The Colt Model 1909 was the last military-issue .45 Colt. It would be nearly 100 years before another issue sidearm was specifically marked “USMC,” adding to the appeal of these unique .45s.
In 1909, the Ford Model T had just come to market. The President of the United States was none other than Theodore Roosevelt, finishing his second term. His Great White Fleet had finished its voyage around the globe, announcing to the world that America had arrived as a seapower. The Army Signal Corps had just purchased the world’s first military airplane from the Wright brothers. And Colt was in the process of delivering a new double-action revolver to the military. The .45 Colt-chambered Model 1909 was to replace various .38-cal. revolvers that repeatedly struggled to stop fanatical attackers in the then-ongoing Philippine Insurrection. The Army would receive approximately 20,000 1909s before the iconic U.S. Model of 1911 pistol was adopted. The Marine Corps specified a few changes to the gun for its order of 1,400.
It is a well-established part of shooting lore that the U.S. military went back to the .45 Colt after dissatisfaction with the stopping power of its .38 revolvers in the early 1900s. More studied enthusiasts could probably tell you that the handgun was a double-action Colt revolver in .45 Colt. Beyond those details, things generally get fuzzy.
