This is a picture of a M-9 Beretta 9mm Pistol. It fires through the use of gasses produced by rapid, confined burning of a propellant such as gunpowder. Pulling the trigger activates a striking device that causes the propellant to explode. Bullets shoot out of a gun when this happens. the first pistol was made in the town of Pistoia in the 1540's.
