There are guns… and then there are these guns. Some were made for extreme testing, others for pure novelty, and a few just leave you wondering what the designers were thinking. Whether it’s their size, shape, or straight-up weird purpose, these firearms all have one thing in common—you’re probably going to have to double-check that they’re real.
Let’s take a look at ten of the strangest firearms ever made.
1. The Punt Gun
This thing isn’t just big—it’s comically massive. The punt gun was used in the 19th century to hunt waterfowl by the dozens, firing over a pound of shot in a single blast. It wasn’t shoulder-fired either. You had to mount it on a boat.
It was so powerful that it could wipe out an entire flock with one pull of the trigger. Eventually, they were banned because they did too good of a job. They basically fished with a cannon.
2. The Magpul FMG-9
The FMG-9 looks like a chunky flashlight or maybe a weird power tool… until it folds out into a full-blown 9mm submachine gun. It was designed for security personnel needing something extremely low profile.
The folding mechanism is smooth, fast, and absolutely movie-worthy. Sadly, it never went into full production, but videos of it in action are still floating around, and they’re wild to watch.
3. The Apache Revolver
This little nightmare was designed for street gangs in the late 1800s. It combined a revolver, a folding knife, and brass knuckles—basically three bad ideas in one sketchy package.
The Apache had no trigger guard and no barrel, so it wasn’t exactly accurate. But at close range? You wouldn’t want to be anywhere near it. It’s more of a last-resort chaos tool than a practical firearm.
4. The Duck’s Foot Pistol
Imagine pointing your hand at someone and firing four barrels in a fan-shaped spread. That’s the idea behind the Duck’s Foot pistol. It was designed for crowd control—one shot to hit several attackers at once.
It was clunky, hard to aim, and probably terrifying for whoever was on the business end. Definitely not the kind of thing you’d carry every day, but as a room-clearer, it had its moment.
5. The Gyrojet Rocket Pistol
Instead of using traditional bullets, this pistol shot miniature rockets. Real, burning, accelerating projectiles. The Gyrojet was a 1960s experiment that looked cool on paper but didn’t really perform.
The problem? The rockets were slow at first and only gained speed after leaving the barrel. So close-range shots were weak, and accuracy wasn’t exactly tight. Still, it’s one of the most unusual ideas ever to reach production.
6. The XM42 Flamethrower
Technically not a gun in the classic sense, but it definitely shoots something—fire. The XM42 is a handheld flamethrower made for civilians. Yes, really. And no, it’s not legal everywhere.
It sprays a stream of fire up to 30 feet and looks like it came out of a video game. People use it for clearing brush or burning wasp nests, but let’s be honest—it’s mostly just a wild toy for grown-ups.
7. The TP-82 Cosmonaut Survival Gun
This triple-barreled space gun was issued to Soviet cosmonauts in case they crash-landed in the wilderness. It had two shotgun barrels and one rifle barrel, plus a detachable stock that doubled as a machete.
You won’t find this one in any regular armory. It was built with survival in mind—enough firepower to take down a bear or start a fire. Who knew space missions came with backup guns?
8. The Key Gun
At first glance, it looks like an old iron key from a castle door. But it’s actually a single-shot gun. These were sometimes used by jailers in the 1800s, combining a literal key to the cell with a very last-ditch weapon.
It wouldn’t win any awards for stopping power, but at close range, it was better than nothing. Just don’t fumble it while you’re unlocking something important.
9. The S333 Thunderstruck
This double-barreled revolver fires two .22 Magnum rounds at once with every pull of the trigger. Yes—every trigger pull sends out two bullets. It’s built for self-defense and looks like something straight out of a sci-fi flick.
It’s not exactly a precision instrument, but that’s not the point. It’s supposed to create a cloud of danger in front of you fast. Whether that’s effective or just excessive depends on who you ask.
10. The Zip .22
This one is infamous for all the wrong reasons. The Zip .22 was meant to be a cheap, modular .22 LR pistol, but the execution was… bad. Think constant jams, awkward controls, and weird design choices that made it a nightmare to shoot.
It looked futuristic, sure. But functionally, it just didn’t hold up. Still, it’s earned a weird cult following as one of the strangest flops in firearm history.
