What does express mean in a shotgun?

Express is a term used to describe a type of shotgun action. Specifically, it refers to a double-barreled shotgun with an exposed hammer and double triggers. The term "express" is derived from the fact that these shotguns were originally designed for use in hunting big game, where a quick second shot was often needed.

Express shotguns are typically of a higher quality than other types of shotguns, and they are often used for clay target shooting and other competitive shooting sports. They are also popular with collectors, as they are considered to be classic examples of shotgun design.

Some of the most famous express shotguns include the Holland & Holland Royal, the Boss Over and Under, and the Westley Richards Boxlock. These shotguns are known for their reliability, accuracy, and beautiful craftsmanship.
