Handgun
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun, long barreled gun (i.e., carbine, rifle, shotgun, submachine gun, or machine gun) which typically is intended to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols. Before commercial mass production, handguns were often considered a badge of office — comparable to a ceremonial weapon, ceremonial sword – as they had limited utility and were more expensive than the long barreled guns of the era. In 1836, Samuel Colt patented the Colt Paterson, the first practical mass-produced revolver, which was capable of firing five shots repeating firearm, in rapid succession and quickly became a popular personal weapon, giving rise to ...

Semi-automatic Pistol
A semi-automatic pistol (also called a self-loading pistol, autopistol, or autoloading pistol) is a repeating firearm, repeating handgun that automatically ejects and loads cartridge (firearms), cartridges in its chamber (firearms), chamber after every shot fired, but only one round of ammunition is fired each time the Trigger (firearms), trigger is pulled. The pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset manually, unlike the self-cycled firing mechanism in machine pistol, fully automatic pistols. A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt (firearm), bolt, which is usually housed inside the pistol slide, slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer (firearms), hammer/striker is cocked by the slide/bolt movement, and a ...

Revolver
A revolver is a repeating handgun with at least one barrel and a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Because most revolver models hold six cartridges before needing to be reloaded, revolvers are commonly called six shooters or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns. Before firing, cocking the revolver's hammer partially rotates the cylinder, indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-shot firearms that had to be reloaded after each shot. The hammer cocking in nearly all revolvers is manually driven and can be cocked either by the user using the thumb to directly pull back the hammer (as in single-action), or via internal linkage relaying t ...

Firearm
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stabili ...

Pistol
A pistol is a type of handgun, characterised by a gun barrel, barrel with an integral chamber (firearms), chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the English language when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe ''any'' type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder (firearms), cylinder housing multiple chambers) and the pocket gun, pocket-sized derringers (which are often multiple-barrel firearm, multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol. The older single-shot and lever-action pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment. Fully-automatic machine pistols are uncommon in civilian usage because of their generally poor recoil-controllability (due to the l ...

Bullet
A bullet is a kinetic projectile, a component of firearm ammunition that is shot from a gun barrel. They are made of a variety of materials, such as copper, lead, steel, polymer, rubber and even wax; and are made in various shapes and constructions (depending on the intended applications), including specialized functions such as hunting, target shooting, training, and combat. Bullets are often tapered, making them more aerodynamic. Bullet size is expressed by weight and diameter (referred to as "caliber") in both imperial and metric measurement systems. Bullets do not normally contain explosives but strike or damage the intended target by transferring kinetic energy upon impact and penetration. Description The term ''bullet'' is from Early French, originating as the diminutive of the word ''boulle'' (''boullet''), which means "small ball". Bullets are available singly (as in muzzle-loading and cap and ball firearms) but are more often packaged with propellant as a cartri ...

Repeating Firearm
A repeating firearm or repeater is any firearm (either a handgun or long gun) that is designed for multiple, repeated firings before the gun has to be reloaded with new ammunition. Unlike single-shot firearms, which can only hold and fire a single round of ammunition, a repeating firearm can store multiple cartridge (firearms), cartridges inside a magazine (firearms), magazine (as in pistols, rifles, or shotguns), a cylinder (firearms), cylinder (as in revolvers), or a belt (firearms), belt (as in machine guns), and uses a moving action (firearms), action to manipulate each cartridge into and out of the battery position (within the chamber (firearms), chamber and in alignment with the gun barrel#Bore, bore). This allows the weapon to be discharged repeatedly in relatively quick succession, before manually reloading the ammunition is needed. Typically the term "repeaters" refers to the more ubiquitous single-gun barrel, barreled variants. Multiple-barrel firearms such as derringe ...

Rifle
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used in warfare, law enforcement, hunting and shooting sports, target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservatio ...

Shotgun
A shotgun (also known as a scattergun, peppergun, or historically as a fowling piece) is a long gun, long-barreled firearm designed to shoot a straight-walled cartridge (firearms), cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot (pellet), shot, or a single solid projectile called a shotgun slug, slug. Shotguns are most commonly used as smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting Sabot (firearms), sabot slugs (slug barrels) are also available. Shotguns come in a wide variety of calibers and Gauge (firearms), gauges ranging from 5.5 mm (.22 inch) to up to , though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single barreled, double-barreled shotgun, double barreled, or in the form of a combination gun. Like rifles, shotguns also ...

Webster's Dictionary
''Webster's Dictionary'' is any of the US English language dictionaries edited in the early 19th century by Noah Webster (1758–1843), a US lexicographer, as well as numerous related or unrelated dictionaries that have adopted the Webster's name in his honor. "''Webster's''" has since become a genericized trademark in the United States for US English dictionaries, and is widely used in dictionary titles. Merriam-Webster is the corporate heir to Noah Webster's original works, which are in the public domain. Noah Webster's ''American Dictionary of the English Language'' Noah Webster (1758–1843), the author of the readers and spelling books which dominated the American market at the time, spent decades of research in compiling his dictionaries. His first dictionary, ''A Compendious Dictionary of the English Language'', appeared in 1806. In it, he popularized features which would become a hallmark of American English spelling (''center'' rather than ''centre'', ''honor'' rat ...

Anglophone Countries
The English-speaking world comprises the 88 countries and territories in which English is an official, administrative, or cultural language. In the early 2000s, between one and two billion people spoke English, making it the largest language by number of speakers, the third largest language by number of native speakers and the most widespread language geographically. The countries in which English is the native language of most people are sometimes termed the Anglosphere. Speakers of English are called Anglophones. Early Medieval England was the birthplace of the English language; the modern form of the language has been spread around the world since the 17th century, first by the worldwide influence of England and later the United Kingdom, and then by that of the United States. Through all types of printed and electronic media of these countries, English has become the leading language of international discourse and the lingua franca in many regions and professional fiel ...
