This review tests the Palmetto State Armory (PSA) Rock pistol in 5.7x28mm using a 5.56mm rated Griffin Armament Optimus Micro suppressor without a booster. The pistol, equipped with a Holosun 507K X2 optic, demonstrated reliable cycling and lock-back on an empty magazine, even with the suppressor's booster removed. This indicates good compatibility and robust performance for the PSA Rock in this configuration.
