I have one: ordered the day the flyer arrived. When delivered to my local FFL dealer, he offered to buy it on the spot: told him he wouldn't want it, as I had my credential number engraved on it(an option when ordered): he offered me $1,000 for it; said the credential number made it more collectable, not less.
I have no idea, but this gun is going to one of my daughter's; only one who really likes to shoot, and really understands its significance.
I was involved in a shoot out with a bank robber, which took place over the hood of a car, as a very young agent.
