Interesting Wartime article on the STEN.

Can anyone verify this statement in the article: "But in order to prevent the enemy using captured British ammunition, they designed the rim of the cartridge that it cannot be gripped and ejected by the extractor of the German gun." Or was this placed in the article so German agents would read it and past the information on to Germany where a directive would be sent out from Wehrmacht HQ telling the troops that British 9 mm ammunition is defective and cannot and will not be used in German weapons.

Over 30 years ago I fired several hundred rounds of WWII Sten gun ammo through a MP40 without incident. The headstamps were clearly marked with wartime dates and the asterisk.
 
A Sten will function with its extractor removed. Better with it installed.
I suspect that the business about ammunition compatibility is a bit of bumpff.
Sten parts production was extremely diversified. But final assembly occurred in large facilities - ROF Enfield, BSA, ROF Theale. I suspect a bit more disinformation.
Yes indeed it will fire, till it does not. Then tell me just how your going to "extract" that unfired and dead 9mm round now working as a chamber plug??
While the canulares of the German and Commonwealth 9mm is different and the beak of the Sten extractor is different in dimension from a MP40 (I checked that myth out years ago) the "issue" of interchangeability between what ammo goes in what gun is hardly a war winning/loser.

Without an extractor, ejection is on the weak side. Tried this years ago. In the event of a misfire, it would be necessary to #### the gun, and shake the round out. In an open bolt gun, in theory there is no reason for a round to be stationary in the chamber.
The Gevarm .22 does not have an extractor.

Well it may rattle out, or it may not. You mention that there is no reason for a round to be stationary in a open bolt gun, trust me I get it and been around lots of open bolt SMGs. What I am saying is if the round fails to fire and is well shoved home (chambered) by the bolt one may get lucky and shake it out but I think the extractor, extracting is the ticket.
 
According to Shepherd, quoted in Laidler's Sten Machine Carbine, it was ENgland.

Well, that IS interesting.
I was sure about the ENfield connection, but if Shepherd himself says otherwise, I'm inclined to listen.
I'm not the only one to have believed the Enfield story. :)

I know the mechanics of the auto STEN - has anyone encountered the drawings for a semi? Semis are usually a tad more complex, I'd like to see how they tackled it.

There are drawings and kits available in the states. Some ###### kind of screwed up the semi sten world in canada. Apparently the RCMP revoked the frt because if it. I don't think it would be an issue for Non restricted closed bolt, but I'm waiting to find out...
 
Yep, and he has been banned about 30 times here on CGN.
And he will be along again, and banned soon after...

they don't need a extractor the cartridge case will ride with the bolt backwards until it hits the ejector(this is welded into the receiver tube) PA luty's homebuilt smg's to have a extractor either
 
The point being raised is that without an extractor, clearing a stoppage may be problematic.
In any blowback gun, the spent case is going to come out of the chamber. The extractor may contribute to positive ejection by providing a pivot point, and will certainly help if there is a stuck round.
The Luty design is interesting, from the standpoint of doing something starting with almost nothing - but it is hardly something to be held up as an example to be emulated.

Tiriaq gets what I am going on about the need for a extractor. The Sten (of which I own, live CA) and all other open bolt SMGs can work well enough without a extractor, till the one day (and this always seems to happen at the worst moment) a round fails to fire. That's when your going to REALLY wish you had a extractor with a nice crisp beak to claw that dead round out of the chamber.
Even the drill for removing a chambered unfired round from the C1 SMG was to use the sling to snap the bolt back to get a unfired round out. I recall one time we had to lay the gun on the gun (facing downrange) on fire and kick the cocking handle with the heel of a combat boot to extract the unfired round.
 
Another way is to punch the cocking handle against a post or some such. At least it can be pointed in a safe direction, with no body parts in front.
Similarly if an autoloading pistol is locked shut by a stuck round, don't try to pull the slide back - hold the slide firmly, and drive the shooting hand into the grip, hard.

no different than using your sling and boots on a C7 or C9 cocking handle when it won't open.
 
I liked the term "People's Gun" in the article.

Every nation has come up with such a gun under wartime urgency - the Aussie Owen, the Russian PPS 43, etc. Cheap, easily produced without a lot of machining.

I think I know what I'd do if I had a round stuck in the chamber. It's called a cleaning rod or dowel.

id a knife would be easier its normally right there and it would be a easy grab i usually have a cheap folding knife handy that has the tip ground flat it would grab the rim of a 9mm easy enough
 
I fired a Sten full auto at a machine gun shoot in New Hampshire 20 years ago.Quite the experience I gave it a little squirt and let go of the trigger and it fired a couple more rounds I guess it was wore out.

One of three things or a combination of them could have had a couple go down range unintended. Worn sear, worn bent on bolt or subpar ammo.
