I would expect that most Imperial nobles could issue permits to individuals and small groups that permit them to carry light weapons, such as an SMG, ACR or gauss pistol. Maybe a couple of weapons.
Though such individuals would be expected to be fairly circumspect, especially in high-population or high-law levels - such as no fighting at a concert unless the noble is there in person and can step in to say something like "sorry, officer, the dead persons were assassins and these gentle people are my bodyguard."
