The Westley Richards Droplock SxS in .410 bore is among the most specialized and technically demanding commissions the Birmingham workshop accepts. Almost always ordered as the fourth gun in a matched set, the .410 Droplock requires miniaturized detachable lock components built to the same tolerances as the larger bores.
