Quick Answer
Weird and bizarre guns are firearms that used unusual actions, strange ammunition, odd shapes, or highly specific designs that never became mainstream. Some, like the Krummlauf and Gyrojet, were serious attempts to solve real problems. Others, like the Cobray Terminator, Dardick Revolver, and Duck Foot Pistol, became famous because they were strange, rare, awkward, or far ahead of their time.
Key Takeaways
- Some bizarre guns solved real military, sporting, or industrial problems.
- Proprietary ammunition often hurt strange firearm designs.
- Many weird guns are now collector-only or museum pieces.
- Military pressure created some of history's strangest weapons.
- Odd firearm designs show both creativity and overengineering.
- Weird does not always mean useless.
Walk into any gun store today and you'll see the same familiar lineup. Polymer pistols on one shelf, AR-style rifles on another, pump shotguns lined up neatly, and a row of 1911 variants that all look like cousins. Comfortable. Familiar. A little predictable after a while.
But firearm history has a much wilder side. Rocket pistols. Curved barrels. Glove guns. Magazine-fed revolvers with triangular cartridges. A trap shotgun that looks like it came straight off a movie set. These things actually existed. Some worked remarkably well. Some failed in spectacular fashion. And some became legends just by being so wonderfully strange. This is a look at 18 real firearms that prove gun design has never been a straight path from start to finish.
What Makes a Gun Weird or Bizarre?
A firearm earns the weird label for different reasons. Sometimes it's the shape. Sometimes it's the ammunition. Sometimes the purpose is so specific that it becomes hard to believe the gun existed at all. A weapon designed to shoot around corners or blast slag from an industrial kiln sits in a very different category from your standard bolt-action rifle.
Unusual does not always mean bad, though. Some strange guns solved very real problems. Others failed because the market was not ready, the ammo was too hard to find, or the design was just too complicated for regular use. That tension between clever and impractical is exactly what makes these firearms so interesting to study.
How We Chose These 18 Weird and Bizarre Guns
Every gun on this list actually existed. No rumors, no unverified concepts. Each one has a documented history and a clear reason it ended up here. The selection covers military experiments, civilian oddities, sporting rarities, and industrial tools that technically qualify as firearms. Some were sold commercially. Some lived only as prototypes. Others survive today in auction catalogs and museum display cases.
The 18 Weird and Bizarre Guns
Duck Foot Pistol
The Duck Foot Pistol had multiple barrels spread outward like the toes on a duck's foot. A single trigger fired all barrels at once. Naval officers and prison guards favored it because it could cover a wider area in a single shot, particularly useful in tight, confined spaces against groups.
In an era of slow reloading and close-contact threats, that actually made solid practical sense. Today it looks bizarre. Back then, it was a direct answer to a very specific defensive problem.
Apache Revolver
The Apache Revolver combined a small revolver, a folding knife, and a set of brass knuckles into one compact package. It was popular among the French underworld in the early 1900s. The idea was to handle close-range street threats with a single tool that fit in a coat pocket.
It had no barrel and no trigger guard. Accuracy beyond arm's length was nearly zero. Memorable as a design concept? Absolutely. Practical in most situations? Not really.
Velo-Dog Revolver
This small pocket revolver was designed specifically for cyclists. In late 19th-century France, dogs chasing bicycle riders were a genuine and frustrating problem. The Velo-Dog was designed to protect cyclists from aggressive dogs, typically through the use of small centerfire cartridges intended to stop or deter an attack. The cartridge and concept are generally attributed to Belgian gunmaker Charles-François Galand, with production spreading across Belgium, Germany, Spain, and France.
Some versions fired small centerfire rounds. Others used wax, cork, or even cayenne pepper loads. It sounds funny today, but it solved a real everyday problem for a large number of people at the time.
Gyrojet Pistol
Instead of traditional bullets, the Gyrojet fired small rockets called Microjets. Each projectile gained speed after leaving the barrel, which completely flipped the standard handgun idea upside down. The frame was extremely light and recoil was almost nonexistent.
The problems were significant. Accuracy was poor. Ignition was often unreliable. Ammunition was expensive and hard to find. At contact range the projectile had barely ignited and carried almost no stopping power, a serious problem for any defensive firearm. The design's advantages only materialized at distance, which is the opposite of how most handguns are actually used. A bold concept that the commercial market walked away from very quickly.
Dardick Revolver
The Dardick tried to combine the best parts of revolvers and semi-automatics. It used a fixed magazine and a unique open-chamber rotating system that chambered, fired, and ejected rounds in sequence. The magazine could hold eleven or fifteen rounds depending on the model.
The catch was the ammunition. The Dardick needed triangular cartridges called trounds. That proprietary requirement made adoption nearly impossible. Without a steady supply of trounds, the gun had no practical future regardless of how clever the concept was.
Krummlauf STG-44
The Krummlauf was a curved barrel attachment designed for the German STG-44 rifle during World War II. It was produced in multiple versions with barrel bends of 30, 45, and 90 degrees depending on the intended use, each paired with a periscopic sight. Tank crews used it to defend against attackers without opening a hatch and exposing themselves to fire.
The real-world results were rough. The sharp bend caused severe bullet deformation and occasional fragmentation, reducing accuracy and barrel life. The barrel wore out after roughly 300 rounds. A genuine attempt to solve a deadly problem, but one that never fully worked under battlefield conditions.
Sedgley OSS Glove Gun
This was a single-shot firearm mounted directly onto the back of a leather glove. Developed during World War II for the OSS, the wartime American covert operations agency and predecessor to the CIA, it let the user fire a round at extremely close range by punching an enemy.
It fired a standard .38 S&W cartridge from a single-shot mechanism built into the back of the glove. The entire concept was built around stealth and surprise in tight situations. One of the strangest examples of covert weapon design ever put into production.
Coffee Mill Sharps
A Sharps carbine with a coffee grinder built into the buttstock. This came from the American Civil War era, when soldiers were issued whole beans and had to grind their own coffee in the field. Someone decided combining the two tools made good logistical sense.
The grinder worked poorly and the project was short-lived, with only a small number produced before the concept was abandoned. Authentic examples that survive today are extremely rare and highly valued on the collector market.
Cobray Terminator
The Cobray Terminator was a single-shot 12-gauge shotgun built around the simplest possible design. It was essentially one pipe inside a larger pipe, fired by a fixed pin. The action was a basic slam-fire, open-bolt design where the front pipe slammed rearward to fire. Reloading required manually removing the spent shell by hand.
Recoil was excessive. The metal stock was crude. Commercial reception was poor. It developed a reputation for crude construction, heavy recoil, and limited practical appeal. Somehow that reputation made it fascinating to a whole community of people who appreciate truly odd firearms.
Remington 870 Competition
The Remington 870 is a pump-action shotgun icon. So it comes as a genuine surprise that one version used a gas-assisted recoil-reduction system while retaining the familiar pump-action operating system. The 870 Competition was built specifically for trap shooting, where high-volume sessions make recoil reduction genuinely important over time.
The gas system helped reduce felt recoil, while the shooter still manually operated the pump action between shots. Strange under the 870 name, but practically useful within its narrow sporting role.
Remington 700 EtronX
The Remington 700 is one of the most trusted rifle platforms in American shooting history, so it's genuinely surprising to find such a strange experimental branch on that family tree. The EtronX used electronic ignition powered by a 9-volt battery built into the stock. The firing pin acted as an electrode. Special electronic primers replaced standard ones entirely.
The stated goal was faster lock time and a trigger pull as light as half a pound. Proprietary ammunition killed it. No standard primers meant no long-term market, and the platform quietly disappeared in the early 2000s.
Safari Arms / SASS Rifle-Caliber 1911 System
This system allowed a standard 1911 frame to fire full-power rifle cartridges through a specialized upper receiver. Barrel lengths ranged from ten to fifteen inches. Calibers included heavy rounds like .308 Winchester and 7mm-08. A barrel release mechanism that slid into the mag well allowed single-round breech loading.
It had appeal for specialty handgun hunters and metallic silhouette competitors during the era when rifle-caliber pistols were fashionable. For most people, firing full-power rifle cartridges from a handgun-style frame simply was not something they needed or wanted.
Stoehr Machine Pistol
The Stoehr was a prototype machine pistol chambered in .22 Magnum. It used a metal tape-feed system, where a flexible tape was attached around the rim of each cartridge. The tape and spent cases ejected as the gun fired. The design sat on the forearm and fired in whatever direction you pointed it.
It never progressed beyond the prototype stage. Meaningful aiming was mostly symbolic. Even so, a wearable, forearm-mounted rapid-fire .22 Magnum pistol is a concept that's genuinely hard to forget once you've seen it. Surviving information on the design remains limited.
MAG-7 Shotgun
The MAG-7 was a compact pump-action shotgun with the magazine built into the pistol grip rather than in a traditional tube beneath the barrel. That unusual placement forced designers to create a proprietary short shell measuring 2.36 inches. Original South African versions used a very short barrel and compact overall configuration, though dimensions varied between markets and later variants.
It was designed for extremely close-quarters situations. Proprietary ammunition made wide adoption nearly impossible, and the design never found a sustainable market despite its compact and interesting concept.
OTs-38 Stechkin Silent Revolver
This Russian revolver used captive-piston ammunition. When the cartridge fired, an internal piston pushed the bullet forward. Gas stayed trapped inside the case. No gas escaped through the cylinder gap. The result was a near-silent shot that left almost no evidence behind.
It held five rounds of 7.62mm SP-4 captive-piston ammunition, a specialized cartridge developed specifically for silent firearms. The barrel aligned with the bottom cylinder to reduce recoil, and modern variants added an integrated laser placed over the barrel. A rare example where the ammunition is just as strange and specialized as the firearm itself.
Ljutic Space Gun
This single-shot trap shotgun looked like something off a science fiction film set. It used a pull-and-release trigger, where pulling did nothing until the trigger was released. An internal recoil-reduction system was designed to significantly reduce perceived recoil during competition shooting. The bolt and loading port sat at the bottom of the receiver rather than the top.
It was built in small batches for a narrow niche. Unlike many odd guns, it actually performed extremely well for the purpose it was built for. Surviving examples are now rare and highly valuable on the collector market.
A-Square .577 T-Rex
The .577 Tyrannosaur cartridge was developed in 1993 for stopping dangerous African game at close range. It fired a 750-grain bullet at 2,450 feet per second. Muzzle energy reached 10,180 foot-pounds. Recoil in a 13-pound rifle measured 172 foot-pounds.
For context, a .458 Lott generates around 73 foot-pounds of recoil in the same weight rifle, and that already challenges most experienced shooters. The T-Rex became famous through videos showing shooters losing balance or struggling to control its extreme recoil. A-Square ceased active production operations, and the company effectively folded in the early 2010s, though the cartridge itself remains available through other manufacturers.
Remington MasterBlaster 8-Gauge Kiln Gun
The Kiln Gun was built for steel mills, not ranges or hunting fields. After pouring molten metal, kilns built up thick slag on their inner walls. Workers could chip it away by hand, or they could blast it loose with a specialized shotgun. Early industrial versions ran on 3-gauge shells.
Modern versions use 8-gauge loads, weigh around 220 pounds, fire a 3-ounce slug at 1,750 feet per second, and have a useful service life of 250,000 rounds. A firearm built specifically to clean industrial equipment earns its spot on any weird guns list without any argument.
Quick Comparison: Which Weird Guns Were Actually Practical?
| Gun | Main Role | Why It Was Weird | Practical Outcome |
|---|---|---|---|
| Remington 870 Competition | Trap shooting | Gas-assisted recoil-reduction pump shotgun | Practical but niche |
| Ljutic Space Gun | Trap shooting | Futuristic single-shot design | Practical niche success |
| Gyrojet Pistol | Experimental firearm | Rocket ammunition | Commercial failure |
| Dardick Revolver | Civilian experiment | Magazine-fed revolver with trounds | Commercial failure |
| Krummlauf STG-44 | Military experiment | Curved barrel | Limited battlefield practicality |
| Cobray Terminator | Civilian shotgun | Crude single-shot design | Poor commercial reputation |
Not every weird gun was useless. Some performed well in narrow roles. Others failed because they were too complicated, too expensive, or too dependent on special ammunition that buyers simply could not source anywhere.
Why So Many Weird and Bizarre Guns Failed
Proprietary ammunition is the fastest way to sink a firearm platform. If buyers can't find ammo at a normal store, most of them won't buy the gun. Complex mechanisms made maintenance harder than it needed to be. Some designs fixed one problem and immediately created three new ones in the process.
Military experiments often came from urgent battlefield needs with no time for long-term market testing. Civilian buyers tend to prefer familiar handling, available parts, and ammo they can buy off a shelf. Interestingly, collector value often rises sharply after a strange gun fails commercially, which adds an ironic layer to the whole story.
Are Any of These Weird Guns Still Available Today?
Most are not normal new-production firearms. Some appear at auction houses, in private collections, or behind museum glass. Others survive only as documented prototypes. Availability depends heavily on local laws, classification, condition, and what you are willing to spend on a rare piece.
Anyone interested in buying, restoring, or firing a rare or antique firearm should verify applicable laws and get an inspection from a qualified gunsmith before doing anything further.
What These Strange Firearms Teach Us About Gun Design
Firearm design is always a balance between creativity and practicality. The best designs solve a real problem without creating new ones in the process. Weird guns tend to fail when they demand special ammunition, complex maintenance, or a steep learning curve that most people have no interest in climbing.
Some odd designs still matter because they pushed engineering into territory nobody had explored before. Others are remembered simply because they were bold and beautifully impractical. The dead ends in firearm history are often the most interesting stops along the way.
Final Thoughts
These 18 guns prove that firearm history is not a straight line from point A to point B. Some were practical tools built for very specific jobs. Some were wartime experiments born from desperation. Some were sporting oddities with small but devoted followings. Some were commercial disasters that became collector legends entirely because of how strange they were.
The thread connecting all of them is simple: somebody studied a problem hard and came up with an answer that surprised everyone. Explore more ProArmory firearm history and gear guides for deep dives into the guns that made history, broke the rules, or simply refused to be forgotten.
Frequently Asked Questions (FAQs)
What is the weirdest gun that actually existed?
The Gyrojet Pistol, Dardick Revolver, Duck Foot Pistol, and Krummlauf STG-44 are among the strongest candidates. The answer depends on what weird means to you. Strange ammo, strange shape, and strange purpose are all fair categories, and each of those guns wins at least one.
Were weird and bizarre guns actually useful?
Some were genuinely useful in narrow roles. The Remington 870 Competition and Ljutic Space Gun worked well for trap shooting. The Krummlauf and OTs-38 were designed for specialized military and covert needs. Others failed because they were awkward, unreliable, or too expensive to sustain in any real market.
Why did many bizarre firearms fail?
Proprietary ammunition was the most common cause. Complex mechanisms, high cost, limited demand, strange handling, and poor market support all played a role depending on the specific design.
Can collectors still buy these weird guns?
Some appear at auctions or through private collections. Many are rare, discontinued, antique, prototype-only, or legally restricted. Always research applicable laws and consult a qualified professional before pursuing any rare firearm.
Are old or unusual firearms safe to shoot?
Older and rare firearms should always be inspected by a qualified gunsmith before firing. Some were built for obsolete ammunition that no longer exists. Many are better preserved as collector pieces than taken out to the range.
