9x19 unknown (quick defense cartridge from M.E.N)

Does any one know what this 9x19 is? The bullet has an unusual shape and appears to be two piece.

Thanks,

Paul

It is a “quick defense” cartridge from M.E.N. You can see a section of the cartridge here: http://www.sammlermunition.de/Spezialmunition_Pistole.htm and just search for the word “defense” 2/3rds of the way down the page to find this pic:

And who’s site is that anyway, I just came across it while looking for a good pic of a quick-defense cartgridge, and it is a great website!

there is also a complete description of these bullets in “Handbuch der Pistolen-und Revolver-Patronen,” by Jakob Brandt and Alfons M

DK and John, Thanks for the information
