I hear ya.. I’ve heard that the Italian-made Benelli Supernova is pricey but a slick piece.. Sounds like the Mossberg’s have more aftermarket goodie attachments though. I would recommend to any buyer to check out the scores of videos on YouTube, save to mention that they are fun to watch!
Or, if that is all you are packing, it is short enough for CQB/room clearing and getting into/out of vehicles.
And, as you said, they have a wealth of after market goodies available to them because of their popularity. When I picked up mine, one was $305 and the other was $290 and both came standard with the heat shield. Also, for situations like breaches/CQB you're less likely to get a jam or a feeding issue than with the semi-autos.
