Standard Manufacturing S333 Gen III Volley Fire Pistol .22 WMR 8-Round 2.25″ Barrel Black

The Standard Manufacturing S333 Gen III is a purpose-built personal defense handgun chambered in .22 WMR, engineered with a unique volley-fire design that discharges two rounds simultaneously per trigger pull, delivering 8 total rounds from its double-column capacity. The Gen III represents a significant refinement over earlier models, featuring individually machined barrels threaded into a solid barrel thread nut that is precision-pressed into the frame and secured with reverse-angle screws for maximum rigidity and stability. A machined aluminum barrel shroud maintains barrel alignment and provides added protection, while the extended 2.25″ barrels promote more consistent powder burn and improved bullet stability over shorter-barreled predecessors.

The Gen III upgrade introduces a lightweight polymer lower frame for reduced carry weight without sacrificing durability. The redesigned 2-stage set-style trigger and hammer system delivers improved trigger control and a more deliberate, confidence-inspiring firing experience. Highly visible day/night glow sights are dovetailed into the frame front and rear, providing reliable target acquisition in a wide range of lighting conditions.

Whether you’re looking for a compact backup firearm, a unique addition to your collection, or a capable self-defense option in a proven rimfire magnum cartridge, the S333 Gen III offers a distinctive combination of innovation, craftsmanship, and practicality.
