One of approximately 6,100 Model 1905 pistols manufactured by Colt between 1905 and 1911, with this example manufactured in 1907, being the first pistols chambered for the now legendary .45 Colt Automatic Pistol (ACP) cartridge. The included factory letter confirms the pistol's configuration, including caliber, barrel length, finish, and type of stocks not listed, when sent in a shipment of three pistols to Jensen King Bird Co. of Spokane, Washington, on May 13, 1907. Features fixed rounded blade front and notch rear sights, checkered round spur "stub" hammer with half-cock notch, checkered slide catch, exposed extractor, and early brass firing pin. The slide bears the two block, two line patent information and Colt address, with "AUTOMATIC COLT/CALIBRE 45 RIMLESS SMOKELESS" on the right side. With "VP" triangle and "1" sub-inspector proofs on the left of the trigger guard and serial number on the left of the frame. Fitted with a pair of diamond pattern checkered walnut grips. Includes a leather flap holster marked "1305/45" on the back strap.

Very fine, retaining 70% original high polish blue and casehardened finishes with numerous scattered scrapes and dings focused on the left front of the frame and barrel, thinning and grey patina on the grip straps, minor pitting, and otherwise well-defined markings. The grips are very fine with minimal handling wear and otherwise crisp checkering. Holster is very good with cracking on the flap fold.
