Set of five 9×23 (9mm Largo, 9mm Bergmann–Bayard, 9mm Bayard Long) dummy rounds or “snap-caps”. This was standard pistol and submachine gun cartridge of both Spain and Denmark from WWI through WWII. It was also used by the Germans during WWII.
Available with spent primers remaining, empty primer pockets, holes drilled in the cases, or rubber inserts added to the primer pockets.
Great addition to your re-enactment display, dry-fire training, etc.
Thanks for looking!
