Yes, 9mm ballistics are commonly quoted for a 4" barrel. Others, like 38 Super for instance, from a 5" barrel. One reason why the Super may appear to be much more powerful than 9MM. When both are tested in 5" barrels, the assumed superiority of 38 Super over 9mm is not always consistent with reality.

In any case, some actual chronographed velocities for the Winchester Q4318 124 grain NATO ammo:

4" Bbl. = 1165 FPS
5" Bbl. = 1214 FPS
5.9" Bbl.= 1244 FPS
16" Bbl. = 1319 FPS

2" revolver = 1079 FPS
3" revolver = 1169 FPS

FWIW the IMI 124 NATO averages 3-5% faster in my guns.
