MP40 or Vigneron magazines in a Lanchester

Pete, I agree, I have to admit to not reading/ seeing any 'material' OFFICIALY published on the topic of german Mag interchangability.

It's just that, I have personally used them in Stens. Talked to Vets who did. & read 'Somewhere' accounts of this happening, during the war.

I was therefore, under the impression that this was a small feature of the Stens original design.
But it would seem, like it was a 'Bonus' of the interface mag design?

Captured ammo was most Certainly used in Stens on occasions, as you know. & TBH, it would make perfect sense, for a Crunchie to pick up a full MP.40 mag. & Try one in His Sten!
if it fitted & fired alright. Then that would spread like wildfire, Yes?..

I'm sure that in a particular given situation. The Mag exchange scenario may very well have saved a Crunchies Life!...

Regarding Vignaron Mags. I have encountered quite a difference in Tollerances with them! Some will fit in & fire, some will not. This is also a MUCH bigger problem with Vig Mags in an MP.40! I have in my own collection, an MP.40. That even an original MP.40 mag will not go right in the mag well!!
Another original mag will!......So for ALL in the SMG class of weapon. Tollerance has a BIG part to play!

trying & fitting a number of DIFFERENT Mags. Of Differeing Weapons, may well surprise you. As to what will fit, & what wont!.......Peter will concur with that one!
