Wow! Sorry about the run in. Goes to show you should never talk to police, especially in these circumstances.
I mean, what good could possibly come from it? Best case, you get to continue on your way. Worst case is the OP's story, or possibly even worse!
Some of you aren't as stubborn as I am when it comes to talking to police, but there's a difference between a quick/friendly exchange while you and the cop are in line at a restaurant, and a cop on duty rolling up in his cruiser on you. I think you'd probably agree that when you are the subject of an investigation, remaining silent is the best course of action. The officer started off with "got some calls". Immediately zip the lips! How do you know those calls were about a man OC and not a man who just robbed a store?
I would say the fact that the DA's office was called would excuse the officers on the final outcome of the stop, but not the other aspects of it. But what I find astonishing is that every officer on scene, the Sgt, and even the DA's office were completely unaware of the law and assuming themselves correct, falsely arrested a man and confiscated his property! More than 20 months have elapsed since Clark County updated it's code, and in that year and a half, none of these folks have learned this simple law?
It begs the question as to how many other visitors have had their property confiscated and been charged under this code? The Clark County code, by the way, CC 12.04.110 or 12.04.200 are already up to date and preemption is irrelevant here! Was this the code under which you were cited?
12.04.110 Registration of pistols within seventy-two hours.Any resident of the county receiving title to a pistol, whether by purchase, gift, or any other transfer, and whether from a dealer or from any other person, shall, within seventy-two hours of such receipt, personally appear at the county sheriff's office, together with the pistol, for the purpose of registering the same with the sheriff. It shall be the duty of the sheriff to register the pistol, and he may, and is hereby authorized to cooperate in any manner he sees fit with other law enforcement agencies, and with licensed dealers, relative to registration of pistols, so that efficient registration shall be secured at minimum cost and duplication.

12.04.200 Registration of firearms capable of being concealed.It is unlawful for any person with at least sixty days of residency in the county to own or have in his possession, within the unincorporated area of Clark County, a pistol or other firearm capable of being concealed, unless the same has first been registered with the sheriff or with a police department of any of the incorporated cities of Clark County.
