Welcome to the forum.
I think many people consider this model a triumph of marketing over practicality, but the fact that it shoots .410 shot shells, .45 colt and .45 ACP or auto rim interchangeably makes it a clever design.
This gun would never have come to production if Taurus hadn't had some popular success with its Judge model. I suspect the Governor is a better made gun, but I don't know how big the market is. S&W will sell a few, but the gun may go out of production fairly quickly because the market for it seems limited to coolseekers and guys who may encounter both rattlesnakes and wolves on the same hike.
I wouldn't mind having one, but I wouldn't be ferociously disappointed if I never got around to buying one while they are available.
