Hi,
Lost track of you, hope all is well.
Talked to my folks at Benelli today, no help from the factory. Brownells lists 2 mag extensions for Nova.
PN - 149000025 2rd extension Chote
PN - 867000014 2rd extension Tacstar
I DO NOT have any experience with these products. Did not like the Tacstar extension for the mossy.
No help on a different length barrel.
Good Luck & Be Safe
