Two point slings hooked to the underside of the shotgun are fine for "over the shoulder" carry; like GIs on a march or hunters oftentimes do.
If you want to carry it across your chest and go hands-free that is a horrible way to sling-mount a shotgun. For that, you have to put attachment points on the top (or very high up the sides) so that gravity keeps the shotgun trigger guard and stock wrist oriented down.
Just sayin'.............
