Standard Manufacturing

The Standard Manufacturing S333 Thunderstruck is a unique double-barrel revolver chambered in .22 Winchester Magnum Rimfire that fires two rounds simultaneously with each trigger pull, effectively doubling the projectile mass delivered on target. It features an 8-round cylinder that indexes four times before reloading, firing two .22 WMR bullets at each stop. The aluminum frame and polymer grip keep weight manageable, and the double-barrel configuration creates a distinctive profile. The Thunderstruck was designed specifically for personal defense, where the twin-projectile concept aims to maximize the terminal effectiveness of the rimfire cartridge while maintaining the simplicity and reliability of a revolver action and minimal recoil for shooters sensitive to heavier calibers.
