Consistency in how a spent case is expelled comes from how reliably the extractor grabs the cartridge rim and how the ejector directs the case as the slide cycles. When the extractor’s fit and geometry match the rim well, it pulls the case out in a controlled, repeatable motion. The ejector then provides a consistent push at the right location and angle, giving the case a predictable path out of the gun. If either component is worn, bent, or misaligned, the case can slip, tilt, or be ejected at varying angles or speeds, producing irregular patterns like stovepipes or unpredictable ejection.

Other factors—such as chamber geometry, recoil spring strength, or the presence of additional extractor/ejector springs or plungers—can affect timing, reliability, or feel, but the primary determinant of a consistent ejection path is the fit and geometry of the extractor and ejector.
