The BSS trigger is a mechanically switched trigger. It does not require any inertia to switch to the other barrel. It does have an inertia weight that you can see in the picture I posted. This weight is to block the trigger during the recoil phase to prevent inadvertant discharging from the finger hitting the trigger at the back of the recoiling movement of the gun. Commonly called an "inertia blocked trigger". So, it is not working correctly if you can't fire the second barrel when dry firing.
