Palmetto State Armory Debuts the 57 Rock Pistol

Palmetto State Armory showed off its new 5.7mm Rock pistol, a polymer-framed striker-fired handgun that uses Ruger 57-style 23-round mags – although the base Ruger mags aren't compatible due to the longer grip length of the PSA. The guns are in production now in two variants, a $499 base model and a $550 optics/suppressor-ready model. Delivery is set to begin in about three months.
