Loose Magazine on Denix MP40

[Kameraden]

I just got a Denix MP40 and am happy with it overall.
However the only thing I don't like is the magazine rattles a bit unless you are holding it in the shooting position.

I would imagine on a real one the loading/shooting mechanism locks the magazine firmly in place. However with no such mechanism to do this it rattles a bit.

Anyone have any tips to stop the rattle without being too visible?

Thanks

Add some tape or the soft side of a velcro strip to the mag-well.
