Each magazine holds 10 rounds of 5.7x28mm and comes with polymer followers and base plates designed for smooth, trouble-free feeding.
What Makes the Ruger-57 Magazine Stand Out
You're getting genuine OEM parts here, which matters more than you might think. These magazines are manufactured to the exact same specifications and tolerances as the ones shipped with new Ruger-57 pistols, using identical materials and processes. That means perfect fit, consistent performance, and no compatibility headaches. The polymer internals combined with the steel body give you a magazine that's durable enough for regular use without unnecessary weight.
Built for Real-World Use
The 10-round capacity makes these especially useful if you're in a jurisdiction with restrictions, or if you just want lower-capacity options for certain shooting situations. The magazines load more like an AR than a typical pistol magazine, which users consistently report makes topping them off faster and easier than expected. The witness holes on the side let you see your round count at a glance without having to think about it. Multiple reviews from actual users confirm these magazines work flawlessly right out of the box with no break-in needed.
The Value Pack Advantage
Two magazines give you realistic flexibility for range sessions or training. You can rotate them while cleaning, have one loaded while you work with the other, or simply have reliable backups on hand. Since these are genuine factory parts with the same construction standard as original equipment, you're not compromising on anything to get the value of buying two at once.

Frequently Asked Questions
Are these Ruger-57 magazines compatible with the LC Carbine?
These 10-round magazines are designed specifically for the Ruger-57 pistol. While there are compatible versions for the LC Carbine, you should verify compatibility with your specific platform before purchasing. The Ruger-57 magazine is the primary intended use for this product.
Do these magazines require a break-in period?
No. These are factory-fresh magazines that work straight out of the box with no break-in needed. Multiple owners report zero malfunctions or feed issues right from the start. They perform flawlessly in testing with various ammunition types.
Why are these 10-round instead of 20-round?
The 10-round capacity is ideal for shooters in jurisdictions with magazine restrictions, or for those who prefer lower-capacity magazines for specific training and range scenarios. If you want standard 20-round capacity, Ruger also makes those as a separate product. Both are genuine Ruger factory magazines built to the same quality standards.
How do the Ruger-57 magazines load compared to other pistol magazines?
These magazines load more like AR-platform magazines than traditional double-stack pistol magazines. Because of the unique shape needed for the small 5.7x28mm round, users find they can load and top-off rounds faster and more intuitively than with most other handgun magazines. No speedloader required for most users.
