Which manual covers the M9 pistol?

The M9 pistol is covered in FM 3-22.9, which serves as the primary manual for pistol training within the U.S. Army. This manual includes information on weapon system functions, handling, and marksmanship techniques specific to the M9.

It's also important to note that FM 3-22.9 provides detailed guidance on the safety protocols, maintenance, and operational procedures necessary for ensuring that soldiers can effectively and safely employ the weapon. This comprehensive approach ensures that soldiers are well prepared for both training and combat scenarios with the M9 pistol.

Other manuals listed do not pertain specifically to the M9. For example, FM 3-22.65 deals with signal operations, FM 3-25.35 focuses on map reading and land navigation, and FM 3-11.4 relates to joint chemical and biological defense operations. Therefore, the correct selection directly addresses the operational and tactical aspects of using the M9 pistol specifically.
