👉 A sold weapon, also known as a firearm or gun, is a type of weapon that fires projectiles, typically bullets, from a barrel. Sold weapons are designed for military, law enforcement, and sometimes civilian use, featuring various components such as a barrel, chamber, trigger mechanism, and often sights for aiming. These weapons can be handheld or mounted on vehicles or other platforms, and they operate using a process of firing a projectile when triggered by pulling back the trigger. Sold weapons come in numerous calibers and are regulated by laws and regulations that vary by country, dictating their use, storage, and handling.
