Colt Walker Colt Walker The Colt Walker, sometimes known as the Walker Colt, was a single-action revolver with a revolving cylinder holding six charges of black powder behind six bullets (typically .44 caliber lead balls). It was designed in 1846 as a collaboration between Captain Samuel Hamilton Walker and American firearms inventor Samuel Colt. The 1847 Colt Walker was the largest and most powerful black powder repeating handgun ever made. It was created in the mid-1840s in a collaboration between Texas Ranger Captain Samuel Hamilton Walker (1817–47) and American firearms inventor Samuel Colt (1814–62), building upon the earlier Colt Paterson design.

Colt Open Top Pocket Model Revolver White patent for metallic cartridges firearms manufacture expired (c. 1870) the Colt's Patent Fire Arms Manufacturing Company started working on its own metallic cartridge revolvers (Colt had previously been manufacturing the so-called Richards-Mason conversions). Thus, Colt introduced its first rear-loaders in 1871: the Colt House/Cloverleaf and the Colt Open Top Pocket Model Revolver. In the 1870s the firearms market was awash with cheaply made knockoffs of the .22 caliber Smith & Wesson Model One which sold for about $2. Colt's president Richard Jarvis decided it would not compete directly with the knockoffs; that its .22 would be of Colt quality.
