A semi-automatic rifle is a type of self-loading rifle whose action will automatically cycle a new round after each shot, but needs the shooter to manually reset the hammer/striker before the next shot can be fired, so only a single round will be discharged each time the trigger is depressed.
John Moses Browning was an American firearms designer who developed many varieties of military and civilian firearms, cartridges, and gun mechanisms – many of which are still in use around the world. He made his first firearm at age 13 in his father's gun shop, and was awarded the first of his 128 firearm patents on October 7, 1879, at the age of 24. He is regarded as one of the most successful firearms designers of the 19th and 20th centuries, and pioneered the development of modern automatic and semi-automatic firearms.
The M1911, also known as the "Government" or "Colt Government", is a single-action, semi-automatic, magazine-fed, recoil-operated pistol chambered for the .45 ACP cartridge. It served as the standard-issue sidearm for the United States Armed Forces from 1911 to 1986. It was widely used in World War I, World War II, the Korean War, and the Vietnam War. The pistol's formal designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original model of 1911 or Automatic Pistol, Caliber .45, M1911A1 for the M1911A1, adopted in 1924. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam War era.
A semi-automatic firearm, also called self-loading firearm or autoloading firearm, is one that not only fires a bullet each time the trigger is pulled, but also performs all steps necessary to prepare it to discharge again—assuming cartridges remain in the firearm's feed device. Typically, this includes extracting and ejecting the spent cartridge case from the firing chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber. To fire again, the trigger is released and re-pressed.
A semi-automatic pistol is a type of pistol that is semi-automatic, meaning it uses the energy of the fired cartridge to cycle the action of the firearm and advance the next available cartridge into position for firing. One cartridge is fired each time the trigger of a semi-automatic pistol is pulled; the pistol's "disconnector" ensures this behavior.
A semi-automatic transmission is an automobile transmission that combines manual transmission and automatic transmission.

The Smith & Wesson Model 39 was a semi-automatic pistol developed for the US Army service pistol trials of 1954. After the Army abandoned its search for a new pistol, the Model 39 went on the civilian market in 1955 and was the first of Smith & Wesson's first generation semi-automatic pistols.
The Model 1902 is a semi-automatic pistol developed by famous American firearms designer John Browning and produced by the Colt's Patent Firearms Manufacturing Company in the early 20th century. The Model 1902 was not a new design, but rather an incremental improvement upon the nearly identical M1900, and would transition from the 1900 into three distinct but related pistols with the same action and cartridge, the 1902 Sporting Model, the 1902 Military model, and the 1903 Pocket Hammer model. The 1902 Sporting model was so similar to the 1900 that it continued the serial number range, while the 1902 Military Model featured a different serial range as did the 1903 Pocket Hammer model. The 1902 Military Model featured a square and lengthened grip frame with an additional round in the magazine, while the 1903 Pocket Hammer featured a shortened barrel and slide but retained the Sporting model grip frame. The Colt M1905 .45 ACP pistol would be derived from the same lineage, also with a different serial number range.
A handgun is a short-barrelled firearm designed to be fired with only one hand. The two most common handgun sub-types in use today are revolvers and semi-automatic pistols.
The Colt Model 1903 Pocket Hammer was a short-recoil, semi-automatic pistol, designed by the American arms designer John Browning. It was a compact version of the Colt Model 1902 Sporting Model pistol derived from the original Colt M1900. The Colt M1902 Sporting Model and 1903 Pocket Hammer model have significant differences to the military inspired Colt 1902 Military Model although they fire the same cartridge. Its design is in no way related to the Colt Model 1903 Pocket Hammerless or the FN Model 1903 pistol.
The Curtis XF13C was a carrier-based fighter aircraft built by Curtiss Aeroplane and Motor Company.
The Savage Model 1907 is a semi-automatic pocket pistol produced by the Savage Arms Company of Utica, New York, from 1907 until 1920 in .32 ACP and from 1913 until 1920 in .380 ACP caliber. Although smaller in size, it is derived from the .45 semi-automatic pistol Savage submitted to the 1906-1911 US Army trials to choose a new semi-automatic sidearm. After several years of testing the Savage pistol was one of two finalists but ultimately lost to the Colt entry, which became famous as the Colt Model 1911. 181 of these .45 ACP pistols were returned to Savage after the testing and sold on the civilian market.
The Handley Page Type D or H.P.4 was a single-seat, single-engined tractor monoplane, the first Handley Page design to fly for more than a few hops. Only one was built.
The Dunne D.7 was one of J. W. Dunne's swept wing tailless aircraft designed to have automatic stability, first flying in 1911. It was a single seat, single engined pusher monoplane developed from the unsuccessful D.6.
The Vickers R.E.P. Type Monoplanes were a series of single-engined monoplane aircraft built by Vickers prior to the outbreak of the First World War. They were developed from a French design for which Vickers had purchased a license, with eight being built.
