A toy gun capable of firing a projectile and simultaneously or near simultaneously, emitting smoke from the muzzle of a barrel of the gun after the projectile has been discharged from the muzzle. The toy gun has first and second rechargeable air pumps, with the first air pump automatically discharging stored air into a breech part of the barrel in order to propel a loaded projectile from the barrel, and the second air pump expelling stored air through a flow restriction device which serves as a pressure switch for actuating a smoke generator located adjacent to the muzzle. The second air pump also provides a low air flow rate through the smoke generator to expel smoke therefrom. The second air pump expels stored air much more slowly than the first air pump. The first and second air pumps are simultaneously triggered to release stored air by a user.
