I think everybody should have at least one break action shotgun, whether it's a single barrel or a double. The nice thing about single barrels is they are durable and inexpensive and even at a low price shoot very well. Double barrels are often difficult to get cheap, but if one can get a deal on a good one you can't beat that.
I would suggest going single barrel before taking the $500+ plunge on a double barrel and like post #2 said, shotguns flew off the shelves in 2020 and the double barrels, given the increased difficulty and expense of making them, haven't come back.
It's difficult today to recommend to someone that they pay more for a questionable quality double barrel shotgun over a proven design like a Mossberg 590 or even a lesser, but still very good Maverick 88. That said, I do not like the thought of an inexperienced person in a high stress situation relying on a pump action. I'd much rather they use a double or even a semi auto. Frankly, they'd be better off with a pistol or a semi auto rifle or even a Circuit Judge revolver carbine with .410 shells in it.
