What are the major forms of malfunctions?

• A. Gun Stoppage; Misfire; Hang Fire; Cook Off; Runaway Gun
• B. Gun Stoppage; Misfire; Hang Fire; Cook Off
• C. Misfire; Hang Fire; Cook Off; Runaway Gun
• D. Hang Fire; Cook Off; Runaway Gun; Gun Stoppage

Answer: (A)

The major forms of malfunctions cover five scenarios that describe the main ways a gun can fail to operate properly: gun stoppage, misfire, hang fire, cook off, and runaway gun. Gun stoppage means any failure that prevents the gun from firing or cycling—like feeding, chambering, extracting, or ejecting a round, or the action not cycling as it should. It’s the broad category for jams and feeding/extraction problems. Misfire is when the cartridge primer fails to ignite when the trigger is pressed, so no discharge occurs at all from that attempt. Hang fire is a delay between pulling the trigger and ignition of the round. The primer fires, but the main charge ignites after a short delay, which can be dangerous if you don’t keep the weapon pointed in a safe direction. Cook off happens when a chambered round ignites due to overheating of the firearm from sustained firing. The heat causes the cartridge to ignite independent of the trigger pull. Runaway gun is when the weapon continues to discharge uncontrollably, often after the trigger has been released, due to a mechanical fault in the fire control or sear system. The option that lists all five categories is the best answer because it fully captures the range of major malfunctions a shooter must recognize and respond to.
