In the M500 shotgun, which component is associated with the PPF?

• A. Firing pin
• B. Extractor
• C. Disconnector
• D. Hammer

Answer: (C)

The PPF-related function is about timing the trigger release with the action’s cycling, so a shot can only occur once per trigger pull. The disconnector is the part that makes this happen: it holds the hammer back (or prevents it from dropping) until the action has fully cycled and the trigger has been reset. In a Mossberg 500, when you pull the trigger, the trigger/sear interaction starts the firing sequence, but the disconnector temporarily blocks the sear from releasing the hammer until the bolt cycles and the trigger is re-pressed. This coordination ensures a controlled, single-fire event per cycle and prevents a second discharge if the trigger is still in the rearward position. The other components—firing pin, extractor, and hammer—don’t manage this cycle-timing role: the firing pin lights off the primer, the extractor removes spent cases, and the hammer provides the strike but doesn’t regulate safe, single-shot timing.
