Ammo is going to have a bigger impact on sub/super. Typically your 115gr/124gr will be super and your 147gr/158gr will stay sub. The longer barrels will have an increased velocity, so going transonic or even supersonic is possible with some 147gr. My 7" 9mm barrel has kept all 147gr I've tried subsonic.
*info based on factory loaded ammo...handloads will differ based on recipe.
