With a well designed JHP you will notice in a lot of cases that as velocity increases, expansion increases and penetration decreases.(in a soft medium similar to human tissue) All about the bullet design vs velocity vs medium.
I prefer a 124gr however the 115gr 9bple is nothing to sneeze at and has been proven to be effective. Notice the smaller hp cavity on the 9bple bullet vs say a 124gr GD or HST. The smaller hp cavity helps to control the rate of expansion and increase penetration even though the velocity is increased. It is not like the 9bple is traveling really fast either, you are only looking at around 1250fps out of a G19.
