The Standard Manufacturing S333 Thunderstruck is a compact double-action revolver chambered in .22 WMR and designed around a unique dual-barrel firing system. With each pull of the trigger, the S333 fires two rounds simultaneously, allowing its eight-round cylinder to deliver four two-shot volleys. Its lightweight aluminum frame, compact dimensions, and polymer grip make it easy to carry, while the revolver-style operating system provides simple, straightforward function.

The S333 Thunderstruck also features an articulated trigger safety and transfer-bar system designed to prevent the firing pins from being struck unless the trigger is deliberately pulled through its full travel.

IMPORTANT: This firearm is not legal for sale in Massachusetts, Maryland, or California.

Ammunition Notice: S333 Thunderstruck revolvers are factory tested and regulated with CCI Maxi-Mag 40 Grain, CCI Maxi-Mag 40 Grain HP, and PMC Predator 40 Grain ammunition. Due to variations in .22 WMR ammunition, Standard Manufacturing recommends using appropriate high-quality loads for reliable operation.
