You need to revise your history. The 10mm was the brainchild of Jeff Cooper working with others. It first came out in 1983, and originally in the Dornus and Dixon Bren 10. The company failed, primarily due to inability to deliver magazines, or functional pistols.
Colt picked it up in 1986, and released the Delta Elite. It was poorly adapted to the Norma ammunition which was loaded to far above current SAAMI specifications (Norma uses C.I.P. standards].
The FBI adopted the S&W 1076 a shortened d/an only version of the 1006 in 1990, using reduced power ammunition. (180gr bullet @1,050fps vs 1,350fps).
I was an early adopter and a huge supporter of the 10mm. I had a 1006 that was a brute of a gun and well suited to the original 10mm Norma ammo. A Glock G20 10mm wouldn’t stand the Norma ammo, nor my duplicate handloads. I sold both as I was actively shooting NRA PPC and needed suitably accurate pistols.
