Electronic defense fills the gap between pepper spray and a firearm. We carry consumer TASER devices - which project darts at range - and contact stun guns, and we are direct about the difference, because the two get confused constantly and the capability gap is enormous.
New Jersey permits adult possession of stun guns and TASER devices under current law, with rules our staff can walk you through at either store. For a household defense plan, these pair sensibly with a spray as layers, not replacements.
