The Colt Model 1903 Pocket Hammerless is a 9-shot, .32 ACP caliber, self-loading, semi-automatic pistol designed by John Browning and built by Colt Patent Firearms Manufacturing Company of Hartford, Connecticut. The Colt Model 1908 Pocket Hammerless is an 8-shot, .380 ACP caliber variant introduced five years later. Despite the title "hammerless", the Model 1903 does have a hammer. It is covered and hidden from view under the rear of the slide. This allows the pistol to be carried in, and withdrawn from a pocket quickly and smoothly without snagging.
