=Modern definition= A sidearm is a small personal weapon that is typically worn on the body in a holster in such a way to permit immediate access and use. Although this term can apply to swords and other melee weapons, the modern use of it is usually affiliated with pistols and similar firearms that can be used with ease, most only requiring one hand.
