What type of firearm is the M9 pistol classified as?

The M9 pistol is classified as a semi-automatic firearm. This classification means that the pistol uses the energy from firing a round to cycle the action and load the next round into the chamber, allowing for quick successive shots without the need for manually cocking the weapon or ejecting spent cartridges. Each time the trigger is pulled, a single round is fired, and the mechanism automatically readies the next round for firing.

Understanding this classification is crucial because it defines the operational capabilities and handling methods required for effective use. The semi-automatic design contributes to the M9's versatility and effectiveness in various combat scenarios, making it a reliable choice for military personnel.
