I wouldn’t say it’s a gray area. I don’t think it would fall under the category of “handgun” since it isn’t a handgun by definition.

Since most hunting regulations apply to handguns, rifles, or shotguns (none of which apply to the Shockwave) I’m guessing it would be a no-go.

Also, of all of the firearms I’d consider hunting with, something like the Shockwave would be way down at the bottom of the list.
