I hold one finger the rear side of the mag lip thing and then use the speed loader diagonal into it from the other direction.

Through I tend to just use the loading tube thing that comes with it now, speed load into that then just slide the thing down

The King Arms speed loaders come with an adaptor to let you load pistol mags.

Just use the pistol adaptor, it's a piece of piss then.

I got a pistol speed loader with an adaptor specifically for these mags, it is useless though :/ I seem to be getting it in fairly easily now - thanks for the tips.
