The M9 is a light weight,
semiautomatic pistol manufactured by Beretta and designed to
replace the M1911A1 .45 caliber pistol and .38 caliber revolvers.
The M9 has redundant
automatic safety features to help prevent unintentional
It can be fired in
either double or single action mode and can be unloaded without
activating the trigger while the safety is in the "on" position.
The M9 pistol has a
15-round magazine, and may be fired without a magazine
This weapon can have
the hammer lowered from the cocked, "ready to fire," position to
the uncocked position without activating the trigger by placing
the thumb safety on the "on" position.
Insert one or more
cartridges into the magazine.
Push the magazine firmly
and fully into the handle of the pistol until a distinct "click" is
With the weapon pointing in
a safe direction, grasp the slide (top of the weapon) and pull it
back as far as it will go.
Release the slide, allowing
it to spring back to its' original position. You have just placed a
round in the firing chamber and cocked the hammer. The weapon is
loaded, ready to fire.
If you are not planning on
firing the weapon immediately, put it on "safe," by keeping it
pointed in a safe direction, and rotating the "ambidextrous safety"
downward. This will automatically lower the hammer to a "half-cock"
position and block the trigger from movement. The weapon remains

Point the loaded weapon at
your intended target.
Flip the "ambidextrous
safety" up (off).
Pull the trigger (long
pull). This will cock the hammer, drop the hammer, and discharge the
After the round is fired,
the slide will recoil backward, and then spring back to its'
original position. This action will eject the empty cartridge case,
bring a new cartridge into the firing chamber, and cock the hammer.
If you fire a second round,
the trigger pull will be much less (short pull), because the hammer
has already been cocked.
If you prefer to fire your
first round with a short pull, you can manually cock the hammer
after rotating the ambidextrous safety to "fire."
When you have fired the
last round from your magazine, the slide will remain in the back or
