Which of the following describes a double feed malfunction?

A double feed malfunction occurs when two rounds of ammunition are present in the chamber, which prevents the firearm from functioning properly. This typically happens when the bolt, or slide, tries to strip a new round from the magazine while another round is still in the chamber. As a result, instead of one round being fed into the chamber for firing, the firearm experiences a blockage due to the two rounds occupying the same space.

This type of malfunction requires specific corrective actions to clear it, which often involves locking the slide to the rear, removing the magazine, and clearing the chamber to ensure that only one round is present before reloading and continuing to engage. Understanding this malfunction is essential for proper firearm operation and safety, allowing law enforcement officers to respond effectively during critical situations.
