Which cycle of function involves preparing the firearm to fire?

The cycle of function that involves preparing the firearm to fire is known as cocking. This phase is critical in firearms operation as it sets up the firing mechanism for impending discharge. During the cocking phase, the hammer or striker is drawn back and held in a position of readiness, which is essential for activating the firing pin when the trigger is engaged.

In contrast, chambering refers to the process of loading a cartridge into the chamber of the firearm, while locking involves securing the bolt or slide in the closed position to ensure the firearm is ready for firing without any risk of accidental discharge. The firing phase is when the trigger is pulled, resulting in the hammer or striker being released to strike the firing pin, initiating the firing sequence. Understanding the distinct functions of each cycle helps in grasping the overall mechanics of firearm operation.
