The primary components include a barrel, which guides the projectile's trajectory, a firing mechanism to initiate the launch, and a means of containing and directing the propellant energy. Firearms can be broadly categorized into handguns, rifles, and shotguns, each serving distinct purposes. The evolution of firearms spans centuries, with advancements in design, materials, and technology contributing to their effectiveness and versatility. From early gunpowder-based firearms to the sophisticated models of today, the history of firearms is intertwined with military, sporting, and cultural developments across the globe.
