If you don't have to worry about hingry predators, large ones like bears or wolves, tigers and lions, I think an axe and a saw for fire and construction wood is a better alternative than a gun.
EDIT: Hunting, a gun can be used for hunting. If you know how to, if you don't it's still pretty useless.
