NJ used to have a motto, "New Jersey and You, Perfect Together". Yep, just like Tex-Mex chili and hemorrhoids!
Okay, here you go. Establish residence, then get a NJ Firearms ID. $18 for ID + fee for fingerprinting. Then after you get it in, er, maybe, 4-6 weeks, apply for your handgun purchase permits (used for transfer also) $18. Then it's $2 for each actual permit. Er, maybe, ahem, another 4-6 weeks.
Non-LE CCW? You got a better chance of catching a ride on the donkey with Jesus.
The NJFID is all that's needed for ammo (JHP- LEO only) and long gun purchase.
Handguns limited to 15 round magazines.
Oh, and don't forget stupid high property taxes, stupid high real estate prices, 7% sales tax (unless you live in a "economic opportunity zone", I call it...ghetto, then it's only 3.5%), traffic (especially shore traffic in the summertime), massive amounts of immigrants (both legal and illegal), stupid high car insurance, lousy mass transit (especially for the most populous state in the union), probably #2 behind California for two-legged jackasses, schools that turn out functional morons and high utility costs.
Let's see, did I forget anything? Probably.
Sure you want that promotion?
