Yup on the zoning.I've looked up becoming an FFL. The problem became zoning. I would not be able to operate an FFL out of my house. If you can swing a storefront or have a personal business address, perhaps this would be easier.
I'm still wondering about the legality of a State (MD) changing the Federal rules (>29" directly through BATFE) to their liking? Yes, a state may have more strict rules than the Federal rules but to have the ability to work in cooperation of a federal agency baffles me. Circa 2013 - 2014 some <29 got through and many were disapproved. Is >29" in COMAR and where exactly is this within BATFE. What might Frosh change this to this year?
I hope I made my concern clear.
Good Luck OP, enjoy the hobby!
