Which type of malfunction occurs when a semi-automatic pistol fails to extract the spent cartridge?

When a semi-automatic pistol fails to extract the spent cartridge, it results in a malfunction known as a stovepipe. This issue specifically occurs when the spent casing is not ejected from the action, causing it to become lodged vertically in the ejection port, resembling a stovepipe. This blockage prevents the next round from being fed into the chamber, resulting in a failure to continue firing.

Understanding this malfunction is critical for law enforcement officers and firearms users, as the resolution often involves clearing the obstruction by manually removing the casing before resuming fire. Proper training in identifying and addressing this type of malfunction ensures that officers can maintain operational readiness and safe handling of their firearms.

The other options refer to different types of malfunctions. Misfire refers to a situation where the cartridge fails to fire altogether due to issues such as a bad primer. Double feed occurs when two cartridges try to enter the chamber simultaneously, obstructing the action. Feed failure involves the inability of a round to be fed into the chamber, often due to issues with the magazine or feed ramp. Each of these malfunctions has different causes and requires different techniques for resolution, underlining the importance of understanding various firearm issues thoroughly.
