Which characteristic is true for a semi-automatic action?

A semi-automatic action is designed to automatically eject a spent cartridge and chamber a new round after each shot is fired, allowing for quicker successive shots without the need for manual loading. This mechanism enhances efficiency and maintains the shooter’s focus on aiming, as the action of reloading does not require additional effort.

The other characteristics mentioned do not accurately describe semi-automatic actions, as they either pertain to manual actions or misrepresent the function of semi-automatics. For instance, a semi-automatic does not require manual loading after each shot, which is a feature of manual actions. Additionally, while semi-automatics can be found in both rifles and handguns, they are not exclusively used in rifles, and the perception of recoil can vary based on numerous factors beyond just the action type.
