“Smart guns” supposed rely on some sort of RF technology to make sure only the owner can fire the weapon. It seems pretty easy, to me, to create a simple RF jamming device that could render anybody’s firearm inoperable.
a small emp/gun burst of energy could fry the chips, and the gun is useless as a projectile weapon.
You might want to rethink that. In order to guarantee that only the owner can fire his gun the on-board chip must receive an RF signal coded to the owner. If you block all RF signals you will render ALL firearm's in the immediate area inoperable, including the owner's gun. But not a cop's gun.

PS The answer is to defeat the chip in your gun. Be careful as I would expect the designer of the chip to render the gun nonfunctional if the chip was destroyed or removed.
