I'ts more work than in the other 49...
But not impossible if you play by the rules
First she will need to go down to her local PD.
She will need to file for the Firearms Identification Card,
and a Handgun Purchasers Permit. You must must have
both! She will need a Money order for 49.00 made payable
to the State Police, and Usually a check for 12 bucks to
the Local PD. She will then be fingerprinted, It WILL take
90 days!!! The Law in NJ says they have 30 days, but
it's an unenforceable law since the S.P. do the background check
the Old way (Paper Request), and the local P.D. chiefs have
routinely refused to issue permits with out the S.P.'s
check in hand. The kicker is you still have to wait the 3days
and pay for the NICS fees at the dealer.
Also never call and ask the PD when the permit will be in
they will shuffle you to the bottom of the pile and It'll take
longer. (Several Local Leo friends have confirmed this)
