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.

    A unique firearm

    Posted by Jeb Smith on 24th Oct 2021

    This is a unique firearm in all respects. The only thing that makes it a “revolver” is the fact the eight rounds of ammunition are held in a revolving cylinder. All other aspects of the pistol; barrels, grips, trigger, trigger guard, and safety are like no other currently on the market.

    I have used the S333-Gen II for over two months, putting 300 rounds through it. I find this a very good self defense pistol. It is not a target pistol, it is not casual plinker, it is a brawlers gun. Fast shooting, hard hitting and easy (with practice) to keep on target.

    I find the unique trigger system perfect for my arthritic hand giving my two fingers the strength I do not find with only one finger on many other guns. Do not compare this pistol to any others, it has its own manual of arms even in using a rolling down pull to clear the OEM shoulder holster. Keep the pistol in an upward direction and strike the ejector rod sharply and you will get a clear cylinder.

    Practice with this firearm, as with any firearm, and you will hopefully find it a competent defensive companion.

    I've had my S333 out back on the target range now at least 3 times. If I could find crimped snake shot I'd get some. But I use Federal 30 and 50 alternate in it. (MY CCI (Meat Eater) just arrived today) The slight speed difference makes a nice impact. Handles the Federal ammo fine.

    Fun Shooter!

    Posted by John on 17th Sep 2021

    It's a neat gun.trigger takes some getting used to. not a good EDC due to trigger guard and where will you find a holster? I still look at it as a 4 shot revolver.But It is cool to look at and does function very well.very very reliable too! fun to shoot for sure. Pros: shoots 2 rounds at the same time.good grip Cons: too much trigger.its a novelty gun.

    Will the S333 also fire 22LR?

    A good option for self defense

    Posted by Paul Hathcox on 24th May 2021

    I bought one of the original S333 revolvers (before they extended the barrel just a little) and I think it's a good option for self defense. 22 magnum is a formidable round without significant recoil. Two at the same time means a bad day for an attacker. Recoil goes up a little firing two rounds at once but it still felt like less than your average 38.

    Ignore the YouTube reviews that bash this revolver. They are usually trying to use it in ways it was never intended.
    This is not a competition revolver. You won't hit targets accurately from 20 yards. This is an up close and personal "get off me" gun. If you train with this revolver you will hit an attacker at standard self defense ranges. Think about it though. If you're further out than that and you're shooting at someone you will probably face legal scrutiny.

    The trigger might look strange at first. It's because you need two fingers to fire the gun. That turns out to be a good safety measure. After a little practice (I really mean just a little practice...I got the hang of it on my first day of shooting) the trigger is very easy to get used to.

    I have big hands but this gun felt good in my hand. My wife has much smaller hands but she said it felt good in her hand too. She liked the Thunderstruck revolver so much that she "borrowed" it from me and now it' serves as her EDC

    Unique, Useful and Interesting

    Posted by Douglas M. on 8th Apr 2021

    So many reviews don't get what this little gun is all about. It's never going to be a range toy, and it's not a bulky 45acp. It's a close quarters, easy to carry and easy to use, last ditch, self defense gun. It's also completely unique and worthwhile for that alone. And with the right ammo (and there''s some devastating stuff out there) it's completely viable for a CCW. But, you'll still get a funny look when you pick it up from your FFL holder, at least I did.

    Literally The BEST 22 Mag for the money

    Posted by Andy Bryan on 9th Mar 2021

    I first saw the S333 about 8 months ago when a friend showef me his new personal protection piece. I was intrigued because he is a firearms dealer and can carry anything and has chosen the Thunderstruck for his own use. I waited and followed the reviews. Then I decided that I wanted one. It took me 6 months to find one in stock locally. I LOVE IT. at 30 feet it is still accurate. I have not tried a longer distance because that' is as far as a situation would probably occur. After about 50 rounds and a slight oiling this gun is impressive. It fits In my pants pocket and it always ready in the event of an emergency. I have carried a concealed handgun for over 30 years and this is the first time I truly appreciate the quality of my protection. With twin discharges even if there was a misfire you still have a high probability of survival in a conflict. Don't let anyone fool you and tell you these guns are not lethal. It truly has extreme stopping power. Great feel just the right weight proportion and with 8 rounds you can have peace of mind in knowing that any target will be neutralized. Also, these are LOUD. That in itself is enough to end a conflict. When life matters do not trust your safety to a cheap imported or substandard firearm. They are a bit more expensive because they simply work.

    S333 Much Better than YouTube Reviews Describe

    Posted by Philip S. on 17th Feb 2021

    Many of the poor reviews posted about this gun are not fair for many reasons. The S333 THUNDERSTRUCK is not advertised as a sharpshooter weapon. The S333 THUNDERSTRUCK is made for very close range self defense—3 yards or closer. Many complaints refer to keyholing resulting from tumbling projectiles. I think most keyholing is caused by one bullet firing a very short faction of a second sooner than the other and the resulting recoil causes the other bullet to leave the barrel in a tumble. I believe this can be minimized by using ONLY the recommended ammunition and by firing the gun as steady as possible using two hands.

    However, in most sudden self defense scenarios, you don’t have time to aim with precision and steady the weapon. That’s what makes this gun quite useful in sudden self defense situations. This gun has built in redundancy with each pull of the trigger. If one barrel misfires, you have the other barrel blasting a bullet in the direction you point it. When both barrels fire—even if one bullet tumbles—the target receives the punch of two projectiles striking at around 1000 feet p.s.. Just think of the tumbling bullet as a bonus round. It will still do some damage at 1000 f.p.s..

    Additionally, you can fire 8 rounds of magnum ammunition with 4 pulls of the trigger within 3 seconds! At close range of 9 feet or closer, your assailant will more often than not, be neutralized.

    The S333 THUNDERSTUCK’s highly concealable form along with its safety features makes for a utilitarian close range self defense weapon.
