Top 10 Worst Guns Ever Made

Top 10 Worst Guns Ever Made

Top whatever lists are a great way to start an argument. When it comes to the top 10 worst guns ever made of all time, the only argument is why a certain gun was left off. 

Here are the criteria: 

1) Most or all of the production line is serious junk. Every gun maker can produce a bad one every now and then. 

2) Mass produced is a requirement. No one-off or wildcats allowed. 

3) Poor design, bad ammo or a combination is a must. 

4) The gun has to have an intended practical application, be that military, hunting, target or defense. 

Here are the top picks for the worst guns ever made

10) The Gyrojet 


In some cartoons, when a gun is fired, the barrel expels the brass and projectile as a complete unit. The Gyrojet actually made this happen. It did not work very well. Made in a handgun and a carbine with an inexplicably flared barrel (think blunderbuss), the Gyrojet used proprietary ammo. The first version was a 13mm which put the gun into the "destructive device" category. Later models were 12mm. Taufledermaus got to shoot one of these guns and the slo-mo footage shows why this gun just never lived up to the hype.

It is actually a decently made firearm, but the ammo problems put it on the worst guns ever made list. 

9) Zip 22 

Zip 22 

US Firearms went out of business after producing the Zip .22 autoloader. This is a prime example of a good concept poorly executed. As Forgotten Weapons says, this is a gun "that can't be forgotten quickly enough." 

8) Cochran Turret Revolver 

Cochran Turret Revolver 

When Colt came out with the revolver in 1830, other companies tried to compete with repeating handguns. Cochran Turret Revolver is not the only turret firearm ever made, but earns a spot on the list for being the worst. The problem with turret guns in black powder is the cylinder points everywhere. A chain fire means bullets spray in a circle, including back at the shooter. 

7) FP-45 Liberator 

FP-45 Liberator 

The FP-24 Liberator is a single-shot .45 ACP mostly made from sheet metal, stamped, folded and stuck together. It ranks as one of the best ideas ever or worst guns ever made, depending on who does the reviews. It is among the worst guns ever made because of seriously cheap construction and the way it shoots. Spent rounds were pushed out with a stick. It is an awesome concept because it was cheap. It was meant to be a concealed weapon for partisans behind enemy lines. Many were dropped from planes in hopes resistance fighters could use them. 

6) Nambu Type 94 

Nambu Type 94 

In WWII the Japanese cranked out some fine weapons like the Arisaka. The Nambu Type 94 semi-auto handgun is not one. Slap it on the side hard enough, it will go off with one in the chamber. Slap the magazine in too hard, it falls out. It will fire before fully chambering a round. 

5) Street Sweeper 

Street Sweeper  

Most people in the West know the Armsel Striker as the Street Sweeper, the US version produced by Cobray. The sole grace of the original is it held 12 rounds of 12 gauge. "Its rate of fire was easily eclipsed by even the most carbon-fouled Remington 1100," writes Grant Cunningham. Given the time needed to reload, even a SXS can run through a box of shells faster than the Sweeper. 

The Sweeper was declared an NFA item because the BATF ruled it has no reasonable hunting or sporting purpose. The BATF is correct. 

4) Colt 1855 

Colt 1855 

Cylinder rifles have sort of made a comeback; see the Cimarron and the Circuit Judge. They are not very popular. The Colt Model 1855 tried to make this a standard 150 years ago. It didn't. Burning powder and hot gasses from the cylinder gap so close to the face made this a disturbing shooter. It even came in a 10 gauge

3) Breda Modello 30 Light Machine Gun 

Breda Modello 30 Light Machine Gun 

The Breda is an Italian-made machine gun from WWII. On a clean range, it was great. In trenches, surrounded by mud, dust and soldiers returning fire, not so much. It had so many openings to allow dirt in that it jammed frequently. Owing to the problems with chambering new rounds, an oil injector lubed each case as it moved into firing position. Oil buildup attracted more dirt. The oil also got hot - no way to keep it cool - and could cause out of battery ignition because of the heat. 

2) The Rohm RG10 

Rohm RG10 

Saturday Night Special, thy name is Rohm RG10. This German-made .22 Short revolver is routinely ranked as the world's worst modern revolver. Firing the already anemic .22 Short, this gun will ONLY shoot the Shorts. The manufacturing was so shoddy parts often broke off. The cylinder on many will freely spin, meaning the cylinder and the barrel do not always line up properly. The Rohm is known spit lead fragments out the sides because of this. 

The RG 10 is in a near tie for the worst guns ever made with the No. 1 gun. 

1) The Chauchat 


Check any Worst Guns Ever and the Chauchat is always at the top or near the top. The first editions of the French-made light machine gun from WWI were so bad soldiers often threw it away. It was so badly made, parts were often not interchangeable. It was prone to jam. Loading the banana mags was an exercise in precision work because if the rounds were not inserted just so, it would not feed. 

American Rifleman says the rep is not deserved and points to a handful of stories from the wars as well as their own experience shooting a Chauchat. Note the AR shooting was done on a range and not under combat conditions. Even so, they had issues. 

Other people say the Chauchat gets a bad rap. That may be. However, Rock Island Auction sold one in 2011. The winning bid is not listed, but with a top estimate of $4,500 for a full-auto rifle, that should tell you everything you need to know about this gun.
