What is NOT a step in the functioning sequence of a firearm?

In the functioning sequence of a firearm, steps typically include components like feeding, locking, firing, and ejecting. "Storing" does not fit into this sequence because it refers to the act of keeping or securing a firearm rather than a mechanical or operational action performed by the firearm during its firing cycle.

Feeding involves the mechanism that introduces ammunition into the chamber, locking secures the bolt or slide in place to ensure the firing mechanism is ready, and ejecting expels the spent cartridge casing after firing. These steps are crucial in the operational cycle of a firearm and ensure it operates correctly and safely. Storing, on the other hand, is not part of this operational process but rather pertains to the management and safety practices surrounding the handling of firearms.
