Abstract: A highly concealable, hand held, single shot weapon of novel design having the appearance and esthetics of a pen like instrument which can be actuated by simultaneously pulling the trigger collar forward and the rear housing rearward in one quick motion. In this position the weapon is in the ready to fire position and can be held in the palm of the head safely, indefinitely. The weapon can either be fired or put into a safe position. To fire, using the thumb and fore finger pull the trigger collar rearward which releases the compressed firing pin assembly to slide forward into the cartridge. To put the weapon into a safe position, turn the trigger collar counter clockwise which sets the control slot of the trigger collar into a position against a set screw that will not allow it to slide rearward.

Abstract: A highly concealable, hand held, single shot weapon of novel design having the appearance and esthetics of a pen like instrument when in a neutral, non-firing mode, which can be actuated by simultaneously pulling the barrel forward and the rear housing rearward in one quick motion, and hinging the rear housing of the device down 90.degree. to the main body and barrel. In this position the weapon is in the ready to fire position and can be held in the palm of the hand safely, indefinately. The weapon can either be fired or returned to a neutral position. To fire, press the trigger inward which releases the compressed firing pin assembly to slide forward into the cartridge. To put the weapon into a safe position, hinge the rear housing of the device upward while pressing the safety button inward and the device will resume a straight pen like appearance.
