TRIGGER GUARD AND TRIGGER PLATE The strong trigger guard, machined from a single piece of steel, elegantly blends into the trigger plate via two rounded reinforcement ridges.  Even in this case form and function are wisely intertwined. TITANIUM TRIGGER Exclusive prerogative of the most prized shotguns, the trigger of the Beretta Perennia is formed from solid, lightweight titanium.  This premiere material guarantees the durability and reliability of use, even in the most difficult hunting conditions. The mirror polish highlights the harmony of its shapes.
