Handgun in the context of "Derringer"

Shot is a collective term for small spheres or pellets, often made of lead. These have been projected from slings since ancient times and were the original projectiles for shotguns and are still fired primarily from shotguns and grenade launchers, while they are less commonly used in riot guns. Shot shells are also available in many handgun calibers in a configuration known as "birdshot", "rat shot", or "snake shot".

Lead shot is also used for a variety of other purposes such as filling cavities with dense material for weight and/or balance. Some versions may be plated with other metals. Lead shot was originally made by pouring molten lead through screens into water, forming what was known as "swan shot", and, later, more economically mass-produced at higher quality using a shot tower. The Bliemeister method has supplanted the shot tower method since the early 1960s.

Shooting sports are a group of competitive and recreational sporting activities which focus on shooting accuracy, precision and speed. Shooting is the art of using ranged weapons, mainly firearms and airguns, such as handguns, rifles and shotguns, and also bows/crossbows.

Shooting sports can be categorized by equipment, shooting distance, targets, time limits and the degree of athleticism involved. Shooting sports may involve both team and individual competitions, and team performance is usually assessed by summing the scores of the individual team members. Due to the noise and high impact energy of the projectiles, which can be lethal, shooting sports are typically conducted at either designated permanent shooting ranges or temporary shooting fields in areas away from human settlements.

A pistol is a type of handgun, characterized by a barrel with an integral chamber. The word "pistol" derives from the Middle French pistolet (c. 1550), meaning a small gun or knife, and first appeared in the English language c. 1570 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 housing multiple chambers) and the pocket-sized derringers (which are often 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 lack of a buttstock) and strict laws and regulations governing their manufacture and sale (where they are regarded as submachine gun equivalents).

The hand cannon (simplified Chinese: 火铳; traditional Chinese: 火銃; pinyin: huǒchòng or 手铳; 手銃; shǒuchòng), also known as the gonne or handgonne, is the first true firearm and the successor of the fire lance. It is the oldest type of small arms, as well as the most mechanically simple form of metal barrel firearms. Unlike matchlock firearms it requires direct manual external ignition through a touch hole without any form of firing mechanism. It may also be considered a forerunner of the handgun. The hand cannon was widely used in China from the 13th century onward and later throughout Eurasia in the 14th century. In 15th century Europe, the hand cannon evolved to become the matchlock arquebus, which became the first firearm to have a trigger.

An air gun or airgun is a gun that uses compressed air or other pressurized gases to fire projectiles, reminiscent of the principle behind the ancient blowgun. This is in contrast to a firearm, which shoots projectiles using pressure generated via combustion of a chemical propellant, most often black powder in antique firearms and smokeless powder in modern firearms.

Air guns come in both long gun (air rifle) and handgun (air pistol) forms. Both types typically propel metallic projectiles that are either diabolo-shaped pellets or spherical shots called BBs, although in recent years Minié ball-shaped cylindro-conoidal projectiles called slugs are gaining more popularity. Certain types of air guns (usually air rifles) may also launch fin-stabilized projectile such as darts (e.g., tranquilizer guns) or hollow-shaft arrows (so-called "airbows").

A sidearm is an individual-served weapon that is kept at one's side and can be rapidly accessed if needed. A sidearm may be carried alone or as an ancillary weapon to a more frequently-used primary weapon. The term historically referred to swords, daggers, and similar small weapons kept at one's side in a sheath, and in modern combat dominated by guns, sidearms are often defined as handguns that are similarly kept in a holster.

A sidearm is typically required equipment for military officers and may be carried by law enforcement personnel. Usually, uniformed personnel of these services wear their weapons openly, while plainclothes personnel have their sidearms concealed under their clothes.

An armored vehicle (also known as an armored cash transport car, security van, or armored truck) is an armored van or truck used to transport valuables, such as large quantities of money or other valuables, especially for banks or retail companies. The armored car is typically a multifunctional vehicle designed to protect and ensure the wellbeing of the transported contents and guards. Typically customized on a basic van or truck chassis, they feature bullet-resistant glass, armor plating, and reinforced shells and cabs. Armored cars are designed to resist attempts at robbery and hijacking, being able to withstand bullets from most handguns and rifles, as well as extreme degrees of heat, explosives, and collisions.

Snake shot, rat shot, or dust shot, more formally known as shotshell (a name shared with the shotgun shell) or canister shot, refers to handgun and rifle cartridges loaded with lead shot canisters instead of bullets, intended for pest control (essentially small arms canister shot). The main targets for such ammunition are snakes, rodents, birds, and other pests at very close range.

The most common snake shot cartridge is .22 Long Rifle loaded with No. 12 shot. From a standard rifle these can produce effective patterns only to a distance of about 3 m (9.8 ft), but in a smoothbore shotgun (or garden gun) that can extend as far as 15 m (49 ft).
