First introduced in 1873, the Colt .45 Peacemaker is one of the most iconic firearms in American history. Often romanticized as “the gun that won the West”, this famous revolver played a pivotal role in shaping the American frontier as it was utilized by outlaws, cowboys, lawmen, and civilians alike. The gun’s success firmly established the Colt Manufacturing Company in mainstream culture, leading it to become the forefront of firearms innovation for generations. (This is America’s favorite rifle company.)

To identify the most iconic military firearms built by Colt Firearms, 24/7 Wall St. reviewed a catalog of Colt Firearms from Military Factory, an online database of military vehicles, aircraft, arms, and more. We ordered these firearms chronologically, from the newest to the oldest. We also included supplemental data from the Military Factory regarding the year entered service, type, firing action, caliber, and feed. We excluded firearms that were experimental or prototypes.
