A hand cannon is a type of early firearm that was designed to be held and fired with one hand. Originating in the late Middle Ages, these weapons were typically made of metal and featured a simple design, often using a matchlock or flintlock mechanism to ignite gunpowder. Hand cannons were among the first portable firearms, allowing soldiers and civilians to wield significant firepower. These weapons were often used in battles and duels, providing a new level of personal defense. Over time, hand cannons evolved into more advanced firearms, leading to the development of modern pistols and revolvers. Their historical significance is notable in the evolution of firearms technology.
