Winchester Model 12

Often called the perfect repeater, Winchester’s Model 12 pump-action shotgun distinguished itself on game fields, trap and skeet ranges, and in both World Wars.

Winchester 12: Exploded View and Assembly

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. Some of its fans have even gone so far as to agree with the company’s appellation of the gun as “the perfect repeater.”
The Model 12 was initially offered in 20 ga. only, which made it the first Winchester shotgun of that gauge and the first hammerless slide-action repeating shotgun to bear the Winchester logo. Two years after its introduction, it was available in both 12 ga. and 16 ga. The 12-ga. “trench” model with a 20-inch cylinder-bore barrel, perforated cooling sleeve and detachable knife bayonet was introduced in 1917. Without bayonet lug and cooling sleeve, it was listed in the Winchester catalog as the Model 12 Guard and Riot gun. A 28-ga. sporting version came on the market in 1934.
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. 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. 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.
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. Finally, in the late 1960s, the Model 12 was deemed too costly to keep in production. Attempts were later made to reduce its cost of manufacture, and limited sales of original-type guns were offered through the custom shop. 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.

Nevertheless, the Model 12 remains beloved by tens of thousands of sportsmen who refuse to retire their “perfect repeaters” or think less of them.


After 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.

Remove the guard screw (46) and remove the complete guard assembly (45) from bottom of receiver (1). 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. Further 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. Pull the cartridge cutoff (29) out of receiver. 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.

Before attempting to remove the breech bolt, be sure the action slide is disengaged. Depress the rearmost arms of the breech bolt retaining lever (33) and slide the breech bolt almost all the way to its rearmost position. Then, lifting the breech bolt by its back end first, guide the left- and right-hand extractors (38, 41) up through the vertical slots on the inside of the gun’s receiver walls.

Although not normally necessary, the buttstock (47) may be removed by unscrewing the buttplate screws (49) and removing the buttplate (48), after which the buttstock bolt (4) can be unscrewed with a long, heavy screwdriver and the buttstock pulled away from the receiver.

To disassemble the breech bolt, remove the firing pin retractor screw (37) and lift the firing pin retractor (35) out of its seat. Pull the firing pin retractor spring (36) out of its hole. The left-hand extractor and spring (39) and breech bolt retaining lever are removed by drifting out their respective retaining pins (40 and 34). Remove the right-hand extractor by slipping the blade of a small screwdriver between the plunger (42) and the extractor and easing the extractor up out of its hole inside the breech bolt. Remove the spring (43) and plunger (42) toward the front. Reassembly is accomplished in reverse order.

Actually, the Model 12 was not the first Winchester shotgun to be made in 20 gauge. Two 20 gauge Winchester Match Guns, side-by-side outside hammer doubles, were made in the 1880s. I only know this because an old friend of mine has one of the two.

Brian, barrels were never marked 'RIOT,' only with standard choke designations.

Jim wrote:
October 28, 2013

Dan & Joe. Model 12s, apparently at least through 1964, had the ability to 'cycle', i.e. to fire repeatedly if the trigger was held down while the slide was pumped. All or most of the Olin, FNH, Moroku Model 12s have the 'OSHA action'. The trigger must be released and the slide first pushed forward and then back to eject & chamber a new shell.

Brian wrote:

Sorry, I should have said choke markings, not bore. The barrel is for a 12 Ga.

Brian wrote:

Does anyone know if Winchester ever stamped any Model 12 20' barrels with the words 'RIOT' for the bore. Most riot guns that I have seen have 'CYL' markings. Any info would be appreciated.

I have the opportunity to purchase what the owner is claiming to be a Winchester 'Model 12' .410 gauge shotgun. All the research I have been able to locate indicates to me that the 'model 12' was never manufactured in a .410 gauge. The barrel is stamped indicating the gun is a model12. Any insight you can provide would be greatly appreciated. Thanks Kevin

A lot of older M12s have short chambers so you should have it checked before shooting 2-3/4 shells, let alone 3s. I have a 1942 vintage M1897 that is marked 2-3/4 and measures less. Can't decide if I'll have a smith tune up the chamber or if I will load short shells. John - I have also heard that you should not touch the ring between the bolt face and the take-down barrel unless you really know what you are doing. Take it to a smith.

Nice to see some current posts about this shotgun. My son recently received grandpa's Winchester 12 - 12 G. A mixed bag of shot-shells were being shot and a 3' round inadvertently was run through the gun. (The friend thought all guns were chambered to shoot 2-3/4 to 3' shells, so did not mention it was a mixed bag). Round did not eject automatically and had to be manually removed. After that, it was not cycling/ejecting well. Turns out a small piece of the plastic shell is embedded between the 'Barrel Chamber Ring' and the side of the 'Receiver'. Looks like a special tool is required to screw the ring out? Any thoughts on removal of the ring? Thanks! John

I've got a first year production 20 gauge with a 4-digit serial number. It was passed down to me from my dad, and from his dad. It's now 101 years old. I've started in on a minor restoration project, mostly just disassembly, deep cleaning and replacing missing screws and parts. Midwest Gun Works has lots of parts for these old guns. Holding five rounds in the tube and one on the chamber, it can make a great self defense gun, which Is what I plan to do. Those asking "what's my gun worth" - no one can price it without looking at it and determining the condition. A beat up 12 might get $100-300, a pristine model can bring a thousand or more. They vary all over the map. If you want a rough estimate, take some detailed photos and post them on the website, some of the guys there can give you an idea. Or take it into a good gun store for an estimate.

Mod stamped on the barell and typical missing bluing with the nickel steel. no rust no pits and the gun is extremely tight. Anyone know a collector who might e interested? this old and tight of a gun I would like to see someone have who knows and appreciates what they are. thanks

George, I might be a little late here, but this is the site to date your model 12 by serial number. Sorry to hear you will be selling.

is there a site online where I can go from the serial number on my model 12 to the year of manufacture? I've had the 12 guage for more than 40 years and don't know when my father initially purchased it. But it's gotten me my limit in whatever I was hunting for more times than I could count. Now it's time to pass it along to another and I'm just doing research before I put it on the market.

I took my 1925 Model 12 Quail hunting for the first time in 15 years. I mangaged to show those kids with their lightweight Italian Autos a thing or two! Love my 12/12 and will not shoot anything else.

I just had a guy look at my Winchest Model 12. He told me the sight at the end of the barrel was missing. That there was a part that went inside the barrel and that my gun didn't have it. ????

Paul, Either the buyer simply had to have that 20 guage, and was willing to pay that price, or, it must be a premium grade. Are there any other markings, on the pistol grips, engraving, etc.?

Paul, If your Dad was offered $2,500, the Model 12 must have been a special grade. Checking Blue Book again. Be back.

Hi Paul,I just received latest edition of Blue Book of gun values. $1,100 in 100% condition, down to $650 in 90% condition. Add 40% for original box with papers. Add 40-50% for Win. solid rib.Add 10% for pre-WWII. Certain other features could add more value. This is from the Blue Book.

I have a model 12 20ga. and the last pat. date was 7-22-1913. It has a 30in. mod. barrel. It is in excellent condition. A collector said he had all of the model 12 shotguns except for the Model 12 20ga. with a 30in. Mod. barrel. He offered to buy it from my Dad in the early 1960's for $2,500. Dad gave it to me when I finished High-School. Does anyone know what it is worth today?

Hi Jim, type in "Winchester dates of manufacture" on AOL, or a search engine. You will find it there. If you can't find it, put the s/n on our next post, and I will tell you when it was made. Joe

Rick: re: how to get the plug out: I inherited my dad's 12 made in 1936 and found two great currently published manuals for it, which were easy to find online. Winchester Model 12 Do Everything Manual/Assembly/Disassembly/Lubrication/Maintenance, etc by Michael Pugliese - excellent, clear, illustrated instructions. Was about $7. "12GA Winchester Model 12 Handbook" by Ian Skennerton - similar but I think valuable to have both. It cost about $5. Good luck!

James Kirby: The difference is Winchester began manufacturing in 1912 thus calling it the Model 1912. It was shortened to just Model 12 in 1919, therefore yours is made prior to 1919.

I have a 20 ga. which is the best small bird gun ever. However, have not shot it in several years due to not being able to find 2.5 ammo with the short brass case. Is there a place I can order 2.5" ammo for this gun.

We have had Winchester Model 12's and Model 42 (410's) in our family for over seventy (70) years. Skeet, Trap, Field or Self Defense, the Model 12 is proven & reliable. I will never get rid of mine and I am always on the lookout for 12 & 20 gauges in excellent condition. One of the "Best" Shotguns ever made!

Just picked up a Model 12 at the Tulsa gun show last weekend. 30 inch field made in 1954 based on SN - I would rate it at 90% - Paid $350 for it and I think I made a heck of a deal. Anxious to get it out to shoot.
