M9 9mm semiautomatic pistol

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 discharges. 

  • 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 inserted. 

  • 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.

To Load:

  • 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 heard.

  • 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 loaded, however, and should not be pointed at anything you do not intend to shoot..

To Fire:

  • 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 round.

  • 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 open position.
