9. Duck Foot Pistol
The duck foot pistol, which first appeared in the 1700s and 1800s, was named after the shape of its barrels, which looked like the foot of a duck.
This gun could have as few as three barrels and as many as six. Usually, each barrel was aimed in a different direction.
The principle behind this type of pistol is one of confrontation by one person against a group.
For example, the gun was designed for use by people like bank guards, prison wardens, and ship captains who could be attacked by several people coming from different directions.
