Which malfunction describes a pump action failing to hold the next round?

The malfunction that describes a pump-action shotgun failing to hold the next round is best identified as a “Short Stroke.” In the context of pump-action firearms, a “Short Stroke” occurs when the shooter does not fully operate the action of the pump, resulting in the bolt not moving completely back or forward. This incomplete motion prevents the next round from being fed into the chamber properly.

Understanding this malfunction is crucial because it typically arises from user error rather than a mechanical failure. It emphasizes the importance of fully cycling the action for reliable function, especially in high-stakes situations where every shot counts. Recognizing a “Short Stroke” is vital for troubleshooting and improving a shooter's technique to ensure consistent and reliable operation of the firearm.
