Please forgive me if there is a thread on this somewhere, or an article but what exactly did the "inventor" of the double tap, actually invent? It's a tilt barrel derringer with double action trigger that cycles through the 2 barrels. This is neither novel, or new.
I know they have 7 patents filed on the design however all I have ever read talks about the new and patented trigger works which makes me ask... is every take on revolver lockwork a new "invention" or just a new design.
Not trying to be grumpy but it seems the gun is really hyped and the invent vs. design thing seems to my mind to just be a symptom of this. I think it has merit and if executed well I might even buy one but it's not some new or earth shattering invention.
