Also known as: Winchester Model 12 Heavy Duck Gun, Model 12 Heavy Duck, Model 12 HD

Overview

The Winchester Model 12 Heavy Duck is a pump-action shotgun, a heavyweight waterfowl variant of the celebrated Model 12 slide-action shotgun. Introduced in 1935 and chambered exclusively for the 3-inch 12-gauge magnum shell, it used an enlarged, heavier barrel and a lead-weighted stock to tame the recoil of the then-new Super-X magnum loads. Fitted with a full choke and a hammerless, bottom-ejecting takedown action, the Heavy Duck earned a reputation as one of the finest long-range waterfowl guns of its era.

Notes

The heavy barrel had a larger outside diameter to add mass and offset the recoil of 3-inch Super-X magnum shells, with additional lead weight added inside the buttstock for balance. Standard barrels were 30 or 32 inches, full choke; 32-inch barrels were dropped by the late 1940s. Magazine capacity was legally plugged to two shells for waterfowl hunting under U.S. federal law.

Background

The Heavy Duck was Winchester's answer to the arrival of the 3-inch 12-gauge magnum shell, purpose-built so the extra-heavy charges of the new Super-X loads could be fired comfortably. Its combination of a beefed-up barrel, weighted stock, and tight full choke made it a legend among market and sport waterfowlers, and surviving examples are prized collector pieces today.
