Editing M1911 pistol (section)

{{Main|Joint Service Small Arms Program}}
At the end of hostilities the government cancelled all contracts for further production and made use of existing stocks of weapons to equip personnel. Many of these weapons had seen service use, and had to be rebuilt and refinished prior to being issued. 

From the mid-1920s to the mid-1950s thousands of 1911s and 1911A1s were refurbished at U.S. arsenals and service depots. These rebuilds consisted of anything from minor inspections to major overhauls. 

Pistols that were refurbished at government arsenals will usually be marked on the frame/receiver with the arsenal's initials, such as RIA for Rock Island Armory or SA for Springfield Armory.

By the late 1970s, the M1911A1 was acknowledged to be showing its age. 

Under political pressure from Congress to standardize on a single modern pistol design, the [[United States Air Force|U.S. Air Force]] ran a [[Joint Service Small Arms Program]] to select a new semi-automatic pistol using the [[NATO]]-standard 9mm Parabellum pistol cartridge. 

After trials, the [[Beretta 92|Beretta 92S-1]] was chosen. The Army contested this result and subsequently ran its own competition in 1981, the [[Beretta M9|XM9]] trials, eventually leading to the official adoption of the [[Beretta 92#Evolution|Beretta 92F]] on January 14, 1985.<ref name="New York Times Biddle">{{Cite news|url=https://www.nytimes.com/1985/01/15/us/around-the-nation-italian-9-mm-chosen-to-replace-army-s-.45.html|title=AROUND THE NATION; Italian 9-mm.
