Made in 12, 20, 28, and .410, the gun’s barrel can easily be changed for clays or game. F3s have a rifle-style trigger whose inline striker provides lightning-fast lock time. Concealed in the stock is a balancing system to compensate for longer or shorter barrels. My F3 has been to Argentina twice and been shot extensively--possibly 15,000 to 20,000 rounds--over three years without a hitch. $7,250.
