Sized right for concealed carry with its compact handle, the Century 2000 features a 3.5-inch barrel chambered for the stopping power of .357 Mag. and up to 3” .410 shot shells. Unlike some derringers, the Century 2000 has a trigger guard. Other features include an automatic extractor; a rebounding hammer; a retracting firing pin; a cross-bolt safety; and a spring-loaded, cammed locking lever. If you feel the need for a barrel or caliber change after purchase, the Century 2000 will accept all the Bond Arms extra interchangeable barrels.
