What is the primary function of the hammer in a firearm?

The primary function of the hammer in a firearm is to strike the primer for ignition. When the trigger is pulled, the hammer moves forward and impacts the firing pin, which then strikes the primer of the cartridge. This impact causes a small explosion that ignites the gunpowder, leading to the firing of the bullet. Understanding this mechanism is crucial for firearm operation and safety, as it highlights the importance of proper handling and the sequence of operations in firing a weapon. The hammer plays a vital role in ensuring that the ignition of the ammunition occurs as intended, making it a critical component in the functioning of both modern and traditional firearms.
