Probably a dumb question about the PS90.

Might be picking one up soon. I was just wondering because they come in different magazine/clip (sorry dont kill me) sizes. If say I were to order this one https://www.sportsmans.com/shooting-gear-gun-supplies/modern-sporting-rifles/fn-ps90-57x28mm-16in-black-semi-automatic-modern-sporting-rifle-101-rounds/p/1457600 can I buy a 30 or 50 round magazine for it? I'd assume all PS90 mags are the same dimensions, ya?

Thanks.
