gun transfer laws in nj

Hey everyone I was wondering if anyone knows any info on transfering gun ownership in New Jersey. I live in NJ andI purchased (in NJ) a Smith & Wesson 357 back in the mid 80's. My brother-in-law who also lives in NJ now wnats to buy it from me. Does anyone know what we need to do to accomplish this? Any info would be appreciated.

I'm pretty sure you have to go to a place or someone that has an FFL. They can do that transfer and all the paperwork that needs to be done.

A former FFL friend told me only thing needed is a bill of sale. No registration or hundgun permit required for private resale in NJ.
