What is the maximum range of the M9?

The maximum effective range of the M9 pistol is approximately 50 meters, which is significantly less than the options presented. However, if the question concerns the theoretical maximum range of the M9 when considering the bullet's travel without regard for accuracy or effectiveness, it is up to approximately 1800 meters. The ballistics of the 9mm round fired by the M9 allow it to travel this far under ideal conditions.

This range reflects the maximum distance the bullet can travel in a straight line before it descends due to gravity, rather than being indicative of how effective the weapon is at hitting targets or the practical range for accurate shooting. As a result, while 1800 meters is technically accurate as the maximum distance the bullet can reach, it is critical to understand the limitations in terms of effective use in a combat or defensive scenario.

Most operational contexts would caution against relying on such ranges for engagement, emphasizing the importance of engaging targets within a more reasonable distance that allows for accurate shooting and effectiveness.
