So I have had an interest in firearms for a long time. Not as a tool for aggression as most people will seem to perceive them as, but as a relaxation in a firing range, or self defense if it ever comes to that in a dire situation. I will be turning 18 this September 4th, and I want to go to a firing range for the first time soon after. But I want to get some information clarified to me. I live in the state of New Jersey, and I am aware of the firearm laws here. I cannot own a semi-automatic rifle/shotgun until the age of 18, and I cannot own a firearm until the age of 21. Now here is where my question comes into play. My father (whom passed away only a few years ago of cancer) was a police officer, so understandably, he had a few guns from his time. He owns a Stainless Steel High Standard 22 Magnum Derringer, a Stainless Steel Smith & Wesson Model 36 Chiefs Special .38 Special, and a Blue Steel Sig Sauer Model 230 .380 Semi-Automatic. All of these weapons are in a great condition and are capable to be safely fired. My question is, due to the law saying I cannot legally own these weapons myself, would I still be able to legally bring these 3 firearms to the shooting range, purchase ammunition for them there, and use them at the range? Or at the age of 18 would I only be able to bring a rifle for firing?
