The S333 Thunderstruck(TM) sets the standard for the ultimate in personal protection by simultaneously firing two rounds of .22 Win Mag with each pull of the trigger. With four pulls of the trigger, eight rounds are fired in only three seconds. By combining standard ammunition and birdshot, each pull of the trigger will deliver an incredible combination of firepower and very light recoil. The S333 Thunderstruck(TM) is incredibly reliable because it functions as a Double Action Revolver. These Revolvers are far more superior to any other automatic pistol which are rendered useless when they jam or misfire. Additionally, the two shots per pull, with four pulls of the trigger, makes the S333 Thunderstruck(TM) the most redundant and reliable personal protection firearm when your life is on the line. The S333 Thunderstruck(TM) also features an articulated safety integral into the trigger and requires a deliberate and full pull of the trigger before the transfer bar will clear from the firing pins and hammers. The resulting S333 Thunderstruck(TM) is the safest personal protection firearm available. Our patented design of the S333 Thunderstruck(TM) is the most compact and concealable firearm imaginable of its type. The small size allows it to be carried in your pocket or purse and can be easily retrieved when needed. The ergonomic design of the S333 Thunderstruck(TM) features a comfortable polymer grip, intuitive controls, and no clumsy safety. This makes the S333 Thunderstruck(TM) the ideal choice in personal protection when your life depends on it.
