If you are really worried about the LAW ask your local fire chief (at the fire station) he will help you out lead you in the right direction
This may or may not work, most of The local fire department are for emergences and public service, they do not enforce the laws and most of us do not know all of them. If we have a question we have to go to the investigators (fire Marshall's office), the local police department or other souses.
think that the limits in Maryland are less for safety than they are back-door gun control. Otherwise, they would have storage container requirements for small amounts of powder and realistic limits on smokeless and black powder storage. Maryland is a wannbe California pushing for the same "evil assault weapons" BS and now wanting to adopt California vehicle emission standards
This is somewhat true The current Governor is not pushing for new gun laws but he has not done anything to make it better for gun owners.
I sent him a letter a few weeks ago about changing several laws I have yet to hear anything back from him.
