So many people call the .45 Colt, the .45 Long Colt. Others just call it .45 Colt. Some get very put out because there never was a .45 Long Colt, or a .45 Short Colt for that matter. The problem happened way back when the U.S. Army adopted the .45 S&W (.45 Schofield) as their standard revolver cartridge. The 1873 Colt was still the issue side arm though. The .45 S&W would fit in a revolver chambered in .45 Colt ( just like a 38 special fits a 357 magnum). At the time there was a surplus of .45 Colt ammo and the .45 S&W was being issued, so there were .45 Long (Colt) and .45 Short (S&W). Somewhere during all of this, the soldiers starting referring to the .45 Colt as the .45 Long Colt, and people still refer to it as this over 100 years later.
