50 ROUNDS PER BOX
9mm blank is a military pressure 1/2 load blank designed to be safe in the pressure intolerant P-1/ P-38 family but strong enough to give good sound / flash in all 9mm weapons. Sound simulates the lower end a live round in volume.
Good general use in most 9mm pistols and sub Machine guns.
Recommended BFA for pistol is .187 SMG is .125 with 10 inch barrel.
Browning Hi-Power and P-08 Luger pistols will need a stronger blank to function. For these weapons use this blank.
