The M1911 is the military designation for John M. Browning's .45 caliber automatic pistol. He was employed by Colt Firearms, so the patent gives credit to Colt for this firearm.
The Colt M1911 pistol entered service with the United States Army on March 29th, 1911. The Navy and Marines later adopted the pistol in 1913. Its formal designation was Automatic Pistol, Caliber .45, M1911.
Depends on which .45- 45 Colt, 45 ACP, 45 Magnum, 45-70, and which bullet, and what it is fired from. If you mean the .45 ACP fired by a 1911A1 pistol, velocity varies from 830 FPS up to about 1020 fps. Slow, fat, but gets the job done.
