[Nova/Super Nova polymer]

Anyone know what kind of polymer is used in the receivers of the Nova and Super Nova? I.e. Zytel or something along those lines?

Does anyone know if the Super Nova will eventually replace the Nova entirely, or will the two continue to be marketed together?

[New to Benelli]

I'm thinking of buying either a Nova or Supernova in the home defense version (shortened barrel, black finish).

 

As I understand it, the Supernova is an improved Nova. What are the basic differences between the two, and would one be more suitable for home defense than the other?
