A model gun with automatic bullet supplying mechanism comprises a pressure accumulating chamber from which a gas leading passage extends, a slider movable along a barrel structure, a pressure receiving portion fixed in the slider at the back of the barrel structure, a movable member provided with first and second inner spaces and arranged at the back of a bullet holding chamber, and a movable valve provided in the first inner space formed in the movable member. The movable valve is operative selectively, during a period in which the gas leading passage is connected with the first and second inner spaces formed in the movable member, to cause gas derived through the gas leading passage from the pressure accumulating chamber to act through the first inner space on a sham bullet in the bullet holding chamber and to shut off gas flow to the bullet holding chamber through the first inner space from the gas leading passage so that the gas derived through the gas leading passage from the pressure accumulating chamber acts through the second inner space on the pressure receiving portion to cause first the pressure receiving portion to move back in company with the slider and then the movable member also to move back for making preparations for supplying the bullet holding chamber with a sham bullet from a magazine.
