It's similar, but not quite - the DOE one was an official Colt product, the Model 633, and it was in 9mm, while this was made by a small gunsmithing company (or maybe even just the one guy, Timothy F. La France, I can't find much information on how big the actual company was). I assume it was probably inspired by the Colt one, but I'm not sure if the dates line up.
this is the same model that the Department of Energy security force uses, right?
