Question for you FFL's out there. I purchased a handgun last thursday, Maryland has a 7 day waiting period which really means on day 8 you can pick up the gun. I go in to the store today and was told they are still waiting on the NICS number. It's been 8 days, I thought this was supposed to be an instant system and if after 3 days no response then you can proceed with the sale? The shop owner said he can't legally transfer a firearm without the NICS number. Is that true? and is this common? I realize Maryland might have some weird laws and I'm not looking for a legal answer, just trying to make sure I'm not being given the run around here.
