Engineering Around Genius: Winchester’s Forgotten 1911 SL

Way back when, “A man’s word was his bond.” But, in 1901 the bond between two powerhouses in the firearms industry was broken.  T.G. Bennet, President of Winchester, and John M. Browning (JMB) had come to an impasse over how JMB would be compensated for his latest creation: the Auto 5 shotgun.

Perhaps it was T.G. Bennet’s failure to foresee that the world’s first reliable self-loading shotgun would be a hit with Winchester consumers. Or maybe it was John Browning’s demands for “royalties” on this gun, rather than selling it outright as he had done with every other gun for the previous 17 years. Either way, the two men parted company, JMB leaving with his prototype and all of its patents and Winchester without a self-loading shotgun.

The Beginning

The Winchester 1911 SL (Self Loader)

By 1902, Browning’s self-described “best achievement” is being produced by Fabrique Nationale in Belgium and by 1913 over 60,000 Auto 5’s have been sold! Meanwhile, T.G. Bennet is barking at his engineers to create a shotgun to compete with the Auto 5!  Now here is where it gets really interesting. Remember that I said the JMB left with all the patents? While Winchester did pay outright for Browning’s gun designs, they also researched and filed all the design patents in JMB’s name!  Try building a lever gun without a lever or a revolver without a cylinder and you might get an idea of what Winchester engineers were facing trying work around JMB’s patents!

Winchester 1911 SL Long Action compared to the Auto 5


One of the design elements that did make it into the Winchester 1911 SL  (and several other shotguns, rifles, and even pistols) is its “Long Recoil” system.  In operation the barrel and bolt lock together under recoil as they move rearward, compressing a recoil spring until stopped by the receiver.

At this point, the bolt remains in place as the barrel returns forward. While most guns with which we are familiar extract the hull from the chamber, in this set-up the chamber moves away from the hull. An ejector is fixed to the barrel extension and as the barrel moves forward the ejector makes contact with the hull’s rim driving it from the gun.  If the gun is empty the bolt will remain locked to the rear, if a fresh shell is released from the magazine tube it will trip the bolt allowing it to move forward powered by the action spring, thus chambering that shell.

Some Oddities

If we look at the gun as a stand-alone piece, the Winchester 1911 SL is an odd character. If you were to hand one to someone unfamiliar with it, one of the first comments would be, “How do I check the chamber?” or “Where is the bolt handle?” The answers are, “With some level of difficulty,” and “It doesn’t have one!”

To work around the bolt handle patent, the barrel is wrapped with a knurled section a few inches back from the muzzle. Being very careful to have the muzzle pointed in a safe direction, one pulls back on the barrel some 3” in order to cycle the bolt fully to the rear.  This “feature” has been called a “widow-maker” as it is rumored that some halfwit discharged the gun while cycling the barrel to the rear with the butt of the gun on the ground and the muzzle pointed at his face. Personally, I don’t believe it (or maybe I do if half the dopes on the internet actually own guns).

Another oddity is the front sight. Now, on just about every shotgun I have handled a bead is present unless it is a dedicated slug or 3-gun unit where a rifle sight may be present. However, the funky looking appendage on the front of the 1911 SL is nearly magic.  From about any angle it looks out of place, but when sighting down the gun as if to fire…a bead front sight appears!

Take-Down Guns

“Take-down” guns are not a new thing as witnessed in this 100-year-old gun.  That lone screw at the rear of the receiver? Yup, depress that screw’s lock button and spin ‘er out and pop!  Off come the buttstock and trigger assembly, fire control and all!  Ok, that is kinda cool, but how about the fact that you can fully load the magazine and chamber a round and then pop the gun into 2 pieces?  Couple that with the ability to shorten the barrel to flush with the end of the magazine tube without impairing reliability and you have me picturing this gun being used in a crime novel.  I know that my buddy Clay Martin could weave this into another really cool book!

Now, if the only two weird features were the funny front sight, and charging the gun by grabbing and “cycling” the barrel, the gun would be ok. But the biggest JMB patent item that Winchester engineers could not get around led to the demise of the 1911 SL after a few short years of production.

Browning’s Patent

Winchester 1911 SL Buffer vs. Friction Brake of the A5

Browning’s patent on the Long Recoil Action “Friction-Brake” and Winchester’s awkward substitute for that vital element had the 1911 SL on life support from the get go!  Take a look at the photos and you will see the heart of the Auto 5 and the band-aid on the 1911 SL.  Present on the Auto 5 is a little bronze ring with its beveled edges and a barrel hangar and washer with corresponding internal bevels.  As all that mass of the barrel breech block moves rearward under recoil those “bevels” constrict the friction brake around the magazine tube. The friction brake dragging on the magazine tube slows the works down a bit and that greatly reduces the impact of a couple of pounds of reciprocating weight banging into the receiver! It was that simple and elegant design that kept the Auto 5 humming along while the 1911 SL beat itself and its owners into submission.


The Winchester 1911 SL had to use a laminate stock because the conventional stocks would splinter and crack!

Winchester tried to mitigate the pounding of “man and machine” by employing a pair of fiber buffers between the incoming barrel “battering ram” and the face of the receiver.  I imagine it was better than nothing, but not enough to save the gun. In fact, one of the cool “features” of the 1911 SL needed to combat the beastly recoil was the first commercial use of a wood laminate in the buttstock! Why? Because the conventional stocks would splinter and crack!  Necessity is the mother of invention. Another notable unhealthy design element on the 1911 SL was the action spring “running free” inside the wood buttstock rather than captured in a steel tube as on the Auto 5.  I can tell you the resulting wood shavings don’t work so well as a lubricant.

The Winchester 1911 SL’s action spring “running free” inside the wood buttstock rather than captured in a steel tube as on the Auto 5.

So after 14 of years and fewer than 83,000 Winchester 1911SLs produced (including some beautiful Trap Models), the buying public had had enough. While the Browning Auto5 and JMB’s brilliant Long Recoil Action soldier on for better than 6 decades, Winchester’s efforts to engineer around genius was dropped into the dustbin of history.

I can’t help but wonder about the outcome if T.G. and JMB  had worked things out. If JMB got his deal? If Winchester had built the Auto 5? Certainly, both men would have been all the richer, but Browning would never have seen his name engraved on the side of his Best Achievement.  As a collector of many JMB designs (including several Auto 5’s) I am pleased that Browning’s name is emblazoned where it belongs.

    I inherited a 1911 SL from my grandfather and it was made in 1916. I watched him shoot it occasionally throughout the years but didnt know enougg to appreciate it. Thanks for explaining its history and function. I thought it was broken because there was no charging handle.

    A very interesting and fun article. Keep them coming.

    I have one that I bought at a garage sale 30 years ago for $50. I gave it to my brother to replace the Model 1911 he had that was stolen from him. My brother died a little of a year ago and I got the 1911 back. I took it to the range recently and discovered that it now fires when you pump the barrel to charge it. Not a pleasant thing to happen when your holding onto the barrel. Not sure what the problem is but it is too dangerous to use and I am not sure there are any gunsmiths around that are familar with the design.

    Great video! Keep more of these coming. I really enjoyed that!

    Like Robert I was surprised at no mention of the Remington. The Remington is every bit the gun that the A5 is. I have two manufactured before 1920 that still shoot very well. Browning’s design was a good one.

    Unfortunately fewer of the younger crowd (40s and younger) know much about the Remington 11. I was selling a Browning to a guy in his thirties through Armslist and when we met to complete the sale he asked me if I had any other guns for sale. When talk got around to the Remington 11s he didn’t know what I was talking about. And he was supposed to be a collector of guns and not just Brownings. I don’t know if the lack of knowledge is due to the snobbery that sometimes gets connected with the A5 in collector circles or if it is just due to the lack of information coming out of the shooting press.

    My brother-in-law had a Winchester 1911 SL when I was a teenager. Having grown up shooting a Remington model 37 light weight shotgun in 12 gauge, I thought I was pretty well immune to recoil and flinch. After shooting the 1911 Winchester, I found I was not immune to its recoil. My brother-in-law only had it for one quail season, and then found someone to palm it off on.

    Patrick, great article and vid. Keep em’ coming.

    Thank you Patrick. I look forward to seeing more of what you have in the back of your safe(s).

  • PeterC March 19, 2018, 11:14 am

    I had one, briefly, many years ago. It was an ungainly mutt, very unpleasant to shoot. I like weird guns, but this was ridiculous!

  • Tailgunner March 19, 2018, 11:12 am

    Great segment. Winchester’s greed cost them a fortune. Read Browning’s letter to Bennett after their meeting. Fascinating!

  • Robert Bowden March 19, 2018, 10:21 am

    I am totally surprised that your whole article compared the Winchester 1911 SL to the Browning A5. Surely you know of the Remington model 11. As a fact, the FN Browning was no competition to the Winchester since JMB had already sold his patent to Remington for manufacture and distribution in the USA. Remington welcomed the patent and had no problem paying a royalty to JMB for every shotgun manufactured. FN was given rights to manufacture and distribute the shotgun in all areas of the globe except the USA. There were far more Remington model 11’s and pre-model 11 shotguns manufactured than FN’s even though the A5 continued to be manufactured after Remington changed to the 11-48. Even though the model 11 and the FN are basically the same shotgun and many parts are interchangeable, the model 11 was Winchester’s competition and should have been comparison shotgun.

    Strange fact on the 3 shot model 11 Sportsman. When introduced in 1931 it had three roll engraved ducks on one side and three pheasants on the other side. We call these three bird guns. The standard 5 shot model 11 had only one duck and one pheasant. Since this was only done for 5-6 years during the height of the Great Depression, not many new shotguns were being sold. So, fairly rare and I bid on everyone I see on auctions.

    Winchester 1911 SL
    I have one of these beasts. I read your article with much interest. I’ve never seen anything else about the gun. The only info I . have is a replica of an old Winchester catalogue, listing the 1911 at $12.00. The ad lists a “selling point” of greatly ‘reduced recoil due to the auto-loading and ejection action. HA ! I have a standing joke with friends…I give them the 1911 and three 12 ga shells. No one wants to shoot the third. It will get your attention. Still…apiece of history. Do these things have any value other than nostalgia?

    • Michael M March 19, 2018, 5:23 pm

      With only 83,000 made I would imagine there would be considerable collector interest and value.

  • Mad Mac March 19, 2018, 8:38 am

    Before you whip out your hacksaw and lop off the barrel of your A5 or 1911 SL to “shorten the barrel to flush with the end of the magazine tube without impairing reliability”, move the barrel rearward until stopped by the receiver and then mark the barrel flush with the magazine tube. That is where it should be cut.

  • Paranoid Geeks March 19, 2018, 5:48 am

    I tried to comment once already but I didn’t see it show up. Trying it again.

    I used to own one of these. It was well manufactured but certainly a flawed design.
    Back in the days of paper shells which could swell with the slightest amount of moisture, I imagine stuck shells were pretty commonplace.
    There are cases of people being injured when improperly charging or unloading the 1911 SL. Including cops who you would think would have more training than most civilians.

    • Godfrey Daniel March 19, 2018, 12:30 pm

      Paranoid, I read the article. It said: “Deputies had already removed the mgazine and were attempting to clear the chamber…”. Wondering how they “removed the magazine”?
