Agree with Mykeal has said with the exception that Colt Blackpowder Arms Co. produces the Signature Series Colts under a license from Colt that are erroneously called 3rd Generation Colts. They are not considered to be Colts and are not recognized as such by Colt
I have a Colt Signature third model dragoon. One that was assembled in NY. I talked to the factory after I sent the revolver back. From the factory, it was out of time.
The major parts are made by Uberti. Colt is able to stamp "made in America" due to content laws. I don't know what they did to the Uberti parts, but they found a way to do enough work on the Uberti parts, under the content laws, to label the revolvers as "American Made".
Content laws have been watered down to the point that if an American sees it, it gets the "Made in America" label.
