A gun is a weapon that uses explosive force to propel a projectile, typically a bullet, at high speed. Guns come in various types, including handguns, rifles, and shotguns, each designed for different purposes such as self-defense, hunting, or sport shooting. They operate by igniting gunpowder or other propellants within a chamber, which creates gas that pushes the bullet out of the barrel. Guns are often associated with discussions about gun control, firearm safety, and violence prevention. In many countries, laws regulate their ownership and use to promote safety and reduce crime. Understanding the mechanics and responsibilities of gun ownership is essential for users and society.
