In an over-under shotgun, the barrel that fires first is typically the one on the top. This design allows for a more streamlined profile and helps with balance when aiming. However, some shotguns may have a selector switch that allows the shooter to choose which barrel fires first, depending on their preference or the type of shot being used.

In a Miroku over-and-under shotgun, you typically have a selector switch that allows you to choose which barrel to fire first. Once you've loaded the gun, pulling the trigger will only fire the selected barrel. After firing the first barrel, you can then pull the trigger again to fire the second barrel. If it's only firing one barrel at a time, it may be functioning correctly, as that is how these shotguns are designed to operate.
The wooden piece under the barrel of a breech-loaded shotgun is called the forend or forearm. It serves to protect the shooter's hand from the heat of the barrel during firing and provides a secure grip for handling the shotgun. The forend can come in various shapes and styles, often reflecting the design and aesthetics of the shotgun.
