What it is
The 1911 is a single-action, recoil-operated semi-automatic pistol design. “1911” can refer to the military pattern, Colt models, or a wide field of later manufacturers and configurations.
Development and history
The design was adopted by the United States military in the early twentieth century and remained influential through service, competition, custom work, and civilian ownership. Colt remains an important reference point, but not every 1911 is a Colt.
Why it matters
The 1911 illustrates how a military pattern becomes a platform: the same broad name can cover different makers, materials, dimensions, safeties, and chamberings. A useful database must name the maker and variant.
Safety and owner resources
Use the manual from the actual manufacturer and model. Do not infer controls or dimensions from a generic 1911 label.
