Just Googled & YouTubed it. Yes, it IS, with the addition of a safety/different latch, the Sharps design.
Fantastic. Plus there is an advantage in barrel length over a similar sized auto or revolver. Because the design has very little mechanics going on aft of the chambers you get a decent barrel in a tight package.
I hope they actually get this one into production soon, because I might step outside my self-imposed No New Guns policy for one.
