About the Weatherby Centurion

The Weatherby Centurion is a gas-operated semi-automatic 12-gauge shotgun produced for Weatherby, Inc. from 1972 to 1981. Manufactured in Japan by Nikko and KTG, it used a gas-operated action conceptually similar to the Remington 1100, paired with a lightweight aluminum receiver and a high-gloss checkered walnut stock with a ventilated-rib barrel. Offered only in 12 gauge, the Centurion was a sporting and field shotgun aimed at hunters and clay shooters. The improved Centurion II introduced a revised stamped-steel slide assembly before the line was succeeded by the Model 82.

Roy Weatherby, famed for his high-velocity magnum rifle cartridges, expanded the Weatherby line into Japanese-made sporting shotguns in the early 1970s. The gas-operated Centurion was Weatherby's autoloader offering alongside the pump-action Patrician of the same era.

Safety

  • Cross bolt safety

Made in Japan by Nikko and KTG under contract for Weatherby. The original Centurion's slide assembly was prone to breakage owing to the lack of a recoil buffer; the Centurion II revised the slide and lengthened the action tube to address this. Sales were modest and most parts are now obsolete.
