A weapon fired by striking the primer is known as what?

• A. Firing Pin
• B. Percussion Fire
• C. Solenoid
• D. Semi-Automatic

Answer: (B)

Ignition by impact on the primer is called percussion fire. In this method, the primer, a small explosive in the cartridge, is detonated when struck by the firing mechanism (like a hammer or firing pin). That detonation flashes into the main powder charge, producing the high-pressure gas that drives the bullet forward. The term percussion fire specifically describes this impact-initiated ignition. The other options don’t fit the described mechanism: the firing pin is a component that delivers the strike but isn’t the firing method itself; a solenoid is an electronic actuator not typically used for percussion ignition; and semi-automatic refers to how the gun cycles the next round, not how the current round is ignited.
