BadAsh... Where In NJ are you?
I am in Hudson County, and it took 70 days for my FID and pistol permits, and that was including the the Thanksgiving/Xmas/New Years holidays.
The state's mandate of 30 days is unrealistic, as it assumes you're going through a police department that is as well staffed as the State Police are.
Where I am, there is one Lt. that does it, and nobody else at that PD knows their ass from their elbow about the process. Or, you're stuck going through a PD in a town that elected a Anti-gun Police chief, and he's dragging his feet on signing it.
I know 30 days is "the law", but if you actually want your permits, I recommend that you refrain from complaining...
