A toy water pistol for discharging a volume of liquid temporarily stored under pressure in an expandable bladder. The water pistol includes a reservoir containing liquid which is initially supplied from the reservoir to a charge cavity upon manipulation of a piston. The liquid in the charge cavity is then provided to the bladder, in a pressurized state, through further manipulation of the piston. A trigger is provided for selectively controlling the flow of liquid in an output conduit, which is connected to the bladder, to regulate the liquid expelled from the bladder and output from the water pistol upon user activation of the trigger.
