What is a 1911 A1 US Army pistol?

It is one of the most iconic firearms ever produced, and it remains popular with collectors and shooters to this day. The gun was designed by legendary firearm designer John Browning, who also designed several other famous guns including the Browning Automatic Rifle (BAR) and M2 machine gun.

The original design for what would become known as the "Model of 1911" was submitted to an army board in trials held between August and September of that year. After further testing, it became clear that some modifications were necessary before the weapon could be adopted for military use. These changes included a shorter trigger reset distance, improved sights, and more durable finishes.

In March of 1911, after these modifications had been made to his original design, John Browning's Model of 1910 handgun – which would later be renamed as simply "the M-1911" – was officially adopted by US military forces under designation "United States Pistol Automatic Caliber .45 Model Of 1911.” The new sidearm quickly proved itself during World War I trench warfare where its stopping power came in handy.
