The Colt Model 1903 Pocket Hammerless is a .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 a variant introduced five years later in .380 ACP caliber. Despite the title "hammerless", the Model 1903 does have a hammer. The hammer is covered and hidden from view under the rear of the slide, this allows the pistol to be carried in and withdrawn from a pocket quickly and smoothly without snagging.
