The Beretta M9, officially the Pistol, Semiautomatic, 9mm, M9, is a 9×19mm Parabellum pistol adopted by the United States Armed Forces in 1985. It is essentially a military specification Beretta 92FS. The M9 won a competition in the 1980s to replace the M1911A1 as the primary sidearm of the U.S. military, beating many other contenders, and only narrowly defeating the SIG P226 for cost reasons.〔(GAO report, Pistol Procurement, Allegations on Army Selection of Beretta 9mm as DOD Standard Sidearm, June 1986. (page 18) )〕 It officially entered service in 1990.〔(【引用サイトリンク】title=PEO Soldier - Equipment Portfolio )〕 Some other models have been adopted to a lesser extent, namely the M11 pistol, and other models remain in use in certain niches. The M9 was scheduled to be replaced under a United States Army program, the ''Future Handgun System'' (FHS), which was merged with the ''SOF Combat Pistol'' program to create the ''Joint Combat Pistol'' (JCP). The JCP was renamed ''Combat Pistol'' (CP), and the number of pistols to be bought was drastically cut back. ==History== In the 1970s every branch of the U.S. Armed Forces except the U.S. Air Force carried the .45 ACP M1911 pistol. USAF opted to use .38 special revolvers, which were also carried by some criminal investigation/military police organizations, USAF strategic missile (ICBM) officer crews, and by military flight crewmembers across all the services when serving in combat zones or when engaged in nuclear weapons duties. The Department of Defense then decided to synchronize the weapons of all five branches of U.S. forces. The ground combat branches of the services found this decision highly contentious, but was meant to eliminate the need to buy replacements for worn out M1911 frames and to establish a common NATO pistol round to simplify logistics in case of war with the Soviet Union in Europe. In 1979 the Joint Service Small Arms Program began searching for a replacement for the venerable M1911, and the 9×19mm Parabellum round was selected for compliance with the NATO Standardization Agreement (STANAG). In 1980, the Beretta 92S-1 design was chosen over entries from Colt, Smith & Wesson, Walther, the Star M28, and various Fabrique Nationale and Heckler & Koch models. The result, however, was challenged by the US Army, and new tests were done by the Army. In 1984, the trials started again with updated entries from Smith & Wesson, Beretta, SIG Sauer, Heckler & Koch, Walther, Steyr, and Fabrique Nationale. Beretta won this competition, but there was a new trial, the XM10 competition, in 1988. This resulted in two different trials that were more limited but resulted in the Beretta being chosen, albeit with an updated design. Concurrent to the pistol selection process, beginning in 1979 the Bianchi International holster company began its development of a multi-function military holster to be ready for the issuance of a new pistol. This holster, designated the M12, was adopted simultaneously with the adoption of the Beretta 92F in 1985. According to current references, the holster system was designed by John Bianchi and Richard Nichols, and has served the U.S. Armed Forces well for decades. The Beretta 92F survived exposure to temperatures from , being soaked in salt water, being dropped repeatedly on concrete, and being buried in sand, mud and snow. Additionally, the 92F proved a MRBF (mean rounds before failure) of 35,000 rounds. That number is often touted as the equivalent to five or six times the pistol's service life. While this is normally true in European militaries, armed forces of the United States normally subject sidearms to much more extensive use. The Iraq War, which featured frequent urban and room-to-room combat, has required American soldiers to rely more heavily on their pistols.〔Zidock, Alex.
