Sidelock actions, on the other hand, are stiffer because the locks are separate rather than internal, but this isn't without inherent problems. For one, the action must be rather square, flat- bottomed and blocky in order for the side plates to join and interlock in a smoothly contoured, stylistic whole. (There are exceptions of course, but n many.) So when you consider the mechanical or stylistic disadvantages of boxlock or sidelock guns, the brilliance of Dickson's approach really begins to glisten like the gold with which the innards of his guns were plated. Since there were no action excavations necessary in his actions, ÃƒÂ la boxlock, and because he wasn't bothered by the need to shape the action so it would mesh neatly with sidelocks, Dickson was free to sculpt the action in just about any shape he desired. And so he did, and the Dickson "Round Action" was born.
