The part of a typical semi‑automatic pistol that actually kicks the spent case out is the ejector , working together with the extractor and the ejection port.

Core answer

  • The extractor is a small hooked piece (usually in the slide) that grabs the rim of the cartridge and pulls the empty case out of the chamber as the slide moves backward.
  • The ejector is a fixed projection on the frame that the case hits as it is pulled back; this impact pivots the case out through the ejection port , throwing the spent case clear of the pistol.

So, in simple terms:

  • The extractor pulls the case out.
  • The ejector knocks it sideways and out.

If the question is asked in the same style as basic firearm safety or exam material (like many “check your understanding” questions), the expected one‑word part that “ejects the spent case” is usually the ejector.
