At the moment the focus is on the South African development of the 9mmP. In time I will add some info on the history and development of the 9mm, although it is not the main focus of my collection at the moment. The 9mm Parabellum is a collection in itself with thousands of different specimens, My collection is more of an accumulation of a few cartridges. (Erlmeier, Brandt Ref. 137).
