What does pulling the trigger of a firearm cause to strike and explode the primer?

• A. The firing pin
• B. The cartridge
• C. The breech
• D. The hammer

Answer: (A)

When the trigger of a firearm is pulled, it activates the mechanism that releases the firing pin. The firing pin is a small, metal rod that strikes the primer of the cartridge. This impact generates a spark that ignites the gunpowder within the cartridge, leading to the discharge of the bullet. In this context, the firing pin is a critical component in the firing sequence of a firearm. Its role is to deliver a precise strike to the primer, ensuring that the ignition process occurs effectively. Understanding the function of the firing pin is essential for grasping the basic mechanics of how firearms operate.
