9 millimeter Hi-Power, one of the most famous pistols ever made.]] A pistol or '''handgun''' is usually a small pistols, Revolvers , and Semi-automatic pistols. In the 15th Century the term "pistol" was used for small knives and daggers which could be concealed in a person's clothing. By the 18th Century the term came to be used exclusively to refer to small firearms, or additionally, and more recently, similar devices designed for the aimed discharge of Projectile s by the force of gas pressure stored by means other than chemical (" Air Pistol "). Although all handguns are generally referred to as pistols, some restrict the term "pistol" to single-chamber handguns, such as semi-automatic or single-shot pistols, as opposed to multi-chambered revolvers or multi-barreled Derringer s, and use ''handgun'' for the broader category. The term may be derived from the French ''pistole'' (or ''pistolet''), which, in turn, comes from the Czech ''píšťala'' (flute or pipe, referring to the shape of a Hussite Firearm ). Other suggestions have been made—that it comes from city of Pistoia , Italy , where perhaps a manufacturer was one Camillio Vettelli in the 1540s; or that early pistols were carried by cavalry in holsters hung from the Pommel (or ''pistallo'' in Medieval French ) of a horse's saddle. Pistols are used mainly by police officers, military personnel, or civilians who want a compact Defensive Weapon , or for Shooting Sport s. Some specialized pistols are also used for Hunting . Where available, semi-automatic pistols have become the weapon of choice for civilians, making them widely used outside of the police and military realms where they first became popular over the revolver. For some military usage, the widespread introduction of Body Armor has rendered most pistols ineffective. Personal Defense Weapon s are beginning to replace them in some situations. Hunting pistols often have longer barrels than a typical police or military pistol, and are often equipped with Telescopic Sights . Consequently, they are generally less concealable and some cannot be carried in a Holster . VARIETIES OF PISTOL Nowadays there are three main varieties of pistol: " Automatic " self-loading pistols and Revolver s being by far the two most common types, followed distantly by single-shot hunting or target pistols. In a pistol, the Chamber , in which the cartridge is held for firing, is the rearmost portion of the Barrel . Thus the term "pistol" technically excludes revolvers, although this distinction is often ignored in colloquial usage, where revolvers are commonly referred to as "pistols." Revolvers .]] Revolver s feed Ammunition via the rotation of a cartridge-filled Cylinder , in which each cartridge is contained in its own ignition chamber, and is sequentially brought into alignment with the weapon's barrel by a mechanism linked to the weapon's trigger (double-action) or its hammer (single-action). These nominally cylindrical chambers, usually numbering between five and nine depending on the size of the revolver and the size the cartridge being fired, are bored through the cylinder so that their axes are parallel to the cylinder's axis of rotation; thus, as the cylinder rotates, the chambers revolve about the cylinder's axis. Due to simplicity of construction and operation, revolvers are considered to be more reliable than semi-automatic pistols. Automatic pistols P99 , a Semiautomatic Pistol from late 1990s]] Automatic Pistol s use the recoil or gas energy of each round to cycle the Action , extract the spent Case , and load the next cartridge. While the term ''automatic pistol'' is often applied in colloquial speech or writings to describe what is more accurately a Semi-automatic Pistol , the term ''automatic rifle'' almost always refers to a rifle capable of Fully Automatic fire. Due to the confusion this inconsistent naming convention causes, the term ''semi-automatic'' or ''self loading'' is becoming more common, to prevent confusion with '' Machine Pistol s'', which are pistols capable of fully automatic or Burst Mode fire. Automatic pistols may be hammer, firing pin, or Striker fired. Hunting and target pistols are generally Single Action , while defensive and military handguns designed since World War II are generally Double Action for the first shot, single action for the rest. Some of the latest handguns now offer various trigger modes, including double-action-only or a partially pre-cocked striker or hammer, and some even offer the option of changing the mode of operation with the turn of a switch. Machine pistols A Machine Pistol is generally defined as a firearm designed to be fired with one hand, and capable of fully automatic or Selective Fire . While there are a number of machine pistols such as the GLOCK 18 and later models of the Mauser C96 , these are rare; the light weight and small size of a machine pistol make them difficult to control, making the larger, heavier Submachine Gun a better choice in cases where the small size of a machine pistol is required. Most machine pistols have the ability to attach a shoulder stock (the Heckler & Koch VP70 would only fire single rounds unless the stock was attached) while others, such as the Beretta 93R , add a foreward handgrip. Either of these additions technically create a legal non-pistol under the US National Firearms Act , as pistols are by definition designed to be fired with one hand. The addition of a stock or forward handgrip is considered a design change that creates either a short-barreled rifle or an ''any other weapon'', and therefore such additions are generally only found on legal ''machine guns''. STOPPING POWER See Also: Handgun Effectiveness So-called "stopping power" is the reputed quality in a handgun projectile that forces a violent attacker to cease aggressive momentum when hit. Police and military experience, together with ballistics information, show that such a concept is too simplistic. In reality, the ability to truly stop a violent attacker varies with a number of factors, and is not simply determined by the ballistics characteristics of the particular round under discussion. These additional factors include:
Unfortunately, many people are influenced by television or movies where assailants are not only stopped by a single shot, but are propelled backwards and are immediately taken out of action. In real life, police can cite many examples where an aggressive person has had to be shot 4, 5, or 6 times simply to stop an attack. Conversely, there are also cases where a single small-caliber bullet fired into an extremity has resulted in an attacker fainting, effectively providing single-shot stopping effectiveness. There is no authoritative rule of thumb for estimating the stopping power of a single shot or of multiple shots. For these reasons, police and military personnel (as well as licensed individuals carrying pistols for personal protection) try to maximize as best they can the combination of factors for stopping an assailant effectively. They may:
In the matter of drugs, many people conclude that one may need to go back to the 'Golden Age' of pistols, ones firing a large, slow moving bullet, such as the .45 ACP cartridge. The common pistol used in self defense today is the 9mm pistol, most commonly, the 9x19mm Parrabellum cartridge, which is favoured because may pistols allow the user to carry up to 17 bullets in a standard magazine (These pistols are commonly called 'Wondernines'). But some say the current crop of pistol calibres dont provide the stopping power to defeat a criminal who may be under the influence of drugs such as PCP, Cocaine or Heroin, the latter often is a problem as it reduces the pain felt by the user when shot. This means that there has been a recent comeback in lower capacity, high powered calibres like the .45, but many say this does not provide sufficient magazine capacity to the user, with often the limit being set at 10 rounds in a standard magazine. Thus so, there is an intermediate calibre, the 10mm/.40 was created for this pourpose, to provide police and security agents with sufficiently powered cartridges, but a high enough magazine capacity. ADVANTAGES OF PISTOLS Pistols are smaller, lighter, easier to conceal, faster to bring to bear, and sometimes may have more safety features than other firearms. Generally being an emergency self-defense weapon for use under 25 meters, a handgun bullet neither has the energy of, nor the accuracy of, a bullet shot from a Rifle . PISTOLS AND GUN POLITICS Smaller pistols can also be easily concealed on a person—a trait that is particularly useful to people wishing to carry a handgun for self-protection or for criminals wishing to bear arms. Larger handguns, including many hunting pistols, are often much longer and thus less concealable. For these reasons, handguns are a particular focus of debates on Gun Politics , and in many jurisdictions their ownership is much more heavily regulated than long arms. Gun rights supporters argue that wide legal ownership of pistols, including the right to carry them concealed, actually deters crime rather than increases it. In the United States, 48 states allow some form of Concealed Carry by citizens meeting training or other requirements. 39 of these states, called "shall-issue" states, require issue of a permit if there is no compelling reason not to issue a permit (such as a prior Felony conviction, a Restraining Order , or history of Mental Illness ). The remaining 9 states, called "may-issue" states, may deny a permit for any reason, usually at the discretion of local law enforcement. See the main Gun Politics article or the article on Concealed Carry in particular for more details on this debate.
