About This Firearm

The PSA Rock 5.7 is a striker-fired 5.7x28mm pistol built for range shooting and plinking. Palmetto State Armory still builds it, and its steel magazine holds 23 rounds, three more than the Ruger-57's 20.

Two of those magazines come in the box, the magazine catch reverses for a left-handed shooter, and the frame carries a Picatinny rail for a light. The slide is 416 stainless under QPQ and the barrel is fluted carbon steel with the same treatment, 4.7 inches with a 1:9 twist, and the gun weighs 25 oz. This configuration has no optic cut, so a dot means slide milling or one of the optics-ready Rock models Palmetto State Armory sells separately. Safety is passive throughout, a trigger lever and a striker block with no manual lever to set.

If you're cross-shopping, the Tisas PX-5.7 FO has an MSRP of $501.99 and is the other budget delayed blowback gun in the caliber, at 25.75 oz and 8.6 inches with a fiber optic front sight, and it has no optic cut either. The Ruger-57 has an MSRP of $549, holds 20 rounds at 24.5 oz, and its slide is at least drilled and tapped, so a dot there costs a plate instead of machine work.

Best For

GOOD
Range/Target
Twenty-three rounds between reloads, and a QPQ-treated stainless slide holds up to high round counts.
GOOD
Plinking
The fluted barrel takes weight off the front of the gun, and a trigger with nothing to disengage makes it simple to hand to someone new.
FAIR
Home Defense
Capacity and a light rail are there, but with no optic cut and no manual safety this is a thinner setup than the optics-ready guns in the caliber.

Strengths & Limitations

Strengths
  • Two 23-round steel magazines in the box.
  • A 416 stainless slide finished in QPQ is a harder surface than a plain blued or nitrided one.
  • The magazine catch swaps sides with no extra parts, and the full-size polymer grip is a familiar shape to anyone off a service pistol.
Limitations
  • No optic cut on this configuration, where the Ruger-57's slide is at least drilled and tapped.
  • The barrel is carbon steel under its QPQ, so it wants more attention in humid storage than a stainless-barrelled rival.

Frequently Asked Questions

Can a red dot be added?

Not without machine work on this slide. The other route is one of the optics-ready Rock 5.7 models Palmetto State Armory lists separately.

What safeties does it have?

A trigger safety and a striker block, both passive. Carry and storage decisions rest on the holster instead of a lever.

Are the magazines steel or polymer?

Steel, which survives being dropped on concrete better than a polymer magazine.
