A couple things I gotta say about this -
I like the AMD front-pistol grip idea on the shotgun - very interesting idea.
This would have extremely limited application in the LE world. Tactical entry, etc. must always consider collateral damage like the passed-out crack whore bent over the sofa in the same room as the dope pusher they are trying to arrest. "oops I shot the crack whore while shooting at the dope pusher" is a bad thing for LE public image. Then again, military could probably find use in this when raiding things like Osama Tunnels in Afghanistan. Which brings me to my next point -
No GUN CONTROL here - that big fella could barely keep the shots on the side of a MINI VAN so I know a skinny little guy like me is going to be throwing lead all over the street in front of the bank. If a horde of commie bastard zombies were coming my way, OK, but *DARN* that looks like an unweildy weapon. And I thought my SPAS-12 was unweildy!!!!

Needs a muzzle brake to be sure. This is one application where I can see a huge unweildy (and HEAVY) weapon making more sense. Thus the USAS-12 could be a better solution, IMO. Semi-auto to be sure, but possibly a better solution.
Since this is for LE/Military, they need to make a spiral-wind 25 round drum for that sucker, ala USAS-12 drum mags. Now THAT would be a crowd pleaser.
I would choose slugs for most situations. IMO that would be the best solution with this type of weapon. FA 12-gauge slugs (even saboted slugs) would provide enough lead downrange. I know, I know, ammo selection is an age-old argument where everyone is wrong and everyone is right so I don't expect anyone to agree w/ this point.
What's up with the teddy bear? They have issues with cute cuddly animals?
