Glock30.jpg

The gun is a mechanical weapon which uses expanding gas to fire a bullet, dart or other projectile through a tube (its shaft). Guns are primarily defensive weapons.

The four main types of modern firearms today are bolt-operated, pump action, semi-automatic, and automatic weapons. In a bolt-action weapon, each new round must be loaded manually, by moving the breech to eject the empty casing. In pump action guns (usually shotguns) a new round must be manually loaded by pulling back on pump of the gun, located underneath the barrel.

In semi-automatic weapons, each pull of the trigger fires a bullet, each shot ejecting spent brass and loading new ammunition until the magazine is depleted. In fully automatic weapons, bullets will be fired as long as the trigger is depressed. Fully automatic fire will cause the gun to heat up very quickly, which can become dangerous as it can burn exposed flesh and because rounds may "cook off" or fire unexpectedly due to the chamber becoming hot enough to ignite the propellant.

History

Gunpowder was invented in China around the 800s AD. The Chinese recognized the substance's potential for warfare and used gunpowder in rockets and bombs. In the twelfth century, firearms were invented there, and this technology, though inefficient and costly at the time, quickly spread to the Islamic World and Europe. Guns at this time were very inaccurate and not particularly powerful (a full suit of armor could easily repel gunfire) and thus played only a minor role in European warfare until the mid-fifteenth century.

The gun soon became a central part of the Western arsenal, and saw extensive use in both European battlefields and the Colonization of the Americas, where guns were used to subdue native populations.

The eighteenth, nineteenth, and twentieth centuries saw major changes in the design of guns that allowed for better range, accuracy, and firing rate, such as rifling.

Gun control

Adolf Hitler was a proponent of gun control

Gun control consists of limitations on the ownership of firearms, and by extension restricts the fundamental right of self-defense.

Conservatives usually emphasize the individual the right to self-defense through the use of guns. Liberals more often oppose this individual right, and tend to dislike even guards or police carrying guns.

Guns are shown to be highly effective at deterring crime and protecting the gun owner. Police officers often use guns to enforce the law, except in some countries where the police are not armed. In the Republic of Ireland, the Garda Síochána has since its foundation held that uniformed officers do not carry guns - "The Garda Síochána will succeed not by force of arms or numbers, but on their moral authority as servants of the people", as the first Commissioner said[1]. The current Commissioner of the Gardaí has stated that "we do not live in a 'gun culture'", despite a recent rash of armed crime. In Iceland, there are no armed forces, including the Police, and all Police only carry a baton on duty.[2] In addition, the regular Police forces of the UK[3] and the Police Force of New Zealand do not carry firearms while on normal patrol, or in the latter case describe themselves as "generally unarmed"[4]. However, each of these Police forces also has highly trained specialist teams of armed Police, who are brought into play at time of need.

Studies have repeatedly shown that law-abiding citizens carrying guns are an effective deterrent against crime[5][6][7]. Further comparison between different states by John Lott indicates that states that have more conservative gun laws have lower crime rates, violent crime rates, and firearms homicides than states with more liberal gun laws.

Guns are also a defense against a tyrannical government. The 20th century has proved repeatedly that a well-armed and dedicated guerrilla army can defeat even the strongest occupying army using only small arms. Thus, guns potentially act as a deterrent against a tyrannical government.

Science Fiction

Science fiction, such as Star Trek, has postulated many different types of directed energy weapons. These are guns that fire beams, waves, or packets of energy. Some energy guns can be set to stun, not to wound or kill. Most firearms legislation would not classify these as firearms, so their ownership would be unrestricted.

Miniguns

One unusual type of gun is a minigun. Despite what you would think from the name, a minigun is the biggest of all small-arms. A minigun has multiple barrels which are driven by a loud electric motor. This allows it to have a very high rate of fire, and is a major difference from the systems of operation described at the top of the article.

Miniguns are commonly seen in the movies, notable examples being Terminator 2 and Predator, where miniguns can be seen exploding multiple police cars or cutting down whole areas of forest. In reality miniguns probably cannot actually cut down trees, and standard 7.62mm ball ammunition would not cause a car to explode, although a tracer round might if it hit the gas tank.
