Sten Mark II Submachine Gun (David Albert Collection)

The intent of this reference page is to become the best single resource for Sten and Sterling information on the internet. It will always remain open to new content. I also want this page to serve as an online reference guide to Sten and Sterling accessories. If you have something you would like to share, please send the description and photos to David Albert at dalbert@sturmgewehr.com, and I will consider it for inclusion.

I've owned a Sten since 1988, and have collected many accessories, including a variety of manuals that I have not seen published elsewhere, and that I believe will be appreciated by the collector community. As far as the Sterling, I only have a basic knowledge, and a couple of manuals, so I will rely upon others to help me with content for that firearm.

The reference page is organized as follows:

1. Sten Submachine Gun Frequently Asked Questions
2. Sten Accessories
3. Sten Helpful Hints
4. Sterling Submachine Gun Frequently Asked Questions
5. Sterling Accessories
6. Sterling Helpful Hints

Sten MK IV

This model of Sten Submachine Gun was apparently limited to prototype only, although rumors exist of its limited use by elite forces. Two different prototype versions exist. Of the various Sten SMG models, the MK IV's appearance differs the most.

Lanchester Submachine Gun

The Lanchester Submachine Gun preceded the Sten in British inventory.  It bares a resemblance to the Lanchester, and can be seen as a simplified version designed for ease of manufacture.

"FrankenStens"

These are not official Sten models...They are modified Stens in the NFA community that I think will be appreciated by those who consult this resource.

Here is a user-friendly Sten that incorporates an FN-FAL pistol grip. It points and shoots nicely.

2. Sten History

Several resources on the internet describe the basic history of the Sten Submachine Gun, including how its name is a combination of acronyms, and that production numbers totaled approximately 3.75 million units. For me, the most fascinating thing about the Sten was how it was born of necessity during some of the darkest hours of British struggle in World War II. If you imagine your country being bombed nightly, along with the truly daunting possibility that an invasion and German occupation could occur at any time...your country is short on weapons and forces sufficient to repel such an invasion...these were the conditions under which the Sten was born. Britain procured as many Thompsons and other weapons from America as possible, but needed more guns of all kinds. Their inbound supply chain was sniped by German submarines, and a generally bleak picture existed around survival. Yet through all this, Britain was able to muster the necessary resources to prevent invasion, and the Sten played an active role in the story. Parts for the Sten were fabricated in many machine shops around the country, providing a decentralized manufacturing base for the weapon that made it less vulnerable to the results of a single, successful German bombing....(More to be added here ASAP)

3. Articles on the Sten

The following magazine articles were written specifically about the Sten Submachine Gun, or featured significant Sten content. Reading articles about the use of a firearm through the years helps provide a "snapshot" in time perspective, and can aid in understanding how certain weapons may have developed a particular reputation. The Sten is no different, and the following articles provide examples of numerous nicknames for the Sten Submachine Gun that developed through use. "Plumber's Delight," and "Cake Decorator" are two that jumped out at me.

1. Sten Manuals


The Sten Submachine Gun has seen service throughout the world, and several uncommonly encountered manuals exist documenting its service. There are multiple versions of British and Canadian manuals, to include commercial WWII Home Guard examples. Sten manuals from The Netherlands, Belgium, Norway, France, and Israel also exist.

Dutch Sten Manual, 1943

The two Dutch manuals are very interesting to me, in that they are designated as being for the "Sten Model IV," but do not show that weapon, which was probably never used in any number. In the first Dutch manual, shown below, are drawings of the Sten MK III.

Mk2 Adjustable Sten Sling (Roscoe Turner Collection)

Two slings exist that were specifically designed for the Sten Submachine Gun. The first was a non-adjustable type, and the second sling, designated "Mk2," features a buckle to allow length adjustment. The non-adjustable sling was requisitioned via Catalog No. BE 8574, and the later, adjustable sling was requisitioned via Catalog No. BE 8604. Many examples are marked with their catalog numbers. Both slings are approximately 3/4" wide. A variety of manufacturers produced Sten SMG slings during WWII. Most Sten slings feature manufacturer marks with dates ranging from 1942 to 1945.

Most Sten slings are encountered with a round metal loop that attaches to a barrel shroud cooling hole. In the case of some Sten slings manufactured in India, the round metal loop was made with a blunted nail. Instead of the metal loop, some slings have a spring loaded clip.

Some observed manufacturer marks and dates include:

Some Sten slings do not have manufacturer markings. The Enfield Rifle sling was also used in combination with an early, skeletonized Sten stock that featured a diagonal metal piece within the wrist of the stock, where the Enfield sling could be attached.

One Sten sling in my collection is painted, and the paint appears to be rubberized. If anyone has further information on this feature, please post it in the forum, or contact me at dalbert@sturmgewehr.com. At this point, I'll make the assumption that the sling may have been used in the tropics, and the paint was applied to aid in preservation and longevity in such climates.

3. Sten Web Gear

US M3 Submachine Gun Triple Magazine Pouch Rigger Modified for Sten Magazines:

Here's something you probably haven't seen before...I know I hadn't. This item has been in a collection for some time, and recently, the origin of the pouch was determined. These M3 SMG pouches were rigger modified for silenced Stens used by U.S. Special Forces in VietNam. The weapons were apparently used primarily for ambushes, and the fellow who provided their identification served with the Special Forces in Pleiku in II Corps in the Central Highlands 1968-69. The slight rust markings on the fabric match up to the Sten magazines perfectly.

4. Sten Magazine Loaders

If ever there were a firearm that needed magazine loading tools, the Sten is the one! Trying to put the last 12 rounds into a Sten magazine without a loading tool is a frustrating exercise that will surely reduce your time on the range, and increase your ibuprofen dosage.

At least 3 different Sten magazine loader designs exist, each having their own unique method of making the loading task easier.

Pictured below is a British Sten Magazine Loader, of steel and brass construction. This seems to be the most commonly encountered design, and its official designation is "Filler, Magazine, 9mm Machine Carbine, Mk2," which was requisitioned via Catalog No. BE 8322. It is not the most intuitive device, so the following pictures are offered to help with instruction on this subject.
http://www.sturmgewehr.com/dalbert/MGBoards/StenLoader1.JPG

The loader is placed on top of a Sten magazine. It only fits one way, and has a piece of spring steel with a detent that holds it on the magazine.
http://www.sturmgewehr.com/dalbert/MGBoards/StenLoader2.JPG

The brass piece is pulled down with a finger to depress the magazine spring, and presents an opening into which a cartridge is inserted.
http://www.sturmgewehr.com/dalbert/MGBoards/StenLoader3.JPG

The brass piece is then lifted, and starts to push the cartridge into the opening in the magazine.
http://www.sturmgewehr.com/dalbert/MGBoards/StenLoader4.JPG

The brass piece is lifted to full height, and the cartridge becomes fully seated into the magazine.
http://www.sturmgewehr.com/dalbert/MGBoards/StenLoader5.JPG

The process is repeated, depressing the previous cartridge down into the magazine, while presenting the opportunity to load another cartridge, until the magazine is full.
http://www.sturmgewehr.com/dalbert/MGBoards/StenLoader6.JPG
Above images by David Albert

Here is another style of Sten magazine loader, officially known as "Filler, Magazine, 9mm Machine Carbine, Mk4." It attaches to the back of the magazine, with a small finger that holds under the lip of the back of the squared portion of the magazine top, and a spring tab that locks into the magazine locking slot. The lever is manipulated, pushing down the top cartridge, until there is sufficient room to insert another cartridge.

5. Sten Cleaning Rods

The Sten cleaning rod pictured below fits into certain Sten MKII skeleton stocks that feature holding tabs riveted inside the frame. The cleaning rod fits the contour of the stock.

7. Sten Ejection Opening Guard

The "Guard, Ejection Opening" is a spring steel device that attaches to the Sten barrel shroud, and physically blocks the hand from sliding backwards over the ejection opening. The example pictured below is a Canadian version of the device, and is marked with a broad arrow inside of a "C."

8. Sten Bayonets

Original Sten bayonets are quite rare, since their utility was apparently questioned, and most were scrapped. A well known vendor sells a reproduction of the bayonet, and anyone considering the purchase of what is stated as an original should remain very cautious.

This tool fits into the 9mm Sten cartridge chamber when a case becomes ruptured, and is squeezed to grip the remaining brass piece, and remove it from the chamber. The tool is unmarked.

MK2 – part number B3/CR 677. With the repositioning of the tripping level 1.3 inches forward to accommodate the pistol grip of the MK5 Sten a larger recess was milled along with additional cuts under the breech face. Differences in the milling near the breech face are circled.

4. Checking Ammo for Functionality/Sear Engagement

It's a very good idea when firing a Sten to check if the ammunition you plan to use will operate the weapon as designed. I have personally experienced placing a 32-round magazine in my Sten, and when I attempted to fire a short burst, I ended up with a 32-round burst. The ammunition I was using was powerful enough to cycle the action, however it did not push the bolt back with enough force to engage the sear, so it continued to fire until empty. It is recommended to place only a few rounds in the magazine to test the ammo to see if it cycles with enough force to engage the sear, and allow trigger control, and then to proceed to full magazines, observing all appropriate safety precautions, of course.

An attribute claimed for the Sten was that it could use any 9mm Luger ammunition. While this is true, based on chamber dimensions, etc, for best performance, its not quite that simple. Stens require quality ammunition, with strong cartridge cases. The combination of advanced primer ignition, coupled with the 360 degree cone in the breech of the barrel can produce ruptures if cases are on the thin side. A ruptured case will probably produce a stoppage, which can frequently be cleared. The problem is, the bullet can lodge in the barrel, creating an obstruction, and potential for a mishap. When the gun is subsequently fired, the barrel may be bulged or burst. It wasn't until the Mk. II cartridge was established that this problem was significantly reduced. A burst cartridge case will get your attention, and appropriate safety precautions should be taken whenever firing a Sten to reduce potential for injury.
