5 - Key Gun
The key gun was kept by the side of Jailers in the 17th century and used if a prisoner tried to break out of his cell. The key guns small size was a big plus point and the surprise factor of a key being a deadly weapon would catch a lot of criminals off guard .
The negative point about this gun is that it only held one bullet in the chamber so if the shooter missed they were most likely beaten to death by the inmates
4 - Pepperbox Gun
The pepperbox gun was very popular in the 1800's it was primarily used as a backup gun and could kill multiple targets during one shooting session. It 'could' kill multiple targets only if the gun didn't weigh so much making aiming a struggle for the user. The barrel had to be hand rotated to take the next shot, making life even more difficult for the shooter.
3 - Harmonica Gun
This is a gun which you don't want to put anywhere near your mouth. Named the harmonica pistol due to its elongated barrel sticking horizontally out of its side, it produces anything other than music for hillbillies. There are obvious drawbacks with this gun reloading was very slow as each bullet had to be inserted into the chamber individually. A lot like most of the other weird guns on this list aiming was problematic as the long and heavy barrel made it difficult for the shooter to aim the gun.
2 - Duck's Foot Pistol
This would be the perfect gun if you came across four villains walking slowly towards you perfectly aligned a metre apart from each other. Alas, those situations are not something the average bandit would come across making the Duck's Foot pistol a useless weapon to lug around. The weapon was used in the 18th century by police officers during riots when aiming isn't very necessary, similar to police today.
1 - 48-Shot Revolver
AHHH THE MONSTROSITY!!! What was the inventor thinking? Why? This is clearly more style than substance. The shooter would need an hour to reload this thing and then a backpack to carry it around. You know you're over compensating when the gun weighs more than the dead body the gun is meant to leave behind.
The gun was patented in 1855 by British gun enthusiast Joseph Enouy. The revolver has 8 sperate cylinders which are spun on a rod and each cylinder can hold 6 bullets which can also be spun. For making weird guns, creativity is key, aiming not so much, again similar to the other weird guns aiming was an afterthought as the weight of the guns made it almost impossible to aim at a target.
