It doesn't really matter where in the world it was made. It should work when new, and it should continue for a long time. While a Silver Pigeon isn't Beretta's most expensive gun it isn't cheap when compared with the shedloads of genuinely cheap Revo and ATA (and the rest) guns. A Silver Pigeon is a product from the oldest firm of gunmakers in the world, and they have a reputation to keep.
A new gun should be supplied - yours is plainly defective and there really shouldn't be any question of repairing it at this early stage. Perhaps another approach to the dealer should indicate your intention to pursue the matter with Trading Standards and the Small Claims Court. The latter is something that really has teeth - nobody wants the poor quality of their products or service standards bandied about in court (which means the press, too). It' s a simple procedure with a high chance of success.
Any repair will mean that the gun has been modified from its new state. New barrels or ejectors may be fitted, but you could reasonably claim that you have little confidence in the rest of the gun if something as fundamental as the ejectors don't work.
Have we learned the identity of the dealer yet?
