The Pistole Parabellum 1908—or Parabellum-Pistole (Pistol Parabellum)〔Fitzsimons, Bernard, ed. ''The Illustrated Encyclopedia of Weapons and Warfare'' (London: Phoebus, 1977), Volume 16, p.1778, "Luger".〕—is a toggle-locked recoil-operated semi-automatic pistol. The design was patented by Georg J. Luger in 1898 and produced by German arms manufacturer ''Deutsche Waffen- und Munitionsfabriken'' (DWM) starting in 1900 with other manufacturers such as W+F Bern, Krieghoff, Simson, Mauser and Vickers;〔http://www.chuckhawks.com/dwm_luger.htm〕 it was an evolution of the 1893 Hugo Borchardt–designed C-93. The first Parabellum pistol was adopted by the Swiss army in May 1900. In German Army service, it was succeeded and partly replaced by the Walther P38 in caliber 9mm Parabellum. The Luger is well known from its use by Germans during World War I and World War II, along with the interwar Weimar Republic and the postwar East German Volkspolizei. Although the P.08 was introduced in 7.65mm Parabellum, it is notable for being the pistol for which the 9×19mm Parabellum (also known as the 9mm Luger) cartridge was developed. Because of its association with Nazi Germany, the pistol has been used in fictional works by many villainous characters over the past several decades. == Design details == One of the first semi-automatic pistols, the Luger was designed to use a toggle-lock action, which uses a jointed arm to lock, as opposed to the slide actions of almost every other semi-automatic pistol. After a round is fired, the barrel and toggle assembly (both locked together at this point) travel rearward due to recoil. After moving roughly rearward, the toggle strikes a cam built into the frame, causing the knee joint to hinge and the toggle and breech assembly to unlock. At this point the barrel impacts the frame and stops its rearward movement, but the toggle assembly continues moving (bending the knee joint) due to momentum, extracting the spent casing from the chamber and ejecting it. The toggle and breech assembly subsequently travel forward under spring tension and the next round from the magazine is loaded into the chamber. The entire sequence occurs in a fraction of a second. This mechanism works well for higher-pressure cartridges, but cartridges loaded to a lower pressure can cause the pistol to malfunction because they do not generate enough recoil to work the action fully. This results in either the breech block not clearing the top cartridge of the magazine, or becoming jammed open on the cartridge's base.〔Hogg, Ian & Weeks, John. "Military Small Arms of the 20th Century". Krause Publications. (2000) ISBN 0-87341-824-7〕 In World War I, as submachine guns were found to be effective in trench warfare, experiments with converting various types of pistols to machine pistols (''Reihenfeuerpistolen'', literally "row-fire pistols" or "consecutive fire pistols") were conducted. Among those the Luger pistol (German Army designation Pistole 08) was examined; however, unlike the Mauser C96, which was later manufactured in a selective-fire version (Schnellfeuer) or ''Reihenfeuerpistolen'', the Luger proved to have an excessive rate of fire in full-automatic mode. The Luger pistol was manufactured to exacting standards and had a long service life. William B. "Bill" Ruger praised the Luger's 145° (55° for Americans) grip angle and duplicated it in his .22 LR pistol. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Luger pistol」の詳細全文を読む スポンサード リンク
