A toy gun includes a barrel having a bay for receiving a soft projectile loaded within a cartridge. A stock is connected pivotally to the barrel and encases a pneumatic cylinder and piston that is primed upon pivotally opening the stock and barrel. The pneumatic cylinder and piston communicate with the bay when the stock and barrel are closed. A trigger releases the piston to force air into the bay for dispatching the projectile from the cartridge--leaving the cartridge within the bay for ejection upon opening of the stock and barrel.
