RE: FFL, how to get it?
I've had an 01 FFL since '84 or so. Don't have a store front, don't need one. Also, you probably don't really need the kit; if you contact ATF they will send you the application, and you can buy a bound book anywhere. As someone said, though, you do need to check zoning. This was one of the Clinton scams for getting rid of a lot of us. No green light from whatever zoning you might fall under, no FFL. After the first $200, it's $90 for every 3 years. One other catch, since you have to be 'in the business' to get the FFL, you have to file as a business for fed tax purposes, which means you have to show a profit in something like 3 or 4 out of every seven years.
Good luck.
