In what year was the M1911 pistol designed?

The M1911 pistol was designed in 1911 because it was the result of a collaboration between prolific firearms designer John Browning and the US Army Ordnance Department. Seeking a replacement for the previous sidearm, the US Army wanted a new semi-automatic handgun that offered reliability, stopping power, and ease of use. After extensive testing and modifications, Browning's design was chosen and adopted as the official sidearm of the US military. The year 1911 is significant as it marks the official designation and introduction of this iconic firearm, which went on to serve as a standard issue sidearm for over seven decades.
