To my eye, the round action, as perfected by Scottish gunmakers, makes the most graceful and elegant shotgun of all. The round action is a type unto itself, neither boxlock nor sidelock. It’s a triggerplate design, meaning all the parts of the lock are attached to the trigger plate. The ejector mechanism of a round action is in the action, not the forend, so there need only be two small holes cut in the action, not the larger slots found in other guns. Because of this, round actions can be made trimmer and lighter than other double guns.
