8 round mag in PM9?

[lwj]

I have leftover 8 round mag from P9 and would like to use it as a spare in PM9. It looks like it should work OK.
Anybody tried this combination?
Is there a filler that would go between the grip and the mag base?

Works fine. Dont think theres a filler though. Works, but looks weird.
