Stan and I have both noticed that the 680 series Berettas are very easy opening, for the same reason the Model 21 is easy opening. The ejector springs are compressed against the breech face. When the top lever is released, the ejectors just fight to get loose. In the Beretta, the ejector springs are cammed very gradually when closing the gun, unlike the Purdey. The Beretta is a great piece of engineering, the Purdey, not so much.
