Winchester Model 1400 12 Gauge Semi-Automatic Shotgun, Early 1960s Production, 20-Inch Vent-Rib Full-Choke Barrel
Winchester’s first gas-operated autoloader, the Model 1400, offered shooters a lighter, faster-cycling alternative to recoil-driven designs. This early first-generation example (1964–1968 block) carries a factory 20-inch vent-rib barrel silver-brazed to proof steel, a fixed Full choke, and the distinctive alloy receiver that keeps weight around 7.5 pounds. A walnut stock with factory red ventilated recoil pad and “W” grip cap rounds out a configuration prized by collectors and hunters alike.
Condition
Overall Condition: Good condition, showing some signs of prior use and handling.
Bore Condition: Good – clean, well-maintained, minor wear marks.
Specific Condition Notes: The metal surfaces exhibit scattered scratches and blemishes consistent with field use, but remain free of corrosion. The bore is bright and shiny with no pitting.
What’s Included
- Winchester Model 1400 12 Gauge semi-automatic shotgun as described
This Model 1400 features Winchester’s gas-operated action, designed to reduce felt recoil and reliably cycle 2 ¾-inch 12-gauge shells. The system vents gas forward, helping keep the lightweight alloy receiver clean and functional.
The 20-inch barrel is shorter than most production 1400s, giving this shotgun quick handling for upland game or dense cover. Its ventilated rib and brass bead provide an unobstructed sighting plane, while the fixed Full choke delivers tight patterns for extended range.
