The three pistol malfunctions?

• A. Failure to fire, stove pipe, and double feed.
• B. Jam, misfire, and feed obstruction.
• C. Failure to eject, misfeed, and cook-off.
• D. Stove pipe, double feed, and misfire.

Answer: (A)

Pistol malfunctions are commonly grouped by what goes wrong: ignition, feeding, and ejection. The three for this item are failure to fire, stove pipe, and double feed.

Failure to fire means the primer didn’t ignite when the trigger was pulled—the round won’t chamber or fire, so the shooter must address the issue and re-engage. A stove pipe is an ejection-related jam where the cartridge case is pulled out but caught in the ejection port, leaving a portion of the slide unable to close and forcing the shooter to clear the obstruction and reseat the slide. A double feed occurs when two cartridges try to feed into the chamber at once, creating a jam that blocks operation and requires clearing.

These three cover the main categories: ignition problems, a feeding problem (double feed), and an ejection problem (stove pipe). Other terms like misfire, feed obstruction, jam, or cook-off either describe overlapping or less specific situations, or refer to more extreme or different scenarios, so they don’t form the standard, concise trio the question is asking about.
