This Sintox 9 mm Luger has a notched rim. Someone told me this is indication of a dummy but I’ m NOT going to try this out as I don’t find a confirming source. But yes, is there something special to the cartridge because of the notched rim?
This “coin edged”, rim on a lot of European makers product often note the round being a high pressure test or Proof round.
Exactly, so do not try to fire it in a gun!
An unexpected little treasure…I think the seller didn’t know either! Thank you, gentlemen, as usual.
