I have a Benelli M1 Super 90 Tactical, and sold my H&K M1 Super90 to a close friend. The best tactical/defence shotgun out there. Check out the 3 gun match shooters, and you will see that 98% of them use a Benelli shotgun. I wouldn't ever sell mine! My favorite long arm, and I have a bunch of AR's. Jump at the opportunity if the price is right.
I changed the Tactical to a straight stock, as I can reload much faster that way. The pistol grip shotgun is an early H&K imported Benelli.
