Was there any regulation of hand-held blasters, slug-throwers and other weapons?
I know that according to this question Han illegally modified his blaster, so surely there are some regulations on the modification of blasters. Just to make it clear, I am asking about blasters and other ranged firearms that a single person could hold, not ship mounted lasers (already asked.)
So what laws governed the use and ownership of blasters, slugthrowers and other ranged weapons in the Star Wars universe?
EDIT: I am asking specifically about regulation during the Rise of the Empire, Rebellion and New Republic eras (From 30BBY - 30ABY.)
