My county (rural GA) had an ordinance on the books that prevents the owning of any revovler other than those made by Colt or Remington.
Those firearms being very high priced and therefore un-avialable to recent Freedmen and share-croppers.
Not so different from current proposals to "keep guns out of our cities" (read: where poor people live) or to require gun owners to buy massive amounts of insurance (which poor people can't afford) or pay huge licensing fees (that poor people can't pay).
Racist and classist in effect even when not in intent. But I think a lot of times it's the intent as well as the effect.
