Prized by shooters and collectors throughout the world, the unique patented Westley Richards hand detachable lock (droplock) side by side action is supremely built for ease of use and maintenance in the field. The hinged bottom plate allows the locks to be removed from the action for cleaning or, in the unlikely event of failure, replacement.With the stunning scallop backed action built on proportionate sized action frames depending on gauge this gun really deserves its fine reputation.
