A gun handling deterrent device includes a housed, battery-powered electrical assembly for placement within the gun handle, with sub-assemblies to convert the DC to pulsating DC and step up the voltage, and leads to the gun frame and a negative contact member that extends from the handle for positioning adjacent the handle, trigger guard and barrel, such that when the handle, trigger guard or barrel is grasped, the hand contacts both the metal frame and the negative contact member. An actuator switch enables the circuit when the gun is moved from a horizontal position, causing the increased voltage pulsating DC to be delivered to the hand. The shock function is joined or replaced in embodiments where an audio generating device is activated by the actuator switch when the gun is so moved.
