If she was just delayed, if it’s not denied or approved, she can pick up the gun in three business days.
“If the FFL has not received a final determination from the NICS after three business days have elapsed since the delay response, it is within the FFLs discretion whether or not to transfer the firearm (if state law permits the transfer). If the FFL transfers the firearm, the FFL must check no resolution was provided within three business days on line 21d of the ATF Form 4473.”
She pointed this out in the update, but said that this dealer (Sportsmens Warehouse) will not sell unless it comes back approved.
