Standard Manufacturing S333 Thunderstruck Revolver, .22 WMR, 2.25-Inch Barrel, Black

The Standard Manufacturing S333 Thunderstruck in .22 WMR (brand part no. S333 GEN III) is a genuinely unique concealed-carry revolver: each deliberate trigger pull fires two .22 Magnum rounds simultaneously through side-by-side barrels, delivering far more impact per pull than a conventional single-barrel revolver. Standard Manufacturing builds the S333 with an in-trigger safety block and a firing-pin transfer plate, so the gun cannot discharge unless the two-finger trigger is pulled through its full travel, guarding against accidental drops or a struggle for the gun. Gen III updates bring a lighter polymer lower, a two-stage set-style trigger, and dovetailed day/night glow sights front and rear for improved accuracy and control. The compact, lightweight frame and light trigger pull are built for shooters who want maximum control with smaller hands. Among unconventional carry options in the revolvers category, the S333 favors shooters who want a devastating close-range option in a compact package.
