Ruger 57 Pro 5.7x28mm Compact Pistol

The Ruger 57 Pro: A Modern Approach to Compact Carry

The Ruger 57 Pro represents a thoughtful evolution in compact pistol design, chambered in the efficient 5.7x28mm cartridge. This is a firearm built with the working shooter in mind—whether you're a professional, an enthusiast, or someone new to modern handguns.

Design and Ergonomics

Ruger has invested considerable effort in making the 57 Pro comfortable and intuitive to operate:

• Easy trigger reach and robust slide release for natural hand positioning
• Reversible magazine release accommodates both right and left-handed shooters
• Textured, ergonomic frame provides a secure grip without unnecessary bulk
• Picatinny-style accessory rail for mounting lights, lasers, or other tactical equipment

Reliability and Safety

The 57 Pro employs Ruger's proven Secure Action fire-control system, which combines a protected internal hammer with a bladed-safety trigger. This design delivers:

• Integrated trigger safety for secure handling
• Short, smooth trigger pull with a clean break and positive reset
• Neutrally balanced sear with significant engagement and strong spring tension
• Hammer catch to prevent unintended firing pin contact
• Light-weight firing pin for reliability and safety

Barrel and Slide

The through-hardened billet steel slide features lightening cuts that reduce weight while maintaining strength. The slide is drilled and tapped for optics mounting, making it easy to add a red dot sight for faster target acquisition. The alloy steel barrel receives a black nitride treatment for superior wear resistance and corrosion protection.

Sighting System

The 57 Pro ships with practical iron sights: a fiber optic front sight for rapid target acquisition and a windage and elevation adjustable rear sight. This combination works well for both traditional shooting and as a backup to mounted optics.

Capacity and Magazines

The double-stack steel magazine holds 20 rounds of 5.7x28mm ammunition without adding unnecessary bulk to the grip. Magazines drop free on release for quick reloading. The pistol ships with two steel magazines.

Practical Features

• Inspection port allows visual confirmation of chamber status without racking the slide
• Tool-free takedown makes field stripping straightforward
• Overall length of 8.65 inches and weight of 24.5 ounces** make this a genuinely compact carry option
