A question I often receive is: Can I let my friend use my firearm at a target range if they don't have a Firearms ID card?
The following is a summary taken from New Jersey Gun Law Guide (Nappen & Gilber) page 163:
Under New Jersey Statue 2C:58-3.1 a firearm may be temporarily transferred to a person at least18 yrs of age whether or not the person receiving the firearm holds a New Jersey Firearms Purchaser Identification Card or a New Jersey Permit to Carry a Hangun. The firearm must be transferred for the sole purpose of target practice, trap or skeet shooting, or a competition on that firing range. The transfer of the firearm shall not be for longer than eight (8) consecutive hours in a 24 hour period. The legal owner of the firearm must remain in the actual presence or directly supervise, or have another competent person supervise, the person to whom the firearm was transferred. No firearm may be transferred to a person who does not meet the qualifications under N.J.S. 2C:58-3 for obtaining a New Jersey Firearms Purchaser Identification Card or a New Jersey Permit to Purchase a Handgun.
