The story of this single action black powder revolver began the same day that the Alamo fell in 1836. That's when Samuel Colt began production of a revolving-cylinder pistol at his Paterson, New Jersey, factory. The 1847 Walker revolver was enthusiastically received by the Rangers of the newly independent Republic of Texas. The reputation earned by the formidable 1847 Walker revolver is what ensured gunmaker Samuel Colt's success.
