Power notwithstanding, Colt Walkers and Dragoons were much too large, heavy, and cumbersome to be carried in a holster on the belt, so eventually, Colt went the complete opposite direction and brought out a series of Pocket Pistols, which were five-shot .31 caliber and easily carried concealed on the person. Today these are known mainly as the Baby Dragoon, the Wells Fargo, and the most popular and the highest-selling Colt firearm during the percussion era, the 1849 Pocket Pistol.
