Tactical guns are pistols, rifles, and shotguns configured for defensive and high-pressure use. They accept accessories via rail systems (optics, lights, foregrips), and are typically chambered in practical defensive calibers such as 9mm, .223 Remington, or .308 Winchester. Common features include adjustable stocks, extended magazines, enhanced sights, and aftermarket grips or triggers. Many include compensators or muzzle devices to manage recoil. Frames and receivers are usually polymer or alloy for corrosion resistance. Tactical guns are used by law enforcement, military, and civilian shooters for defense and recreational range use.
