Taser

A  gun is an electroshock weapon designed to incapacitate an individual. This is done so by firing two barbs attached to the ends of two long, thin wires into the target and upon trigger, an electric current passes 50,000 volts of electricity along the wires through the barbs and into the target. This disrupts the nerves and causes the tasered individual to drop to the floor in pain and discomfort.

After ambushing Ashley Magnus and Sylvio Rudd at an eastside warehouse, and trouncing Ashley in a hand-to-hand fight, John Druitt is tasered by Sylvio, causing him to collapse to the concrete floor.
