About This Firearm
The Ruger-57 is an internally hammer-fired 5.7x28mm pistol built for range shooting and home defense. It has an MSRP of $549, against $1,509 for the FN Five-seveN MK3 MRD.
Two steel 20-round magazines come in the box, and the frame carries a 1911-style ambidextrous thumb safety. Ruger's Secure Action fires a protected internal hammer through a bladed trigger, which does the drop-safety work. The through-hardened billet steel slide has lightening cuts and is drilled and tapped for optics, but the adapter plate is sold separately. The barrel is 4.94 inches of alloy steel with a 1:9 right-hand twist and no muzzle thread, the grip frame is glass-filled nylon, and at 8.65 inches overall and 5.6 inches tall nothing about it is small.
If you're cross-shopping, the FN Five-seveN MK3 MRD has an MSRP of $1,509, with a factory optic cut, an adjustable rear sight and a cold hammer-forged barrel for the same 20 rounds. The Smith & Wesson M&P 5.7 sits between them at an MSRP of $699 with 22 rounds, a threaded muzzle and 26.7 oz on the scale, so it covers the suppressor and optic jobs that this one leaves to the buyer.

Strengths & Limitations
- At 24.5 oz it undercuts the S&W by 2.2 oz while holding the same round count in a steel magazine.
- The ambidextrous thumb safety works the way a 1911's does, so there is no new lever position to learn.
- A billet steel slide with lightening cuts keeps reciprocating mass down without a polymer cover over it.
- Drilled and tapped is not optics-ready; the plate is a separate order before a dot goes on.
- No muzzle thread, so a suppressor needs an aftermarket barrel.
- A glass-filled nylon grip frame feels less substantial in the hand than the metal-cored frames on dearer 5.7 pistols.

Frequently Asked Questions
What is Secure Action?
Ruger's fire control. A protected internal hammer instead of a striker, released by a trigger with a bladed safety in its face that handles drop safety.
Has the name changed?
Ruger now markets the line as the Ruger-5.7. It is the same pistol, the same model number and the same suggested retail.
Which optic plate does it need?
Ruger's own adapter plate for this model, sold on its own. The slide is drilled and tapped for it instead of being cut to an optic footprint directly.
