A semi-automatic pistol is a type of handgun which uses a single chamber and barrel, with a mechanism powered by the previous shot to load a fresh cartridge into the chamber. One round is fired each time the trigger of a semi-automatic pistol is pulled.

A revolver, which uses multiple chambers and a single barrel, and a derringer, which uses multiple chambers and multiple barrels, also fire one round for trigger pull, but achieve this in different ways and as such are not classified as being semi-automatic.

Additional terms sometimes used as synonyms for a semi-automatic pistol are automatic pistol, self-loading pistol, autopistol, and autoloading pistol.

A semi-automatic pistol harnesses the energy of one shot to reload the chamber for the next, typically via recoil operation, blowback, or gas operation. After a round is fired, the spent casing is ejected and a new round from the magazine is loaded into the chamber, allowing another shot to be fired as soon as the trigger is again pulled.

Most types of semi-automatic pistols rely on a removable magazine to store ammunition before it is fired, usually inserted inside the grip.

After Hiram Maxim introduced his recoil-powered machine gun in 1883, several gunsmiths set out to apply the same principles to handguns, including Maxim. Maxim's designs for smaller firearms using his recoil-powered ideas never went into production. In the 1880s, other designers worked on self-loading designs. The first model to gain any commercial success was the Hugo Borchardt-designed C-93, designed in 1893 and made its public debut in 1894. Borchardt invented the C-93 mechanism, based in large part upon Maxim's toggle-lock principle. The C-93 featured a clever locking mechanism modeled after the human knee joint. in which the mechanical joint is called a knee, or in German Kniegelenk (knee joint).

The C-93 proved mechanically reliable, but was too large and bulky to receive widespread acceptance. Equipped with a screw-on wooden stock, the C-93 served well in small pistol carbines, Borchardt also developed the 7.65mm Borchardt cartridge, around which the C-93 was built.

In 1896, Paul Mauser introduced his first model of the famous Mauser "Broomhandle" semi-automatic pistol, the C96. Using the powerful 7.63mm bottlenecked cartridge originally designed by Borchardt, the Mauser was the first self-loading pistol used extensively in battle, notably the South African War of 1899-1902. These pistols were made in 7.63mm Mauser, along with some models eventually being made in 9mm Parabellum and a small number in .45 ACP for China.

In Belgium in 1896, the first American gun designer to develop self-loading semi-automatic pistols was John Browning, whose models were first manufactured by the Belgian firm of Fabrique Nationale (FN) in Europe and later by Colt in the US. Like Luger's work conducted around the same time in Germany, Browning's first successful design was in 7.65mm, the Browning M1900. Browning also devised a slightly different 7.65mm Browning (.32 Auto) cartridge for his semi-automatic pistol that differed from Luger's 7.65mm Parabellum. Browning also designed .25, .380, and .45 ACP cartridges in addition to .32 ACP for his semi-automatic pistol designs.

Browning also created the locked-breech action now commonly used by nearly all heavy-caliber semi-automatic pistols, and designed the .45 ACP Colt M1911, adopted by the US military in 1911. The Model 1911 is still in active use with some U.S. Special Forces and Marine Corps units. -Wikipedia
