F#$K a duck! (Cocked&Locked raises his hand and admits the error of his ways)
The luger round IS lower pressure, a 93gn bullet at 1220fps
the tok is a 87 gn at 1390, and the mauser a 86 gn at 1410.
That might be what the book says, here's the reality
Factory .30 Luger loads, 5 shots average, Swiss 06/29 4.75" barrel:

.30 Mauser Factory ammuntion out of a M30 Broomhandle 5.2" barrel
Fiocchi 1247fps
Finnish made 7.63 ammo dated 1958 1265fps
DWM 1345fps
.30 Tokarev out of a Tokarev pistol
Sellier and Bellot commercial 1390fps
1986 nny Yugo 1395fps
So the reality is that it all depends on the ammunition. Most .30 Mauser does not go as fast as advertised. Some .30 Luger rounds are smoking (Before you open your mouth, .30 Luger rounds for carbine had identifying marks on them.) None of these rounds tested are "carbine" rounds.
I do feel that ammunition manufactures are downloading the older cartridges now a days. Fiocchi's .30 Mauser round has one hell of a BANG when it goes off, but it does not do what their catalog states. Same goes for Winchester's .30 Luger round. Great brass for reloading, but the factory loading sucks.
If you want to see what the old calibers can do, find older ammunition.
They do have a 9mm bottle neck cartridge, it's called the .357SIG
