IMPORTANT NOTE: All S333s are shot tested and regulated with the following ammo: CCI Maxi Mag 40 Grain, Maxi Mag 40 Grain HP, and PMC Predator 40 Grain loads. We find there are large quality control issues with some ammo that cause issues with this gun.

The S333 Thunderstruck™ 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™ 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™ the most redundant and reliable personal protection firearm when your life is on the line.

The S333 Thunderstruck™ 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™ is the safest personal protection firearm available.

Our patented design of the S333 Thunderstruck™ 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™ features a comfortable polymer grip, intuitive controls, and no clumsy safety. This makes the S333 Thunderstruck™ the ideal choice in personal protection when your life depends on it.

    I bought this to provide quick and easy self defense for my family. The low recoil and ease of handling will allow my mother with fibromialgia the ability to protect herself despite her muscle pains.

    Strange looking gun! Very well made high quality. Smooth operation.
    Heavy pull on trigger, but has a definite wall and then breaks smooth.
    Think its a keeper!

    Oh on the 22 Magnum round . . . it creates a 3/8" hole (Times Two) with 18" of penetration.
    A 45 caliber creates a 3/4" hole with 14" of penetration.

    Definitely a unique buy. While it might not be the most accurate, it makes up for the punch! Two 22mag? That\'s like a 44mag! Well, maybe at point-blank range. At 7 yards, the two bullets hit the paper about 6 to 10 inches apart on average. I thought they would couple up like snake bites. But the bullet sway was just a lot more than expected. Out of the first 50 rounds, only failed to fire one cartridge. Coulda been the ammo though. It\'s small, but heafty. The trigger is rather big and hinders draw from a pocket or a purse. Over all, I think it\'s a good backup or definitely home/car defense. Something point blank you\'d use instead of a snub nose 38. You get 8 bullets, but only 4 trigger pulls, so use them wisely!

    It started by a friend sending me a photo of the S333 because he knows I love unique guns. Upon seeing it, I dropped what I was doing, started reading the specs, watching demo videos, etc. By the end of the day, I had placed an order for one!

    I love how comfortable the S333 feels in the hand, the overall size, functionality, and safety. Some people have told me that it looks unsafe, but once they check it out, they quickly realize it’s actually safer than most other guns. I’m very happy with the S333's accuracy & versatility. My S333 Thunderstruck is always the talk of the range and everyone wants to try it out!

    A good novelty, collector gun.

    A very unique and unusual pistol, but what a trigger pull !!!!!! Not good for much over 6 feet away, without allot of practice. Trigger pull is heavy, but about 3/4 of the way back, it lightens up, so I'm pulling to the right!! It's a good novelty, collector gun!

    I was with a friend at a gun shop in Des Moines who first pointed this pistol out to me. He thought it was cool and at first glance, I thought it was odd. I took a look at it but wasn’t much impressed at first. He was. Enough so that he bought it. When we arrived at his home, I took a better look. It was light but not too light. I looked for the safety and finally realized the ingenious design with the “two finger” pull. The more time I spent with the gun, the more I wanted to test her out.

    We went to the firing range and I took my Sig 9mm with me but to tell the truth, I spent more time with the Thunderstruck S333 than with my own pistol! My amigo kept asking for his pistol back! Again, to be honest, this is a great defensive weapon that’s easy to carry concealed and lethal with two 22 magnum rounds fired at once. We both shot off at least 300 rounds between the two of us and the gun performed remarkably well. She’s made for self-defense as long range accuracy was tough to achieve but even at 25 feet, the bullets met the target.

    While some might think this to be a great pistol for the Mrs., I personally want one for myself! The unusual design, the weight, the double-fire action, and the innovation from Standard, should make this a very popular pistol with the public. Bigger is not always better and in my opinion, this is a great little gun.

    Thanks for the opportunity and thanks for a remarkable product!
