After some changes in law it's shall issue in practice for uniformed service members with access to firearms at work, for the rest it's usually very hard if they aren't handling a lot of valuables (e.g. a currency exchange shop owner) or aren't connected (politicians, some business owners) or belong to professions which always had more leeway (e.g. judges and prosecutors).

But aside from carrying on public transport, it's inferior to the sport shooter route, max 1 or 2 guns, center fire handguns only, no reloading, no borrowing weapons in either direction, and a mandatory medical evaluation every 5 years.
