Colt Autoloading Pistol Identification Guide

This is one of a series of identification guides for the small arms produced by Colt. Colt purchased the Browning Autoloading Pistol Patent in 1897. The first Colt Autoloading Pistol was produced in 1900. Development and refinements were incorporated into the design, culminating in the M1911 .45 acp being accepted as the standard U.S. sidearm. To the best of our knowledge, all the examples shown are original pre-1945 manufacture. If anyone has questions or suggestions, please contact [email protected].
