Where there's a will, there's a way. Underestimating the human ability to innovate is always a great way to fail.

I'm not afraid of guns, and I'm not some Luddite, but this shit right here will, at some point, be taken too far by someone with fewer IQ points than needed to keep this concept safe.

This is how those crazy micro-managing laws get written.

I seen some other people bring up the point of how well this could be used in warfare. You strip that handgun down to just the barrel and firing mechanism, reducing weight dramatically. Throw in a FLIR camera with FPV controls from a Humvee possibly even a few miles away, and suddenly you have a (relatively cheap) way to cause damage. Sadly the same could be said for people who want to try this in their backyards, a FPV quadcopter + handgun is not that expensive and I could honestly see this becoming a problem.
