What happens during the 'cocking' phase of a shotgun's cycle of operation?

During the 'cocking' phase of a shotgun's cycle of operation, the primary action that occurs is the resetting of the firing pin for the next shot. This process is crucial because it prepares the firearm for subsequent firing by ensuring that the firing pin is in the correct position to strike the primer of the next cartridge when the trigger is pulled.

In a shotgun, the cocking phase typically follows the firing of a round. After the cartridge is discharged, mechanisms such as hammers or strikers are returned to their original position, allowing the firearm to be ready for the next trigger action. This is essential for the functionality and safety of the weapon, as a correctly reset firing pin ensures that the gun will fire only when intended.

Other options like loading a shell into the chamber or pulling the trigger refer to different stages in the operation of a shotgun and do not take place during the cocking phase. Cleaning the barrel is unrelated to the cycle of operation and is part of maintenance rather than firing or reloading the weapon.
