A nice configuration but it is really only good for one thing. It’s akin to a “Liberator” 45 ACP gun dropped into France prior to the invasion. Meant to be used for up close dispatching of Nazi guards, etc.
Where government gets antsy about this technology today is that they cannot detect these with metal detectors. One assumes the bullet could be secreted elsewhere as in that Clint Eastwood movie where he was up against assassin John Malkovich.
For my part, I’d rather have something capable of full and sustained power over a lengthy time.
It’s a step in the right direction. We need this technology to develop further though. Eventually, affordable 3D metal printers will come around and then they’ll truly have something to worry about.
If people can make a printed “Liberator “ pistol people can make what is called a “WELROD pistol” & that really scares the politicians. look up the WELROD pistol on google 8*>.
