Guns are tools designed to project force against a target, typically using a projectile like a bullet. They operate by igniting gunpowder or other propellants to create a rapid expansion of gases, which propels the projectile out of a barrel. Guns come in various types, including handguns, rifles, and shotguns, each serving different purposes such as self-defense, hunting, or sport shooting. The use of guns is regulated in many countries, with laws governing their ownership, sale, and use. Safety measures, such as proper training and secure storage, are essential to prevent accidents and misuse. Discussions about guns often involve topics like gun control, firearm safety, and the impact of guns on society.
