Stoeger M3020 v Benelli M2?

[JH1961]

New to the forum, but not Benellis. I owned several as an LEO: M121, M1 Super90,  and now, years later,  an M2 20ga field gun. I also have a Stoeger M3020 Tactical, also in 20ga.

I am told that some (?) parts interchangeabiloty exists between them. So... Is anyone aware of a +2 or +3 magazine extension for a 20ga M2 that will fit my M3020?

Thanks in advance.
