All of the literature I have indicates that it would be very similar to a 4" barrel.  What I am reading is that 9 mm Luger (or which ever name you like to call it by) is designed for small handguns, so it is using powders that will develop maximum power in a quick burn.  Everything I read showed between 125 and 133 power.

In one reload book I found one recipe for a slow burn powder that was just under average power.  I wonder if that one might give a little more energy in a longer barrel?

With 115 and 124 grain bullets you should see an increase in velocity of just over 300 fps and muzzle energy of 575-600 ft/lbs.
