STEN and mag go gauge

[Peter Laidler]

Like I said earlier. Like everyone else in the world who owns a Sten gun, you have a one man dog so just get 10 magazines the feed and function with YOUR gun!
Another thing is that YOUR gun was made to shoot UK Military standard 9mm round nose ammo. Just ike your MGB was made to run on super'X' octane petrol.
I don't have mags in front of me to compare BUT I don't think that the mag shown in photo 4(left) is from a Sten
As for those opinions about the mag opening measurements, well....... All I say is those immortal words '.......in my limited experience of these things....' and leave it there. There are real experts out there of course and I readily accept that.

I have seen Sterling magazines adapted for use in a Sten and they seemed to function perfectly. It has to be said that Harold Turpin was not happy with the magazine design from the word go, But he was told to use the Lanchester magazines that were already in production due to cost and time considerations*. Even then he (so said by his daughter who was Reginald Shepherds secretary.....) threw his teddy in the corner and came up with the shorter magazines. Not the answer but better than the long magazines he had to do his initial tests with.

Feeding a Sten........ Use 10 mags that work with your gun and use the ammo that it was made to use. Lips to be parallel with an angle of presentation of 8 degrees. This presents the tip of the nose INTO the chamber. If that happens, all is well

* don't forget, he only had £5 to spend to develop the gun.
