... and I am still trying to buy one from out-of-state as we speak, although the effort is not going very well.

But I have a question: The one I am pursuing does not have its original factory box. How does it read on the factory box for these late-produced guns? Should the selling dealer and my in-state FFL write that gun up as a "4506" or as a "4506-1" or something else?

I'm not that worried about it as long as the two of them are consistent with each other but it would be kind of nice if it matched what it would have said on the original factory box.

I live in moonbat MA after all and you never want to give nanny government any reason, no matter how small, to zing you.
