Overview
The Standard Manufacturing S333 Thunderstruck is an unconventional double-barrel 'volley fire' revolver chambered in .22 WMR. Built around a 7075 aircraft-grade aluminum frame with a high-strength steel eight-round cylinder, the S333 fires two rounds simultaneously - one from each of its vertically stacked barrels - with every double-action trigger pull, sending eight cartridges downrange in just four pulls. The pistol uses a distinctive two-finger trigger that requires both the index and middle fingers to operate, which the maker presents as a deliberate safety feature demanding intentional action to fire. Marketed as a compact, lightweight backup and personal-defense piece, the S333 leans on the combined effect of paired rimfire magnum rounds to compensate for the modest energy of a single .22 WMR.

Notes
Fires TWO rounds per trigger pull from vertically-stacked dual barrels (volley fire); 8-round cylinder = 4 trigger pulls. Two-finger trigger. Produced across Gen I, II and III (barrel length varies ~0.75 in to 1.5 in by generation; Gen III ~2.25 in). Integral articulated trigger safety plus transfer bar.
Background
The S333's signature trick is volley fire - pull the trigger once and two .22 WMR rounds leave the muzzles at the same instant, a mechanism more often associated with antique pepperbox and harmonica guns than with modern defensive handguns.
