Craig, a Kersten doesn't really work on a sxs for the same reason a Greener doesn't work on an OU: significantly different designs. A Greener, or close copy thereof, requires an extension between the barrels, pierced by a crossbolt which locks into the breech. That obviously does not work on an OU. What typically happens there is that there are projections extending back from the top barrel, on either side of the action, which fit into slots in the standing breech, with bolts engaging both--and also protruding from the sides of the action (like a Greener, in that sense) when it's open, locking in place when it's closed.
Agree with eightbore that this one looks like an odd combination of locking features.
