Which term describes a malfunction where the cartridge fails to eject cleanly, sometimes causing a jam?

• A. Misfire
• B. Hang fire
• C. Squib
• D. Stovepipe

Answer: (D)

In semi-automatic firearms, the action must properly eject the spent case after firing. When the cartridge case doesn’t clear the ejection port cleanly and instead sticks upright, it can block the path and cause a jam. That specific scenario is described by the term stovepipe—the spent case stands in the ejection port like a stovepipe. This distinguishes it from other ignition or power issues: a misfire means the primer didn’t ignite at all, a hang fire is a delayed ignition after pulling the trigger, and a squib is a low-power round where the bullet doesn’t exit the barrel. So stovepipe best fits the described malfunction because it centers on defective ejection rather than ignition or velocity problems. Common causes include a weak extractor, a dirty or dirty-chambered gun, a weak recoil spring, or grip that doesn’t cycle the action properly; addressing these and ensuring clean, functioning components helps prevent stovepipes.
