Standard Manufacturing S333 Thunderstruck Gen II .22 WMR Double-Barrel Revolver
The S333 Thunderstruck Gen II stands out for its patent-protected dual-barrel design that fires two .22 WMR cartridges with each trigger pull. Compact, light, and built on a hard-coat anodized 7075-T6 aluminum frame, this revolver offers eight-round capacity—delivering four volley shots before reloading. Its articulated two-finger trigger, triple-layered safety system, and fixed red 3-dot sights make it a uniquely engineered personal-defense option made in the USA.

The Thunderstruck’s double-action-only mechanism houses two 1.5-inch 4140 steel barrels stacked vertically. Each pull of the rugged 20-pound skeletonized trigger releases a pair of firing pins, sending two projectiles downrange simultaneously.
An eight-shot 4140 steel cylinder indexes four times, providing rapid follow-up volleys. The cylinder’s dark oxidized finish complements the matte black frame for a purposeful, uniform look.
Safety is layered: an articulated trigger-blade prevents accidental discharge, a transfer-bar system blocks hammer contact until the trigger is fully depressed, and a manual cross-bolt adds optional storage security.
Weighing about 18 oz unloaded, the compact frame pairs with finger-groove polymer grips for controlled handling during rapid double-projectile shots.
