Hiya!
I have one of the aforementioned monsters. (Pre-ban, all the "nasty" whistles)
Persoanlly, I'd grab one of my 870s or 590s before relying on the SPAS.
Mine's never been fired (like many of my other nifty weapons that have been totally outlawed in the cranky state of NJ)
One thing that hasn't been mentioned is that Franchi issued a recall soon after (1 year?) offering the weapon for sale to the public. Something about the possibility of a round being discharged while chambering a round. They offered to replace (the horrendous) safety and supposedly that would solve the problem.
I never sent mine back, so now it's a scary conversation piece.
