The MEU(SOC) pistol, officially designated the M45 MEUSOC,〔https://www.fbo.gov/index?s=opportunity&mode=form&tab=core&id=df43476377acd40c0f409faa2ceffc9d&_cview=1&cck=1&au=&ck=〕 is a magazine-fed, recoil-operated, single-action, semiautomatic pistol chambered for the .45 ACP cartridge. It is based on the original M1911 design by John Browning, and has been the standard-issue side arm for the Force Recon Element of the United States Marine Corps' Marine Expeditionary Units since 1985. Its National Stock Number is 1005-01-370-7353.〔 ==History== In the late 1980s, USMC Colonel Robert Young laid out a series of specifications and improvements to make Browning's design ready for 21st century combat, many of which have been included in MEU(SOC) pistol designs.〔 〕 In 2002, an article in ''American Handgunner'' stated that "Marine armorers from the Precision Weapons Section, MCBQ" are making 789 MEU (SOC) 1911's. The revised parts list included barrels, bushings, link pins, sear springs, ejectors, firing pin stops, mainspring housings and mainsprings, all from Nowlin Manufacturing.〔 Slides were ordered from Springfield Armory, with front sight pins, beavertail safeties and recoil spring guides from Ed Brown. Novak was contracted for rear sights, Wilson Combat provided extractors and mag release buttons, while King's Gun Works supplied ambidextrous thumb safeties. A Marine operator may shoot as many as 80,000 rounds from this pistol during a training-cycle and subsequent deployment.〔 However, it is more common for a Marine to return the pistol to the PWS at Quantico for a rebuild after 10,000 rounds have been fired. A rebuild entails discarding almost all of the gun's parts except for the frame, which prior to 2003 was a U.S. Government frame last manufactured in 1945.〔 The frame is inspected and reused if it is still within military specifications.〔〔 There are frames in the USMC inventory that have had as many as 500,000 rounds fired through them.〔 The Officer In Command of the Precision Weapons Shop in 2001, Chief Warrant Officer 5 Ken Davis, stated that the M1911 is "the only pistol that can stand up to this use". However, as the U.S. Marine Corps began its process of hand selecting members from its Force Recon to be submitted to USSOCOM as Marine Corps Special Operations Command, Detachment One (MCSOCOM Det-1), the selection of a .45 ACP M1911A1-based pistol meant roughly 150 units would be needed, more quickly than the PWS could produce them, as PWS were already backlogged with producing DMRs, USMC SAM-Rs, and updating M40A1s to M40A3s, so DET-1 began the search for COTS (commercial off-the-shelf) surrogates to use.〔Rogers, Patrick A.(2003)"Marines New SOCOM Pistol", ''SWAT Magazine'', December 2003, 52-57〕 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「MEU(SOC) pistol」の詳細全文を読む スポンサード リンク
