This is my one off, HK imported Benelli M3 Super 90 "Pest Control Matrix"
It does fire "Rifled" Slugs
Just installed a modified Mesa Tactical M2 Shell holder with Picatinny rail, had to modify it to allow the pump action clearance on the left side...still needs to be Cerakoted.
Have a ITT flashlight mount coming to mount a surefire x300 on the mag tube, and then she'll be ready to go.
