They aren't interchangeable. I tried to "stretch" the 9mm tube, but that didn't work. There is an internal size difference, but not worth trying to get to work either way. Stick with stock for reliability... the most important thing. The only mods I could get away with involved replacing the plastic base plates with the 9mm metal ones and even then I needed use a 3/32"x 3/4" Inner Diameter neoprene O-ring to preclude pinching, especially by the .40.
