NOTE: For additional information on technical aspects of the M9 pistol, see TM 9-1005-317-10. For additional information on technical aspects of the M11 pistol, see TM 9-1005-325-10.

WARNING

The half-cocked position catches the hammer and prevents it from firing if the hammer is released while manually cocking the weapon. It is not to be used as a safety position. The pistol will fire from the half-cocked position if the trigger is pulled.

1-2. COMPONENTS

The major components of the M9 (Figure 1-3) and M11 (Figure 1-4) pistols are:

a. Slide and Barrel Assembly: Houses the firing pin, striker, and extractor. Cocks the hammer during recoil cycle.

b. Recoil Spring and Recoil Spring Guide: Absorbs recoil and returns the slide assembly to its forward position.

c. Barrel and Locking Block Assembly: Houses cartridge for firing, directs projectile, and locks barrel in position during firing.

d. Receiver: Serves as a support for all the major components. Houses action of the pistol through four major components. Controls functioning of the pistol.

e. Magazine: Holds cartridges in place for stripping and chambering.
