Firearm
A firearm is a portable gun (a Gun barrel">barreled ranged weapon) that inflicts damage on targets by launching one or more projectiles driven by rapidly expanding high-pressure gas produced by exothermic combustion (deflagration) of propellant within an ammunition cartridge. If gas pressurization is not achieved via propellant combustion but through mechanical gas compression, then the gun is technically an air gun, not a firearm. The first primitive firearms originated in 10th-century China when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears into the one-person-portable fire lance,, which was later used as a shock weapon to good effect in the Siege of De'an. In 13th century, the Chinese invented the metal-barrelled hand cannon, widely considered to be the true ancestor of all firearms
