Should mention that this should require changing out the ejector housing... it's potentially dangerous to shoot the .40 upper with the 9mm ejector. Also do we really need two threads being bumped for the same item?

Ejector housing (in frame) is not same as the extractor (slide). Using a .40 upper on a frame with the 9mm ejector can potentially cause the ejector to contact the primer on a round in some circumstances.
