What is the meaning of Gun? Concept and Definition of Gun

Gun - its definition and concepts

1. Gun concept

A gun is a short firearm designed to be aimed and fired with one hand, 1 Although you don't have to be necessarily used in that way, and it shoots bullets at short range.
There is also the pneumatic gun, which uses gas or compressed air instead of gas produced by the combustion of gunpowder; This rarely used to carry out attacks against other people because of the low stopping power by relative low output speed with which are fired the low caliber ammunition, on the other hand are mostly used for sport shooting and small game.
Although the first pistols were created in the 17TH century as auxiliary weapons of the Cavalry, used water pistols; It was a method of threat against the fire that was started to be used in the 16th century. the term gun referred to the small knives and daggers that were hidden among clothes. In the first half of the 16th century refer in Spanish the first pistols as small arquebuses. The term pistol was used already in the second half of that century. Beginning of the 17TH, the term gun to refer to the short firearms empuñadas with one hand, was extended.
The word comes from the French pistol, and the Czech pišťala (flute), by way of the ancient weapons of the Hussite wars. Another theory refers to the Italian city Pistoia, where is made the daggers.
Until the 19th century, the gun uses basically the same mechanisms of shooting old rifles and muskets: wheel mechanism in the 16th/17TH, of Flint in the 18th and first part of the 19th and percussion at the appearance of this type of mechanism in the early 19th.
All these guns required manually your ammo reloading after each shot. The ammunition was introduced by the mouth of the Canyon (muzzle-loading gun) and consisted of gunpowder, projectile and WAD of paper (which served as a CAP to keep tablets the previous two in the Canyon and pressed with a gadget called the ramrod). This method of recharging was very slow, and generally, the combatants desenfundaban their sabers or swords after shooting, since the circumstances did not allow to reload the gun again.

Revolver

The first evolution of the gun capable of firing several times prior to reload ammunition was the revolver, also called «rotary gun». Know of a model used by the British army in the 19th century, but Samuel Colt patented the modern revolver in 1835. This system is the ammunition in a kite («drum») detachable rotating with the travel of the trigger back, by placing in this way a new Chamber ('niche') before the striker.
In the breech of the barrel was introduced a portion of black powder (usually DuPont), WAD of paper, ammunition (lead) and retacaba with a lever located under the barrel tube. This procedure was carried out with great care to avoid pressure to inflamed gunpowder advance. From the back of each Chamber of the barrel was placed a fulminant as «first» trigger. Sometimes was covered with grease to prevent the spark of the first shot to set the six chambers, causing the outbreak of the weapon and injury to the shooter. Because of the complex and slow this operation, it was not surprising that Cavalry soldiers carry with them an endowment of preloaded kites, which were removable.
Lack of specialization in the manufacture of the weapons of the time and low quality controls led to a series of accidents in which it was not uncommon to seriously injured the hands at the time of loading and triggering guns.
Commonly, the revolver has six bedrooms, but there are models that have between five and nine.
Semi-automatic gun is called because the mechanism that puts a fresh cartridge into the Chamber after firing is automatic, but as it does single shot whenever the trigger is squeezed, it is not considered automatic weapon.
Semi-automatic pistols have a fixed frame where it is mounted trigger (and its trigger), striker, canon and a moving part, called slide, that fits onto the frame and mounted a spring recuperator and a needle striker, as well as a window of expulsion of the CAP.
The advantage of the semi-automatic on the revolvers is your charger, which allows you to stay more ammo and a recharge, potentially faster. However, the greater complexity of the mechanism increases its cost of manufacturing and makes them more susceptible to breakdowns.
Automatic pistols by semi-automatic mechanism have been erroneously called. A real automatic pistol would be the one that, by holding down the trigger, fired continuously. However, there are guns that have a mechanism to choose between firing in semi-automatic mode or do three shots when the trigger once.

2. Definition of gun

Within the broad group of firearms are guns. It's handguns that can be operated with one hand, which ensures the simplicity to aim and pull the trigger.
The guns have a reduced range: a white that is located at a great distance cannot be achieved with them. These weapons are qualified as semi-automatic since, after firing, the next cartridge is loaded into the breech automatically, though you can only be shot down with each tight of the trigger.
The revolver is a history of the gun, which makes many times used both terms synonymously, especially in colloquial language. However, it is possible to detail several differences between pistols and revolvers: while the first bear ammunition on a charger, revolvers housed them in a drum. Guns can be loaded more bullets than revolvers and its trigger is more sensitive. Revolvers, can on the other hand, using more powerful than guns.
It is important to note that, by its ability to do harm, the guns must be handled responsibly. To buy a gun, it is usually necessary to register with any agency of the State and demonstrate skill in handling the weapon. It is also frequent, in order have the enabling of carrying or transferred from a gun, the person concerned must undergo a psychological expertise that confirm that it is an individual in a position to take responsibility.
