I've always been really surprised no-one put any serious work into turning the Ishapore .410 shotguns into repeaters, especially in Australiaicon after the 1997 arms law changes. Surely it wouldn't be impractical for a gunsmith to design and have legally manufactured a magazine which would fit the guns and function effectively?

Then again, I'm not aware of anyone making functional magazines for the .22 No 2 Mk IV trainers either, and that's always struck me as another obvious candidate for such an endeavour.
