"it is easy to lose droplocks, especially when showing off"

You are kidding right?! Where? - at sea on a skiff? WR made a best gun in every sense of the word when they made the DL. Emplying that any A&D is as good is like saying all sidelocks are the same. And that is not to say that the standard vintage boxlock isn't a great gun - it is and many are great buys. But the drop lock is a special thing.
