Beginning in October of 1942, the need for pistols prompted Colt to transfer 6,757 unsold commercial Government Model automatic pistols to their existing military contract. The "Government Model" stamp on the receiver was crudely hammered flat with a peen and restamped "UNITED STATES PROPERTY M1911A1 U.S. ARMY". The Commercial serial numbers were also peened flat including those underneath the firing pin stop plate. These pistols were then re-numbered with the military contract serial number range and then parkerized.
