Welcome to the board.
There are several reasons for a gun to be off face.
One absolute is that if there be obvious space between the breech face and the barrels, IT IS OFF FACE.
The lever being so far to the right also makes me suspect something having been done that may not be a good thing.
It could be an expensive fix. With so many reasonably priced used SxSs out there, I would pass on this one.
Best,
John
