What component strikes the primer of a cartridge to initiate firing?

The firing pin plays a crucial role in the process of firing a cartridge. When the trigger is pulled, it activates the firing mechanism, which causes the firing pin to move forward with speed and force. As the firing pin strikes the primer of the cartridge, it creates a small but powerful spark. This spark ignites the gunpowder inside the cartridge, leading to the firing of the bullet.

The design of the firing pin is specifically intended to deliver a precise impact on the primer, ensuring reliable ignition. Its correct functioning is essential for the firearm to operate safely and efficiently. In many firearms, the firing pin is a small, cylindrical piece made of durable material that can withstand repeated impacts.

Other components, such as the trigger and hammer, are important in the firing sequence but do not strike the primer directly. The action refers to the overall mechanism that houses these components and cycles the firearm, but it is the firing pin that is directly responsible for initiating the ignition of the cartridge.
