Thanks for that extended comment, dreadi. I particularly had NOT considered the takedown point - one of his 22 rimfire rifles is a reproduction Winchester 1906 that comes apart, and might fit in a reasonably compact box. His M1 will be a different matter, when the time comes.

We're flying Southwest, nonstop, so I think I'll start off taking several of his handguns in checked luggage. SW policy allows multiple guns in a single hard case, so I only have to buy one case and one lock to take his two SIGs. His Walther 22 is in its own case, and I just have to confirm with SW that they're OK with multiple hard cases in a single piece of checked luggage.

Thanks again for the continuing help.

You're welcome. One more thing about handguns that I like to tell people, just in case they have the strings to pull. You can legally ship handguns via common carrier. The trick will be finding a common carrier that will do it from a non licensed person to a non licensed person or to yourself, and any other legalities that might be involved.

About three years ago I mailed a rifle to myself from Seattle to Florida. With insurance, tracking, signature required, it was about $75.

Shipping a rifle should be more in the $35 range, UPS or USPS.

Or FedEx, but I hate those fuckers.
