The breech bolt (31) may then be removed as follows: with the breech bolt unit in the full forward position, gently pry the ejector stud (30) from its seat in the inside of the receiver wall and slide the ejector to the rear and out from under the breech bolt and, then, out of the receiver.īefore attempting to remove the breech bolt, be sure the action slide is disengaged. Pull the cartridge cutoff (29) out of receiver. Note that the carrier assembly (60-65) may be removed from the guard by unscrewing the carrier pivot (64), which has a left-hand thread.įurther disassembly of parts contained within the guard assembly should not be attempted, and replacement of parts 50 through 59 should be made only by a qualified gunsmith.

Nevertheless, the Model 12 remains beloved by tens of thousands of sportsmen who refuse to retire their “perfect repeaters” or think less of them.Īfter first ensuring that the gun is unloaded and the chamber is empty, place the receiver in a properly padded vise with the trigger guard upward to facilitate disassembly. By the early ’70s, though, the pump shotgun in general had lost much of its appeal, and the old warhorse was relegated to the heirloom and collectible sector of the market. Finally, in the late 1960s, the Model 12 was deemed too costly to keep in production.Īttempts were later made to reduce its cost of manufacture, and limited sales of original-type guns were offered through the custom shop. That “quality at all costs” approach eventually proved the Model 12’s downfall, however, as it collided with the reality of modern-day labor costs and manufacturing methods. Numerous machine operations, some complex in nature, were required to produce the receiver, and Winchester boasted that only the best steel alloys then available were used in the gun’s manufacture. It is of the old school, wherein the bolt locks up to a forged, machined, blued-steel receiver, and walnut serves for the buttstock and slide handle.

The gun’s basic mechanical layout-credited to design team chief Thomas Crossley Johnson in the company’s post-Browning partnership era-remained virtually unchanged throughout its life. In its various guises, the Model 12 would distinguish itself through countless victories in the game fields, trap and skeet ranges, and in both World Wars. sporting version came on the market in 1934. Without bayonet lug and cooling sleeve, it was listed in the Winchester catalog as the Model 12 Guard and Riot gun. “trench” model with 20” cylinder-bore barrel, perforated cooling sleeve and detachable knife bayonet was introduced in 1917. Two years after its introduction, it was available in both 12 gauge and 16 gauge. The Model 12 was initially offered in 20 gauge only, which made it the first Winchester shotgun of that gauge and the first hammerless slide-action repeating shotgun to bear the Winchester logo. Some of its fans have even gone so far as to agree with the company’s appellation of the gun as “the perfect repeater.” Winchester’s Model 12 slide-action shotgun has won the praise of hunters, competitors and soldiers alike during the 90 years and nearly 2 million pieces made since its 1912 introduction.
