Hi Michael,
Actually, yes, there is a good chance, but it needs some further investigation
The 9mm versions appear to have some 'meat' or weight added to the rear end of the grip piece. These reinforcements have been described in other threads before. These changes most likely made it into DWM's .30 luger versions of the same era as well.
We also now know, after speaking with former Mauser engineers who were connected to the development of the 1970s Mauser Parabellum, that they had a lot of problems to create a decent 9mm version based on their .30 luger / Swiss inspired model, because of these Swiss changes. Can't give too many specific details, as more will be revealed in an upcoming book on the Post-War Mauser Parabellum.
