Which King Cobra, the older original or the New King Cobra??
The old King Cobra was a medium frame revolver that was the last in the line of the new medium framed transfer bar safety-ignition revolvers began in 1969 with the Mark III series.
The Mark III series was followed by the Mark V series, and the King Cobra was simply a Trooper Mark V with a different profile barrel and was first offered in stainless steel.
The Python was also a medium framed revolver, first made in 1908 as the Army Special.
The frame is a totally different design from the later Mark III-King Cobra, and has a completely different action.
About the only thing the King Cobra and the Python had in common was that both were medium size frames and were made by Colt.
No parts or grips interchange between the two.
The new King Cobra is a small frame revolver.
This is the same size frame and cylinder as the older Colt "D" frames like the Detective Special, Cobra, Agent, and Diamondback.
However, while the frames and cylinders are the same size as the older "D" frame models, the new Cobra and King Cobra are totally different actions.
Again, these new models have transfer bar ignition-safety actions that are totally different then the older "D" frame models.
In addition, unlike either the original King Cobra or the Python, the new King Cobra is made of MIM, (Metal Injection Molding) technology, and doesn't have a forged steel frame and barrel.
The only modern Colt large frame revolver was the Anaconda.
