What Happened to the Winchester Model 1911 SL?

Who doesn’t love a good autoloading shotgun?

Unsurprisingly, the first commercially successful type of this weapon came from the mind of the one and only John Moses Browning.

As is the case with many of Browning’s designs, there was a spark of genius that led to a wildly successful weapon, only this time, Winchester completely fumbled everything and ended up with a shotgun known as the “widowmaker.”

Today we will look at how and why the Winchester 1911 shotgun rose to infamy and faded into obscurity.

The Browning-Winchester Affair

John Browning had a long-running relationship with Winchester by the time he pitched his design we now call the Auto-5. Their previous agreements had Winchester purchasing Browning’s designs for a one-time fee and then producing the firearms.

However, Browning saw immense potential for the Auto-5 to be the next big thing. This time, he wanted a royalty arrangement for every gun sold.

Winchester scoffed at this idea and refused Browning’s proposal.

Prior to their disagreement, Browning was working with Winchester’s patent office. Winchester essentially wrote the patents for Browning’s designs, even before purchasing them.

They were an experienced company, and the patents were rock solid, but having Browning’s name on them was a good marketing tool, as his designs were already extremely popular with the public.

When Winchester refused the arrangement, Browning went to Remington, who also turned him away. Eventually, Browning approached FN, a deal was struck, and the Auto-5 became the world’s first successful semi-auto shotgun.

While most people recognize Winchester as a lever gun company, the turn of the century saw them becoming a shotgun company.

To remain current in the market, Winchester needed a self-loader, but with Browning’s name on the patents, their design options were limited.

Winchester tasked T.C. Johnson with creating a shotgun to compete with the Auto-5. T.C. Johnson was a reputable designer in his own right and would later create the Model 12 shotgun, lovingly referred to as the “Perfect Repeater,” but his first auto-loading shotgun was a miss.

The Winchester 1911 SL

The gun designed by T.C. Johnson was known as the Winchester 1911 SL — SL standing for self-loading.

Browning’s patents covered a number of particular areas. This included the idea of attaching a charging handle to the bolt, as well as metal buffer rings.

Johnson would remark that it took him nearly 10 years to design an automatic shotgun that would not be an infringement on the Browning gun. Avoiding running afoul of those patents resulted in a gun with a rather interesting set of features.

The most remarkable is the method of charging the gun. The Winchester 1911, like the A5, is a long recoil-operated gun, meaning the barrel moves with the bolt as the weapon cycles.

In order to sidestep the charging handle patent, Winchester checkered the barrel. Users were supposed to grab the barrel and shove it rearward to charge it and load the chamber.

Safety, or Lack Thereof

This creates a rather interesting issue with how to handle the gun. It’s challenging to charge it while keeping it pointed in a safe direction. You have to hold it in an awkward manner, preferably pointing at the ground while pulling the barrel rearward.

Paper shotgun shells of the era were known to swell and cause malfunctions and jams. When swollen, it made it difficult for the user to cycle the action and clear the cartridge.

This supposedly caused instances where shooters would brace the gun against the ground and shove the barrel rearward to unclog the jam, often with the barrel pointed directly upward or at themselves.

Additionally, the Model 1911 SL would occasionally slam fire. I own one and can make it slamfire as the action closes. This occurred to me once by accident, but fortunately, I was practicing good gun safety and was pointing the gun at the berm when it happened.

If I worked the action quickly and violently, it could and would slam fire every so often — maybe once in ten attempts, but that’s way more than I’m comfortable with.

These two flaws, combined with a lapse in user gun safety, proved to be fatal for some, ultimately earning the gun the nickname “Widowmaker.”

Browning’s design used metal buffer rings, while the Winchester had fibrous buffer rings. The weaker rings would eventually wear out, resulting in violent recoil action that was bad enough to split stocks.

Is it All That Bad?

Maybe mine slamfires because it’s 103 years old? Maybe that’s just an issue with the gun’s design. If I had non-worn-out rings, perhaps the action would be so violent.

I can say there is some level of genius involved in designing this shotgun without infringing on only Browning’s A5 patents. The gun also had a few innovative features. For example, it was the first gun to use laminate instead of solid wood.

Additionally, the Winchester 1911 is a take-down model, and the stock separates from the receiver for easy storage.

The controls are okay, but loading it is not easy, and your last round sticks out a bit — the grooves in the carrier lock it in place. It works, but it’s awkward looking, and I thought my gun was broken at first.

It also features a rat tail bolt which was neat to see. It’s a design similar to that of the FN FAL and the Fightlite SCR.

In total, Winchester produced 82,774 guns in 12-, 16-, and 20-gauge. That sounds like a healthy number, but the population of Auto-5 is in the millions, not even counting the various licensed clones by Remington and Savage.

Final Thoughts

Although there were a good few features, the gun failed to find success. Winchester stopped production in 1925 after just 14 years.

These days the Model 1911 SL “Widowmaker” is more of an interesting curiosity in the world of shotguns.

It’s a neat gun in my collection, but admittedly it doesn’t see much use outside of being a conversation piece. Not a gun I’d use for hunting, trap, or skeet, but I enjoy showing fellow gun nerds the more interesting features.
