The single attachment of the Westley Richards guns was sufficient for the black powder loads of the day, even under substantial use, and Westley Richards' highest-grade guns did not have extra locking points. But I expect double and triple locking systems to be stronger and therefore, in greater demand by a shooting public rather obsessed with the strength of breechloader actions. Most early actions had a single attachment point, wherever it was. It looks like by the time gun actions were heading towards a kind of standardization dictated by market forces, double and triple systems were the norm.
