All came with 7/8" threads. Note: GX10 is virtually the same gun as a G10 2-finger. Only difference is the GX10 is sold through the Wagner division; G10ís are sold through the SprayTech division. Gx10 is only made in 2 finger, whereas the G10 is made in 2 and 4-finger models. All parts on this page fit both guns.
