What is the term for a malfunction where there is a delay after the trigger is pulled before the firearm fires?

The term for a malfunction where there is a delay after the trigger is pulled before the firearm fires is referred to as a "hang fire." In this situation, the firing mechanism is activated, but the round does not fire immediately. Instead, there can be a noticeable delay, sometimes a few seconds, before the cartridge ignites. This can occur due to a variety of reasons, such as a faulty primer or inadequate ignition of the propellant.

Understanding this concept is crucial for firearm safety, as a hang fire can present a dangerous situation. If an individual experiences a hang fire, it is essential to keep the firearm pointed in a safe direction and wait for a specified amount of time before checking the chamber, as the round may fire unexpectedly.

Other terms like a jam refer to a blockage within the firearm preventing it from cycling properly, while a misfire typically indicates that the firearm failed to fire when the trigger was pulled, often due to issues with the cartridge itself. A foul relates to the buildup of residue in the barrel or action of the firearm, affecting performance but not directly concerning the firing delay like a hang fire does.
