Sidearm

A sidearm is a personal defense weapon, usually a pistol or another melee weapon, which is worn on the body in a holster to permit immediate access and use. Usually, uniformed personnel wear their weapons openly, while personnel in civilian attire have their weapon concealed under their clothes. A sidearm may be carried alone, or as a back-up to a primary weapon such as a rifle or carbine.
