CORRECTION:
THis is a 9x19 Parabellum Blank made by reforming a MAL 5,56 case and trimming before filling and crimping. Probably Movie Blank origin.
A very common method of making Movie-use 9mm Pistol and SMG blanks.
It may have also been done in Malaysia, by SMOE, but unlikely ( they make New 9mm Blanks, to proper 9mm Specs...Blanks made from .223/5,56 cases are about 0.010 " undersized at the head and rim, compared to new, factory made 9mm Blanks.
