.45 huh?
This video clarifies the common misconception between 'automatic' and 'semi-automatic' pistols, specifically regarding the M1911. Expertly citing historical military designations and technical manuals, the presenter explains that 'automatic' in this context refers to the firearm's auto-loading cycle of operation, not full-auto fire. The M1911 was officially designated 'Pistol, Automatic, Caliber .45' by the U.S. military, a nomenclature that persists in common parlance.
