Non-Restricted Firearms Course Practice Test

The firing pin strikes the primer in the first step of the firing sequence. This step is crucial because it initiates the process that leads to the ignition of the cartridge. When the shooter pulls the trigger, it releases the firing mechanism, allowing the firing pin to move forward with force. The impact of the firing pin on the primer causes the primer to ignite, which then ignites the propellant inside the cartridge. This is an essential part of firearm operation, as without the firing pin striking the primer, the cartridge would not fire, and the sequence would not progress to subsequent steps such as the bullet being propelled down the barrel. Understanding this step is vital for grasping the mechanics of how firearms function safely and effectively.
