Description
There is something addictive about shooting 5.7x28mm. The recoil is closer to a rimfire than a centerfire pistol, the bullet flies flat, and follow-up shots come fast. The Ruger-57 takes that cartridge and wraps it in a full-size pistol that still weighs only 24.5 ounces unloaded, thanks to a glass-filled nylon frame and a billet steel slide with lightening cuts. This version, model 16402, ships with two 10-round steel magazines and wears an all-black finish, with a black nitride treated alloy steel barrel that shrugs off wear over the long haul.
What Makes the Ruger-57 Shoot So Well
A lot of the credit goes to Ruger's Secure Action fire control, which pairs a protected internal hammer with a bladed trigger for a short, smooth pull, clean break, and positive reset. The controls will feel familiar if you have spent any time behind a 1911, with an ambidextrous thumb safety, a sturdy slide release, and a magazine release you can swap to either side. Sights are better than most factory setups too: a bright fiber optic front paired with a rear that adjusts for both windage and elevation. If you want a red dot, the slide is already drilled and tapped, so mounting one is as simple as adding the optic adapter plate.
Range Day and Beyond with the Ruger 5.7
The 4.94 inch barrel gets good velocity out of the 5.7x28mm round, and the 8.65 inch overall length balances nicely in the hand without feeling muzzle heavy. A Picatinny-style rail up front handles lights and lasers, and the inspection port lets you visually confirm chamber status at a glance. Whether you are after a fun range gun, a soft-recoiling option for smaller-framed or recoil-sensitive folks, or just want to see what the 5.7 hype is about, this pistol makes a strong case for itself. Ruger builds them in Prescott, Arizona, and the value here compared to other 5.7 platforms is hard to argue with.

Frequently Asked Questions
Can I mount a red dot on the Ruger-57?
Yes. The billet steel slide comes drilled and tapped from the factory, so you can mount a micro red dot using Ruger's optic adapter plates, which are sold separately. Until you add one, the fiber optic front sight and fully adjustable rear sight are solid performers on their own.
How much recoil does the Ruger-57 have?
Very little. The 5.7x28mm cartridge is known for being soft-shooting with minimal muzzle flip, and many people compare the feel to a .22 Magnum out of a pistol. That makes the Ruger-57 a favorite for high-volume range days and for anyone who is sensitive to recoil.
What magazines come with this Ruger-57 model 16402?
This specific configuration ships with two 10-round steel magazines. It is the same pistol as the standard 20-round version, just supplied with lower capacity mags. Ruger's factory 5.7 magazines are available separately if you want spares.
Is the Ruger-57 striker fired or hammer fired?
It uses Ruger's Secure Action fire control system, which pairs a protected internal hammer with a bladed safety trigger. The result is a short, smooth trigger pull with a clean break and a positive reset. You also get a 1911-style ambidextrous thumb safety for an extra layer of control.
