As for fav shotguns:
I just picked up a Benelli a police trade in, I have fired one a few times at the range and a scout had one when I was their primary weapons guru for their merit badge. The shotgun was 12 gauge, it was the short home defense version, this thing was still almost bigger than the kid using it.
A sweet system! And honestly it is the only semi auto shotty I have used in earnest, and would endorse as one I would carry in harms way. I have fired the SPAS, but it was so long ago, I just don't remember. A good system but that is all I remember.
Although for game purposes, the idea of a character having a Browning auto is a tempting idea for a characters primary personal weapon. After all a shotty is much better at close range than a pistol and much more forgiving when it comes to pressure shooting and aim or lack of aim
PS Paul, you can petition to have the restriction overturned so you can utilize hardware again.
