About this product
What is the Ruger-57 5.7×28 4.94in Shimmer Gold Cerakote? It's a semi-automatic pistol chambered in 5.7×28mm with a corrosion-resistant Cerakote finish and optics-ready slide. Built on Ruger's polymer-frame platform, this handgun delivers the flat-shooting characteristics of the 5.7×28mm cartridge with improved ergonomics over earlier FN designs. The 4.94-inch barrel and 20-round magazine capacity make it suitable for both range use and defensive applications where ammunition compatibility matters.
What is the Ruger-57 used for?
This pistol is designed for range shooting, training, and personal defense where 5.7×28mm ammunition availability isn't a concern. The 5.7×28mm cartridge produces minimal recoil compared to 9mm, allowing for rapid follow-up shots and making it ideal for shooters who prioritize shot placement over sheer stopping power. With its 20-round magazine capacity and 4.94-inch barrel length, it balances compact carry potential with ballistic performance that exceeds most pistol calibers.
How does the Ruger-57 compare to the FN Five-seveN?
The Ruger-57 offers better value and modern features than the original FN Five-seveN at nearly half the price. While both fire the same 5.7×28mm cartridge, the Ruger features an optics-ready slide, improved ergonomics, and comes with two magazines versus FN's single magazine. The FN Five-seveN maintains better resale value and has longer track record, but the Ruger-57 delivers 90% of the performance at 55% of the cost.
What does it weigh and what are the dimensions?
Unloaded weight is 24.5 ounces with an overall length of 8.65 inches and height of 5.6 inches. The 4.94-inch cold hammer-forged barrel provides optimal velocity for the 5.7×28mm cartridge while maintaining a concealable profile. At 1.2 inches wide, it fits standard holsters designed for full-size pistols like the Stevens 334 Rifle counterparts in our inventory.
Who is this NOT for?
This pistol isn't for beginners or those on a tight ammunition budget. The 5.7×28mm round costs approximately $0.80-1.20 per round compared to $0.25-0.35 for 9mm, making practice sessions significantly more expensive. Additionally, the light recoil impulse requires different technique than traditional centerfire pistols, which might frustrate shooters accustomed to heavier platforms like the Stevens 555 Sporting O/U shotguns.
What's in the box?
You receive two 20-round steel magazines, cable lock, owner's manual, and the pistol itself with installed fiber optic front sight. The package does not include optics, holster, or additional accessories—plan for $150-300 in additional costs for mounting plates and micro red dots. The magazines feature anti-tilt followers and are compatible with aftermarket extensions increasing capacity to 30 rounds.
Is the Ruger-57 worth it at $478.99?
At $478.99, this represents exceptional value for entering the 5.7×28mm platform compared to the $1,200+ FN Five-seveN. You're getting a modern handgun with optics mounting capability, two magazines, and Cerakote protection that would cost $200-300 extra if applied aftermarket. The only caveat is ammunition cost—expect to spend $800-1,200 annually if shooting 1,000 rounds per year for practice.

Frequently asked questions
- Is it compatible with Holosun 507C optics?
- Yes, with a mounting plate. The slide is drilled and tapped for RMSc pattern, requiring a $40-60 adapter plate for Holosun 507C. Installation takes approximately 15 minutes with proper torque screwdriver set to 12-15 in-lbs.
- Does it fit Glock 17 holsters?
- No, requires specific holsters. The Ruger-57 has a 1.34-inch wide slide versus Glock 17's 1.0 inch, necessitating dedicated holsters from companies like Black Rhino Concealment or Tier 1 Concealed. Plan for $60-120 for a quality Kydex holster.
