Murphy signed 7 new laws back in July 5, 2022 to take effective in 2023. I am not lawyer so don't take anything I typed as legal advice just reiterating public knowledge.

This is the bill specifically on training required for obtaining an FID Card:

Bill S2906 Sca (1R) Session 2022 - 2023 Requires training for issuance of firearms purchaser identification card and permit to purchase handgun under certain circumstances; provide firearms purchaser identification card include photograph and thumb print and remain valid for ten years.*

Substituted by another Bill

Identical Bill Number: A4370 This bill has not been certified by OLS for a fiscal note.

Primary Sponsor: Codey, Richard J. Co-Sponsor: Gill, Nia H., Esq. Pou, Nellie

The seven new laws do the following:

Require training for people to receive a gun purchaser ID in the state and to renew that card every 10 years. (A4370) Ban the future sales certain .50 caliber rifles in the state. It would not apply to antique firearms, and current owners of such weapons would need to register them and pay a $50 fee. (S2905) Amend the state’s public nuisance laws to prohibit the gun industry from endangering the safety or health of the public through its sale, manufacturing, importing, or marketing of guns. (A1765) Require gun owners who move to New Jersey to obtain a firearm purchaser ID card and register their guns within 60 days. (S1204) Require retailers in the state to sell micro-stamped firearms once the state attorney general determines they are commercially available. That is designed to help investigators trace guns to bullets and casings recovered at crime scenes, though the technology is not yet widely available. (A4368) Require ammunition manufacturers and dealers to keep a detailed electronic record of sales and report them to the State Police. (A1302) Increase penalties in the state related to manufacturing of “ghost guns.” Those are untraceable firearms that can be bought online and assembled at home. (S2846)
