In a failure-to-eject scenario, what visually indicates a jammed slide?

In a failure-to-eject scenario, a jammed slide can be visually indicated by the casing standing straight up. This specific condition often occurs when a spent casing does not properly eject from the chamber and remains in the way of the slide’s forward movement. When the casing is in this position, it prevents the slide from advancing back to its original position, resulting in a jam that can be visually recognized by the upright casing.

Other indicators, such as the slide being locked back or the bullet being partially loaded, refer to different mechanical states of the firearm and do not specifically indicate a jammed slide. Similarly, an empty magazine does not directly correlate to a failure-to-eject, as a firearm can still malfunction with a magazine that has rounds in it. Recognizing the visual signal of the casing standing straight up is crucial for a clear diagnosis of the issue at hand during firearm operation.
