At the beginning of World War II, Colt ceased production of the Single Action Army revolver to devote more time to filling orders for the war. During the war Colt manufactured over 629,000 M1911A1 pistols as well as a large number of M1917 water-cooled machineguns. The company had a workforce of 15,000 men and women in three factories and production ran on three shifts, 24 hours a day, and won the Army-Navy rating of "E" for excellence. Colt ranked 99th among United States corporations in the value of World War II military production contracts. However, the company was losing money every year due to mismanagement, an embittered workforce that had been stretched to its limits, and manufacturing methods which were becoming obsolete.
