If necessity is the mother of invention this gun is it. Has anyone inspected the photos of this thing at all? It appears the trigger guards are also the springs that power the hammers, it has secondary springs to insure the trigger seers lock up when the hammers are pulled back. The hinge for the barrels are held to the bottom of the barrels by screws threaded through the bottoms of the chambers (scary!). There's no photos of the extractors but I'll bet it doesn't have any, that's what the tool in the butt is for. Since the barrels were probably poached from another shotgun I imagine the regulation is probably okay, that is if you have the balls to even shoot the thing! Still as far as whoever built it, I have to give him credit for originality (LOL).
