A removable fluid insert may be placed in interchangeable (airspray and HVLP) spray heads with the fluid insert being either a pressure fed device which depends downwardly from the front end of the gun into a pressurized cup or via a connection to a pressurized fluid source or may have an upwardly directed insert which will take fluid from a gravity cup. A simple air swivel also adds ergonomic benefits.
