The military ammo has been made by Win and Fed, maybe others? Pressure can go up to 42K psi on the Win NATO stuff, US M882 is usually lower, max case mouth pressure of 36,250 psi (Same as SAAMI +P). Mid case pressure can be much higher though.
Bullets from 112-124 grains. Get about 1180 fps from the Win NAT0 stuff in most pistols w the 124 bullet.
There is US 9mm military ammo loaded to higher pressure intended for use in smgs only too, not the M9/M11 pistols. This may be the hard primer stuff you are referring to? Some NATO ammo is also intended for smgs only, and is also loaded to higher pressure with harder primers (but not always). You can shoot it in pistols, but it is harder on em.
