What is the function of the ejector in a semiautomatic firearm?

The function of the ejector in a semiautomatic firearm is to eject the spent cartridge from the weapon. When a round is fired, the action chamber opens, and the spent casing needs to be removed to make way for the next round to be chambered.

The ejector performs this crucial role by striking the spent cartridge case as the slide moves backward, effectively pushing it out of the ejection port. This ensures that the firearm can continue to cycle and prepare the next round for firing without interruption. The ability to efficiently eject spent cartridges is vital for the reliable operation of a semiautomatic firearm, contributing to its overall performance and functionality.

Understanding this function also highlights the role of other firearm components: while the extractor is responsible for grasping the cartridge case as the slide moves back, the ejector ensures that the case is expelled from the firearm, allowing for the seamless operation of loading new ammunition from the magazine into the chamber.
