👉 The key weapon, often referred to as the primary or main weapon in a firearm, is the component designed for delivering projectiles or ammunition. Typically, it consists of a barrel that channels the fired cartridge, a hammer mechanism that propels the bullet or shell forward upon firing, and a firing pin that strikes the primer to ignite the propellant. The key weapon's design and materials are crucial for accuracy, range, and overall performance. Variations exist across different types of firearms, such as pistols, rifles, and shotguns, each optimized for specific uses and environments.
