welcome to TFL
I have a Gorgeous .32 LW Seecamp that was my late fathers. It is relief engraved and stunning and I would LOVE to carry it on a daily basis.
IF the gun has any emotional value to you, I would advise against carrying it, daily or other wise.
Besides the wear on the finish that will inevitably result, the biggest reason not to carry a gun with irreplaceable emotional value is the risk you will lose it. And I don't mean, "it fell into the swamp and sank out of sight", I mean that if you ever have to use it defensively, the police WILL TAKE IT.
It is evidence, and stays evidence, until ALL legal matters involved are concluded. This might be a matter of days, or weeks, but could be months or even years, depending on the specific involved. And the police are not noted for taking good care of guns in "evidence". Rust, finish, and even mechanical damage are not unknown, and in some instances, not terribly uncommon.
Additionally, there is a risk that even with you completely exonerated and all legal proceedings completed, you still may never see that gun again. There are /have been places where the authorities simply will not return your gun, and may even destroy it, and cut you a check for their idea of its value.
I'm not in NJ, and in no position to offer any advice about their laws, get an actual NJ lawyer for that. Do not take any legal advice from any cop as valid or correct. They may (or may not) give you what they believe to be an honest answer, but it's not their area of expertise, and there is no legal requirement for them to provide you valid information. Its not their job.
And saying "a cop told me it was legal" is not a very good defense.
If it is any defense at all...
