Designed by John Browning, the M1911 is the best-known of his designs to use the short recoil principle in its basic design. The pistol was widely copied, and this operating system rose to become the preeminent type of the 20th century and of nearly all modern centerfire pistols. It is popular with civilian shooters in competitive events such as USPSA, IDPA,International Practical Shooting Confederation, and Bullseye shooting. Compact variants are popular civilian concealed carryweapons, because of the design's inherent slim width and the power of the .45 ACP cartridge.[5]
