Gun

A gun, is a normally tubular weapon or other device designed to discharge projectiles or other materials. It launches one or more projectiles, or bullets, often driven by the action of an explosive force. The explosion inside the gun tends to shake the user's hands and reduce accuracy, the process being called recoil. This forces a user to grip the weapon in a certain way and have train on how to use it more efficiently. This weapon is often used in Marksmanship.

Today, guns are used primarily for hunting and for sport, as well as for war and policing. Slade Wilson as Deathstroke, Chien Na Wei as China White, and Lyla Diggle as Harbinger all prefer to use this type of weapon. Some guns come in the form of portable, handheld firearms.
