I tend to agree with Beaver Jack on this . A weapon is an implement of war whether used in a foreign land or during a burglary/robbery assault in an urban environment. A rifle/bow is a tool for the humane harvesting of a game animal.

And I quote from Encyclopedia Britanica:

[quote][an instrument used in combat for the purpose of killing, injuring, or defeating an enemy. A weapon may be a shock weapon, held in the hands, such as the club, mace, or sword. It may also be a missile weapon, operated by muscle power (as with the javelin, sling, and bow and arrow), mechanical power (as with the crossbow and catapult), or chemical power (as with the rocket and missile and such guns as the cannon, rifle, and pistol). Weapons may also be classified as conventional, destroying by kinetic energy (as with the bullet) or by chemical energy (as with the bomb and grenade). The nonconventional category comprises nuclear weapons, such as the atomic bomb and thermonuclear bomb, as well as weapons of chemical warfare and biological warfare. All the aforementioned are offensive weapons, but such defensive measures as fortification, armour, and the helmet have also been considered weapons.
