The Standard MFG Thunderstruck S333 .22 WMR revolver is a unique take on personal protection that fires two rounds with each trigger pull—delivering eight shots total in just four trigger presses. Built on a double-action revolver platform, the S333 combines the inherent reliability of a revolver with an unconventional firing system designed to put multiple rounds downrange rapidly. Chambered in .22 Winchester Magnum, it offers light recoil while maintaining the mechanical simplicity and dependability that make revolvers popular for defensive carry.
The frame is machined from 7075 aircraft-grade aluminum with an anodized black finish—durable, corrosion-resistant, and lightweight at just 18 ounces. The compact 1.25-inch barrel keeps the overall profile small enough for pocket or purse carry, while the polymer grip provides a comfortable, intuitive hold. An integral articulated trigger safety and transfer bar mechanism require a full, deliberate trigger press before the firing pins and hammers are cleared—a deliberate safety feature that fires only when you want it to.
This is not a conventional revolver, and it's not for everyone. If you're exploring defensive options beyond standard single-action-per-trigger platforms and want something pocket-sized with minimal controls and straightforward double-action operation, the S333 presents an interesting alternative. The capacity of eight rounds combined with the two-rounds-per-trigger design means you have multiple opportunities to hit a threat. Double-action reliability means no manual safety levers to fumble under stress.
Note: The GEN2 version is not California-compliant, so check your local laws before purchasing.
