Pistols are small firearms intended to be used with one hand. In the 15th century the term "pistol" was used for small knives and daggers which could be concealed in a person's clothing. By the 18th century the term came to be used exclusively to refer to hand-held firearms. The handgun is the most moral of all firearms, in the sense that it may be readily employed to eliminate criminals, corrupt politicians, dictators... and demons.
