To determine the year of manufacture for a Colt 1911 .45 based on its serial number, you'll need to reference Colt's serial number charts. The Colt 1911 was produced from 1911 onward, and the serial numbers were assigned sequentially. For example, serial numbers starting with "C" typically indicate a production year in the 1940s. For a precise year, consult a detailed Colt serial number lookup or Colt's records.
