The reason you cant get more then 3 permits at a time is simple. In NJ, you can only buy a handgun after 30 days have passed since you last purchase, so that by the time you were allowed to buy the 4th handgun, your permits are expired. I know you can get them extended, but come on, this is NJ, you have to check in with the PD just to insure you get the permits before they expire.
