The Colt Single Action Army which is also known as the Single Action Army, SAA, Model P, Peacemaker, M1873, and Colt .45 is a single-action revolver with a revolving cylinder holding six metallic cartridges. It was designed for the U.S. government service revolver trials of 1872 by Colt's Patent Firearms Manufacturing Company – today's Colt's Manufacturing Company – and was adopted as the standard military service revolver until 1892. The Colt SAA has been offered in over 30 different calibers and various barrel lengths. Its overall appearance has remained consistent since 1873. Colt has discontinued its production twice, but brought it back due to popular demand. The revolver was popular with ranchers, lawmen, and outlaws alike, but as of the early 21st century, models are mostly bought by collectors and re-enactors. Its design has influenced the production of numerous other models from other companies. The Colt SAA revolver is a famous piece of Americana, known as "The Gun That Won the West". ==History== Bound by the Rollin White patent () and not wanting to pay a royalty fee to Smith & Wesson, Colt could not begin development of bored-through revolver cylinders for metallic cartridge use until April 4, 1869. For the design, Colt turned to two of its best engineers: William Mason and Charles Brinckerhoff Richards who had developed a number of revolvers and black powder conversions for the company. Their effort was designed for the United States government service revolver trials of 1872 by Colt's Patent Firearms Manufacturing Company and adopted as the standard military service revolver. Production began in 1873 with the Single Action Army model 1873,〔(【引用サイトリンク】 title= History: The Colt Legend )〕 also referred to as the "New Model Army Metallic Cartridge Revolving Pistol". The very first production Single Action Army, serial number 1, thought lost for many years after its production, was found in a barn in Nashua, New Hampshire in the early 1900s.〔 It was chambered in .45 Colt, a centerfire design containing charges of up to of fine-grained black powder and a blunt roundnosed bullet. Relative to period cartridges and most later handgun rounds, it was quite powerful in its full loading.〔 The Colt Single Action Army revolver, along with the 1870 and 1875 Smith & Wesson Model 3 "Schofield" revolver, replaced the Colt 1860 Army Percussion revolver. The Colt quickly gained favor over the S&W and remained the primary US military sidearm until 1892 when it was replaced by the .38 Long Colt caliber Colt Model 1892, a double-action revolver with swing-out cylinder. By the end of 1874, serial no. 16,000 was reached; 12,500 Colt Single Action Army revolvers chambered for the .45 Colt cartridge had entered service and the remaining revolvers were sold in the civilian market. The Colt .45 is a famous piece of American history, known as "The Gun That Won the West". 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「Colt Single Action Army」の詳細全文を読む スポンサード リンク
