What is a class 4 malfunction defined as?

In firearm terminology, a class 4 malfunction specifically refers to a situation where the firearm is out of battery. When a firearm is out of battery, it means that the slide or bolt is not fully in the locked position, which prevents the weapon from firing. This condition often occurs when the action is not completely closed and secured before the trigger is pulled, leading to a failure in the firing process.

Understanding this malfunction is critical for law enforcement officers, as it directly relates to the safe and effective operation of their firearm. Recognizing an out-of-battery condition allows the officer to take appropriate corrective measures, ensuring both safety and functionality in critical situations.

The other types of malfunctions mentioned—misfire, double feed, and failure to eject—are distinct issues each with their own definitions and solutions, which further clarifies that a class 4 malfunction is specifically characterized by being out of battery.
