INCORRECT! You are obviously talking about the OLD series Python and Anaconda, which did have flush muzzle crowns. That is not the case with the NEW revolvers they are making. All of the NEW series Pythons, Anacondas, Cobras, King Cobras, etc do indeed have recessed muzzle crowns. That is a simple fact. I own all of them, so here I am "getting back to you."
Also, the barrels are NOT 2 piece; they DO NOT have shrouds. They are 1 piece barrels. The inset counterbore you showed in your photo is exactly how all the NEW King Cobras and King Cobra Targets are supposed to be; that is not a flaw. Your assumptions are incorrect.
If you look in the corner of the counterbore on the end of your barrel, you will see a radius. That is because that counterbore is milled in there with an endmill and the corner radius is the corner radius on the end mill used to cut that recess. If it was a 2 piece barrel, then that would be a sharp corner because they would be 2 separate parts. They are not. Colt put out a factory tour video in which they clearly say and show that all of their new revolver barrels are machined from a single piece of bar stock. You can see for yourself starting at 4:13 in this video where the Colt representative shows the 1-piece barrel.

All of the CURRENT Colt double action revolvers now come from the factory with recessed muzzle crowns! Lots and lots of guns have recessed muzzle crowns. That is a common feature added to guns to help protect the muzzle crown from getting nicked. In fact, when a custom gunsmith rebarrels a gun, they usually machine a recess on the crown because that is a desirable feature to have and most customers ask for it. Most of the rifles you buy today come with recessed crowns. There are just as many if not more guns with recessed muzzle crowns than flush crowns! Almost all custom 1911s have conical recessed crowns. If you are not familiar with recessed muzzle crowns on guns of all types, you haven't been paying attention or you have limited firearms experience. They have existed on guns of all types for at least 100 years.
First pic is the muzzle end of my NEW series Python.
Second pic is the muzzle of my NEW series Anaconda.
Third pic is the muzzle of my NEW series King Cobra Target .22
Fourth pic is the muzzle of a King Cobra .357 just like yours I copied from GB.
The photo you posted of your King Cobra is EXACTLY the way it is supposed to be from the factory; it is not a defect!
