Actually the Seacamp conversion was a totally different design that used the 1911's original trigger assembly with the actual trigger finger piece cut off.
When the trigger was pulled, it contacted the original trigger bow and operated the sear.
The Double Eagle was a true double action design.
It failed for a number of reasons.
The early guns had a problem with the trigger assembly where under certain circumstances, when the trigger was pulled, the gun would make a "click" but the gun would NOT fire.
After Massood Ayoob wrote about this in an American Handgunner magazine article, the gun's sales took a major hit, and Colt never again advertised in the magazine.
Major working parts and springs were retained ONLY by the grip panels. Remove a grip and spring and small parts went flying.
The appearance of the gun was terrible. Most people thought it was the ugliest gun Colt ever made.
The trigger pull was lousy, and there was nothing that could be done about it.
