A stun-gun dart has a bullet shaped body that defines both a cavity and a front aperture. A spear is disposed within the cavity, is aligned to the aperture and has a sharp, barbed front tip and a rear mass-piece that is wider than the aperture, to prevent the spear from entirely passing through the aperture. Also, a spring has a first end attached to the body and a second end attached to the rear mass-piece of the spear, and is properly tensioned to entirely retain the spear within cavity until the dart undergoes rapid deceleration. But when the dart, after being fired into air and hitting a target, undergoes rapid deceleration, the spring permits the tip of the spear to protrude from the aperture to engage with and barb to flesh.

The invention claimed is: 1. A stun-gun dart, comprising:(a) a bullet shaped body, defining a cavity and a front aperture;(b) a spear disposed within said cavity, aligned to said aperture, having a sharp, barbed front tip and a rear mass-piece that is wider than said aperture, so as to prevent said spear from entirely passing through said aperture;(c) a spring having a first end attached to said bullet shaped body and a second end attached to said rear mass-piece of said spear, said spring having proper tension to entirely retain said spear within cavity until said dart undergoes rapid deceleration, but when said dart, after being fired into air and hitting a target, undergoes rapid deceleration, said spear has sufficient momentum, due in part to the mass of said mass piece, that said tip of said spear protrudes from said aperture to engage with and barb to flesh;(d) wherein after said dart has hit flesh and said spear has protruded from said dart and been engaged with and barbed to said flesh and said barb has been subsequently removed from said flesh, said spring automatically retracts said spear fully back into said cavity; and(e) wherein said dart is electrically connected to a source of electricity.
