It looks like the break action isn't for loading, it's just for compact transport right? The hinge better be extra rugged if it's going to get bumped around while folded. And I hope you don't get something tangled up in there while it's in your pack.
Plus, I'm not sure it makes sense to add moving parts to the receiver when you can get a folding stock to do the same thing.
It does make it impossible to fire it while it's folded/in transit, which could be seen as a pro or a con depending on your needs.
IMO the best and highest use for this feature is to go shoot sporting clays with it and get the side-eye from a bunch of fudds.
