9mm blank is a military pressure round 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 a live round.
Perfect for general use in all 9mm pistols and sub Machine guns.
Recommended BFA for pistol is .187 (3/16) . SMG is .125 (1/8) with 10 inch barrel.
We have used these with great results in everything from the P-38, SIG, Beretta 92
(M 9) and Glocks - to UZI's, Mp-40's and Mp-5's. For all around training and reenactment use this is a perfect one size fits all 9mm blank. We would consider this a good 1/2 flash blank
Browning Hi-Power and P-08 Luger pistols will need a stronger blank to function. For these weapons use this blank.
