A free standing cordless gun for dispensing liquid glue that includes a housing that is pistol-shaped and dispensing apparatus that is contained in the housing for dispensing the liquid glue. The liquid glue is dispensed through a muzzle bore in a barrel of the housing, by first depressing a trigger of the dispensing apparatus, which causes a reversible motor of the dispensing apparatus to be powered by a rechargeable battery and rotate in one direction, which causes a shaft of the reversible motor to rotate in the one direction, which causes a first beveled gear of the dispensing apparatus to rotate in the one direction, which causes a second beveled gear of the dispensing apparatus to rotate in the one direction, which causes an internally threaded tube of the dispensing apparatus to rotate in the one direction, in place, in a pair of roller bearing disks of the dispensing apparatus, which causes an externally threaded ram rod of the dispensing apparatus to thread out therefrom and slide outwardly through a pair of guide disks of the dispensing apparatus, which causes a piston of the dispensing apparatus to push upon a cup seal of a cartridge of the dispensing apparatus, which forces the liquid glue out through the muzzle bore in the barrel of the housing.
