For who is interested in the story of these models that are more and more appreciated by collectors, I suggest this short introduction here:

Interesting is that the Mauser Parabellum made by Mauser from 1970 onward are the only Luger for which the Original Production books are still available:

Sometimes people is not very inside the different models and variations produced by Mauser so before considering a pistol a "shooter" model please double check just to avoid that you use a rare variation as shooter...
