About this product
The Ruger-57 is a semi-automatic handgun chambered in 5.7x28mm with a 4.94-inch barrel that delivers high-velocity performance with minimal recoil. Built with a through-hardened billet steel slide and glass-filled nylon frame, this pistol offers modern ergonomics and optics-ready capability. It ships with two 10-round steel magazines and weighs 24.5 ounces unloaded, making it a practical choice for range use and personal protection where the 5.7x28mm cartridge is appropriate.
What is the Ruger-57 used for?
The Ruger-57 is designed for range shooting, sport competition, and personal defense applications where its high-velocity, low-recoil 5.7x28mm cartridge is advantageous. The 4.94-inch barrel provides optimal velocity for the round while maintaining a compact 8.65-inch overall length. This makes it effective for both target practice and defensive scenarios requiring rapid follow-up shots.
How does the Ruger-57 compare to the FN Five-seveN?
The Ruger-57 offers comparable ballistics to the FN Five-seveN at approximately $300 less, making it the better value proposition for shooters wanting 5.7x28mm performance without premium pricing. However, the FN Five-seveN includes an ambidextrous safety and has a longer track record with military and law enforcement units. The Ruger-57's optics-ready slide gives it an edge for modern accessory mounting.
What does it weigh and what are the dimensions?
The Ruger-57 weighs 24.5 ounces empty and measures 8.65 inches in overall length with a 4.94-inch barrel height of 5.6 inches. The width across the frame is 1.3 inches, allowing for comfortable holster compatibility. These dimensions make it slightly lighter and more compact than many full-size service pistols while maintaining shootability.
Who is this NOT for?
This pistol is not ideal for shooters prioritizing maximum magazine capacity, as 10-round limits may restrict its utility for some defensive applications. Those accustomed to traditional calibers like 9mm may find 5.7x28mm ammunition more expensive and less available. For hunters needing more power, consider the Stevens 334 in .308 Win instead.
What's in the box?
The Ruger-57 ships with two 10-round steel magazines, a cable lock, and owner's manual. Unlike some competitors, it does not include optics mounting plates, which must be purchased separately. The package contains everything needed for immediate range use except ammunition and eye/ear protection.
Is the Ruger-57 worth it at $432.99?
At $432.99, the Ruger-57 provides excellent value for shooters specifically seeking 5.7x28mm performance without paying FN Five-seveN prices. The combination of quality construction, modern features, and Ruger's reputation justifies the cost for this niche cartridge platform. For those wanting a more traditional shotgun option, the Stevens 555 Sporting O/U offers reliable performance at a similar price point.

Frequently asked questions
- Is it compatible with FN Five-seveN magazines?
- No, the Ruger-57 uses proprietary magazines that are not interchangeable with FN Five-seveN magazines. The magazine well dimensions and locking mechanisms differ between manufacturers. You must use Ruger-57 specific magazines for proper function.
- Does it fit standard holsters?
- The Ruger-57 requires holsters specifically molded for its unique frame dimensions, which differ from common service pistol profiles. Most major holster manufacturers like Safariland and Blackhawk offer Ruger-57 specific models. The 1.3-inch width fits standard pancake and duty holster designs.
- How long does shipping take?
- Ironclad Armory processes firearm shipments within 3 business days after FFL verification. Ground shipping typically adds 5-7 business days depending on destination. All firearms require shipment to your local FFL dealer for transfer.
- Can I return it if there are mechanical issues?
- Ironclad Armory accepts returns within 30 days for manufacturer defects, which are handled through Ruger's lifetime warranty. Non-mechanical returns are subject to a 15% restocking fee. All returns must be initiated within the 30-day window and include original packaging.
- Does this work with Trijicon RMR optics?
- Yes, but requires a separately purchased mounting plate since the slide is drilled and tapped but not pre-milled for specific optics. Ruger offers RMR adapter plates for approximately $40. The mounting system uses a #6-48 screw pattern common to most micro red dots.
