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. In 1979, the Joint Service Small Arms Program began searching for a replacement for the venerable M1911, and the 9Г—19mm Parabellum round was selected for compliance with the NATO Standardization Agreement (STANAG).

However, they recognized that the decision was made for the purpose of eliminating the need to buy replacements for worn-out M1911 frames, and to establish a common NATO pistol round to simplify logistics (in the circumstance of war against the Soviet Union in Europe). The service members from the ground combat branches found this arrangement highly contentious. The Department of Defense then decided to synchronize the weapons of all five branches of the U.S. 38 Special revolvers, which were also carried by some criminal investigation/military police organizations, USAF strategic missile ( ICBM) officer crews, and by military flight crew members across all the services when serving in combat zones, or when engaged in nuclear weapons duties. M1911A1 and early M9 with magazines removed Army, Navy, Air Force, and Marine Corps are replacing the M9 with the SIG Sauer M17 and M18. The JCP was renamed Combat Pistol (CP), and the number of pistols to be bought was drastically cut back. 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). Some other pistols have been adopted to a lesser extent, namely the SIG P228 pistol, and other models remain in use in certain niches. military, beating many other contenders, and only narrowly defeating the SIG Sauer P226 for cost reasons. The 92FS won a competition in the 1980s to replace the M1911A1 as the primary sidearm of the U.S. The M9 was adopted by the United States military as their service pistol in 1985. The Beretta M9-officially the Pistol, Semiautomatic, 9mm, M9-is the designation for the Beretta 92FS semi-automatic pistol used by the United States Armed Forces.
