Colt Paterson Colt Paterson The Colt Paterson is a revolver. It was the first commercial repeating firearm employing a revolving cylinder with multiple chambers aligned with a single, stationary barrel. Its design was patented by Samuel Colt on February 25, 1836, in the United States, France, and England, and it derived its name from being produced in Paterson, New Jersey. Initially this 5-shot revolver was produced in .28 caliber, with a .36 caliber model following a year later. As originally designed and produced, no loading lever was included with the revolver; a user had to disassemble the revolver partially to re-load it.
Colt Dragoon Revolver had a comparatively shorter cylinder (thus preventing overloading the cylinder) and held up to 50 grains of powder, whereas the Walker had used up to 60 grains of powder. The Dragoon Revolver had a shorter barrel at 7.5 inches (some later revolvers 8 inches) as compared to the barrel on the Walker. A loading lever latch in front of the lever replaced the spring to keep the lever from dropping during recoil, thereby preventing jamming of the revolver. These variations made the Colt Dragoon Revolver 4 pounds two ounces. These changes also reduced the risks of the Colt Dragoon Revolver
