Firearms from WikiPedia:

A firearm is a device which projects either single or multiple projectiles at high velocity through a controlled explosion. The firing is achieved by the gases produced through rapid, confined burning of a propellant. This process of rapid burning is technically known as deflagration. In older firearms, this propellant was typically black powder, but modern firearms use smokeless powder, cordite, or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability.

While most firearms are primarily used as weapons, some exist that are used primarily as tools.

In the Middle Ages the term "firearm" was used in English to denote the arm in which the match was held that was used to light the touch hole on the hand cannon.
