Is there something more specific you are looking for? Load data is load data, whether you are shooting it out of a 3 inch barrel or a 16 inch one.
Perhaps this might help?
http://www.ballisticsbytheinch.com/9mmluger.html It shows 9mm ammo really not getting much velocity gain out of barrels longer than 5".
If I am missing what you are trying to say let me know.
