Which of the following is part of the firing cycle of a semi-automatic firearm?

In the firing cycle of a semi-automatic firearm, the extraction phase is crucial because it involves removing the spent cartridge case from the chamber after a round has been fired. This process is essential for the firearm to prepare for the next round to be loaded into the chamber.

During the operation of a semi-automatic firearm, when the trigger is pulled, the firing pin strikes the primer of the cartridge, igniting the gunpowder and propelling the bullet down the barrel. Once the bullet exits the barrel, the rapid expansion of gases pushes the spent cartridge back against the extractor. The extractor grips the rim of the cartridge case, pulling it out of the chamber as the slide moves back.

Following the extraction, the cycle continues with the ejection of the spent casing followed by the loading of a new cartridge. Understanding this sequence is important for operating a semi-automatic firearm safely and efficiently, ensuring reliability in performance.
