Colt 1900 sight safety intact, 38 caliber, matching number slide, smooth walnut grips, spur hammer. About 25 % blue and the bore is VG. These are the beginning of the Colt semi automatic series, of which millions have been built over 119 years. This is the 1302nd semi auto built by Colt. Many were returned to the factory to have the sight safety altered, but this one, is still in the original configuration.
