Nothing.

Like any other firearm. As long as your issuing authority grants it, you can have it. There isn't a minimum, or maximum calibre allowance.

Remember, all of the .36cal muzzle loading rifles and revolvers are "9mm".

The issue around smaller bore sizes is not the paperwork, but how useful they'd be given the fouling issues associated with black powder...
