A hand held paint spray gun having a top mounted paint cup which extends from the rear of a gun body at an angle of 30° ~ 10° to an axis about which the atomized paint is discharged. A retainer ring secures a lid on the cup. The lid seals to both the inside and the outside of the cup. The double seals reduce the risk of paint leakage. Preferably, the gun operates with suction paint feed which is augmented by gravity feed when paint in the cup is located above a nozzle assembly on the gun. To facilitate cleaning and to allow the gun to spray in an upward direction, the paint may be sealed in a collapsible closed bag located in the cup. With the closed bag and the suction feed, the gun will operate when aimed in all directions. The gun is easily cleaned by forcing solvent from the nozzle assembly back into the bag and disposing of the bag containing any remaining paint and the used solvent.
