A pistol is a personal shotgun (carried and operated by one person) with a short barrel that is easy to hide in the human clothing that carries it. It has one grip for stabilization during firing and is effective for ranges of only a few dozen meters.
The gun is smaller than other personal guns, such as a assault rifle and submachine gun, and the user holds it only at one point (as opposed to the five assault rifle handles - grip handle, cartridge, hand grip, shoulder socket of the butt and cheek surface). Hence the advantages and disadvantages of the gun on other personal weapons: it is more difficult to stabilize it when shooting, and therefore its effective range is shorter (tens of meters instead of hundreds of meters), but it is easier to carry and easier to hide in the human clothing that carries it. 

Unlike other firearms, many guns have a mechanism that allows the first bullet to be fired without arming the gun, provided that the ball is placed in a timely manner. This mechanism is activated by pulling the trigger more force than is necessary for a normal pressure on the trigger and is called a "double action" since the trigger squeezes the hammer back and releases it for firing. Another difference between most of the other weapons and the gun is that the hammer hitting the probe is external and exposed to many of the pistols.

Like the assault rifles and the submachine gun, the mechanism of operation of the gun is a closed belt. This is reflected in a lower fire rate than that of the submachine gun but as high as the assault rifle. The rate of fire of a submachine gun is not required for a gun because its quantity of ammunition is more limited and is not convenient for rapid firing.

In gun training, as opposed to shooting exercises with other personal weapons, emphasis is placed on quick-pull training - training for quick entry into combat mode and rapid target damage. The need to quickly hit the target, as well as the fact that the distance between the targets is short, causes the target to be aimed at the target with a gun, in contrast to the assault rifles and machine guns, in which the direction is sometimes blurred, sometimes between intentions and sometimes when the bullets are fired. They do not fire bundles and therefore do not aim at a harming method.

History of Pistol

The gun originated in the 16th century. The guns were invented parallel to the cannons, as a result of the development of gunpowder. The first guns were actually "hand guns" - the person carrying the gun would compel the gunpowder, put the bullet and finally shoot.

During the 19th century, with the appearance of the modern hammer and pestle system, it gradually replaced the flint. At first the round guns appeared, with a drum that usually contained five or six bullets. When the hammer is hammered back, the drum turns and brings the nearby ball against the pipe leading to the barrel, ready to fire. Over time, guns with cartridges were also developed, which were usually placed in the butt of the gun and contained many more bullets.
Flintlock appeared with flint guns, which gained great popularity during their time and pushed the sword as the main weapon of the duel. The need for more than one shot resulted in the invention of a number of "strange" pistols with a number of nests or a knife attached as a bayonet or an ax blade.
