P90 9mm magazine conversion?

[dakota.potts]

I have kind of a crazy idea for a top loader project and a FN P90 style magazine is the best I can come up with. Anybody know if these can be converted to 9mm? What would be the challenges? Hoping to get some info without having to buy one

I know I love the ergonomics of the PS90 (except the trigger pull), I would go nuts for a PS90 in 9mm! I am a sucker for subguns in 9mm. I know this has nothing to do with your question but, dang you, for making the gears turn.

Let me know if you find out if the magazine can be converted

I may have to buy one to play around with when I catch up on my other projects. It's not for use in a PS90 but in a mockup for a custom build
