I emailed Benelli nobody can confirm this. Anyway I'll have to wait for their reply if ever. Thanks

Hello guys, I've been reading everybody's post about the benelli M4. I'm about to take the plunge and purchase the M4. I plan to use my Salvo 12 with the new Benelli M4, which model should I buy that I can install my Salvo 12 suppressor?
