As you often see in the movies, as well as hear from the stories of older comrades, a weapon can fire when it is hit hard or even falls on a hard surface. But do such stories have at least a fraction of the truth in their foundation, or are they all nothing more than an artistic exaggeration of reality? By broadcasting special cases to general practice?
As the saying goes: there is no smoke without fire. However, it is a misconception that a firearm that falls on a hard surface can fire on its own. In any case, in those cases when it comes to modern firearms that have not been worn out by prolonged and not very conscientious use. In addition, there are exceptions to each rule. But first things first.
Ancient weapons, produced back in the 19th century, could indeed fire when dropped, even being completely new. The guns and pistols of that time did not have a developed safety mechanism. With the development of fuses and trigger mechanisms in general, as well as with the advent of automation, spontaneous firing became either impossible or extremely unlikely.
If a modern pistol fired from hitting solid ground, it would spontaneously shoot the entire magazine with cartridges after the very first pull of the trigger. This is because the impact of the recoil is much stronger than the impact even when falling from a height of 2 meters. However, nothing like this happens due to the specifics of the design of the trigger of modern weapons. There are, of course, exceptions to the rule. They concern not only weapons that are in a worn out state, but also hunting rifles, which do not have any safety mechanism.
