firearm

A firearm is a device designed to launch projectiles, typically bullets, using controlled explosive energy from gunpowder. It consists of components like the barrel, where the projectile is fired from, and a mechanism—such as a trigger—that ignites the gunpowder to propel the bullet forward. Firearms come in various types, including handguns, rifles, and shotguns, serving purposes from self-defense and sport to law enforcement. They are regulated by laws to ensure safe handling and to prevent misuse, emphasizing responsible ownership and use.
