If the function checks do not perform as indicated, what is the next appropriate step?

When function checks on the M9 Service Pistol do not perform as expected, the next appropriate step is to evacuate the weapon to organizational maintenance. This is crucial because any malfunction could indicate a serious issue that needs to be addressed by qualified personnel. Organizational maintenance is specifically equipped and trained to diagnose and resolve potential mechanical failures, ensuring that the firearm is safe and operational before returning it to service.

In this situation, maintaining safety is paramount, and directly involving maintenance helps to prevent potential accidents or further damage to the weapon. The other actions like reporting to a higher authority or emptying the magazine might not address the underlying problem and could lead to unnecessary risks. Continuing with normal operation would be particularly dangerous, as it ignores the malfunction that could compromise safety and effectiveness.
