Geez, fine here's the pitch.
"Nuclear-powered, non-radiation, bio-signature gun! Will last 1000 years from power source. Bio-engineered, so that any proximity of less than one inch, and the gun will fire, for approved users. Customizable, so that up to 500 friends and family can use with inputted bio-signatures, in as little as 2 minutes! And if your power source should ever fail, gun immediately reverts to a standard firearm, with no delay.
NOW, if that tech were available, would you be interested?
No.
