Vis (Polish designation "pistolet wz.
 35 Vis", German designation "9 mm Pistole 35(p)", or simply the Radom in English sources) is a 9×19mm caliber, single-action, semi-automatic pistol.
 Inspired by American firearms inventor John Browning's 9mm "Browning GP" pistol design which was completed after Browning's death by designers at Fabrique Nationale in Herstal Belgium, this Polish gun began production at the Fabryka Broni (Arms Factory) in Radom in 1935, and was adopted as the standard handgun of the Polish Army the following year.
 The pistol was valued by the Germans, and towards the end of the war issued to the German paratroopers.
 As a pistol largely based on the Colt 1911 and using 9 mm rounds, it is highly prized among collectors of firearms.
The Salvator-Dormus pistol holds the earliest patent for a semi-automatic pistol.
 It was patented on 11 July 1891 by Archduke Karl Salvator of Austria and Count George von Dormus.
 As the first of its kind, it was designed without the benefit of experience with earlier models.
 Various modifications were made with approximately twenty prototypes before thirty pistols of a workable design were submitted for Austrian military trials in 1896.
 This 8mm blowback pistol loaded through the top and had a hinged magazine door on the butt.
 The pistol had a separate bolt release and safety.
 The production delay between patent and military trials allowed comparison with other self-loading pistols, and the Salvator Dormus was considered inferior to its competition.
 The designers abandoned this project; and the few surviving pistols are true rarities.
The Schönberger-Laumann 1892 is regarded by some sources as the first semi-automatic pistol; although its 25 November 1891 Austrian patent was preceded by the 11 July 1891 patent awarded for the Salvator Dormus pistol.
 Austrian inventor Joseph Laumann modified his 8mm repeating pistol in 1892 to use a blowback actuated self-loading mechanism.
 The pistol retained the original large cocking lever attached to the underside of the frame in front of the trigger.
 Approximately thirty-five were manufactured before production ceased when the Austrian military rejected the design in 1896.
A semi-automatic pistol is a type of pistol that is semiautomatic, 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.
The 8×50mmR Lebel (8mm Lebel) (designated as the 8 × 51 R Lebel by the C.I.P.) rifle cartridge was the first smokeless powder cartridge to be made and adopted by any country.
 It was introduced by France in 1886.
 Formed by necking down the 11mm Gras black powder cartridge, the smokeless 8 mm Lebel cartridge started a revolution in military rifle ammunition.
 Standard 8mm Lebel military ammunition was also the first rifle ammunition to feature a spitzer boat tail bullet (Balle D), which was adopted in 1898.
 The long-range ballistic performance of the 8mm Lebel bullet itself was exceptional.
 For use in the magazine tube-fed early Lebel rifle, the 8mm case was designed to protect against accidental percussion inside the tube magazine by a circular groove around the primer cup which caught the tip of the following pointed bullet.
 However, the shape of its rimmed bottle-necked case, having been designed for the Lebel rifle's tube magazine, also precluded truly efficient vertical stacking inside a vertical magazine.
 The bolt thrust of the 8mm Lebel is relatively high compared to many other service rounds used in the early 20th century.
 Although it was once revolutionary, the 8mm Lebel was declared obsolete after World War I and was soon after replaced with the 7.5×54mm French round.
8 mm film is a motion picture film format in which the film strip is eight millimeters wide.
 It exists in two main versions — the original standard 8 mm film, also known as regular 8 mm or Double 8 mm, and Super 8.
 Although both standard 8 mm and Super 8 are 8 mm wide, Super 8 has a larger image area because of its smaller and more widely spaced perforations.
The 8mm Gasser is a rimmed cartridge used in the Rast-Gasser M1898 revolver and a small number of converted Mauser C96 pistols.
 Its bullet is cylindro-ogival and is of the jacketed type.
The Mauser C96 ("Construktion 96") is a semi-automatic pistol that was originally produced by German arms manufacturer Mauser from 1896 to 1937.
 Unlicensed copies of the gun were also manufactured in Spain and China in the first half of the 20th century.
The 8mm/92 [8 x 27 mm R] is a rimmed cartridge used in the 8mm M1892 revolver and inexpensive handguns manufactured in Belgium and Spain.
 These are usually copies of the "Modele D'ordonnance" revolver itself or of then reputable foreign firearms (Colt Police Positive, Nagant M1895, Rast & Gasser M1898 or S&W Model 10).
The Type 64 pistol () is a semi-automatic pistol, formerly in service with the People's Liberation Army (PLA) but has since been replaced by several other firearms, although it still remains in service with some Chinese police forces.
 The Type 64 pistol was the first firearm to be indigenously developed by the People's Republic of China and was first only issued to high-ranking military officers and officials, but has since been distributed throughout the PLA.
 The Type 64 pistol has subsequently been distributed to various People's Armed Police and civilian police forces.
 The Type 64 pistol should not be confused with the unrelated, but similarly named, Type 64 silent pistol () which can be distinguished from the Type 64 pistol, by its large, integral suppressor.

Question: The 8mm Gasser is sometimes used in what type of semi-automatic pistol that has been converted?
Answer: Mauser C96
