Muzzle Braked Shotgun

My online friend, Steve, over at The Firearm Blog, recently had a post about a new Mossberg scattergun. The gun is interesting, what is exciting was the illustration that went along with it: clicky to embiggen



Here is the photo of the shotgun:

I'm not a huge fan of Mossberg shotguns, however, it seems like an excellent marketing ploy to suck in both pirates and ninjas.
In a past lifetime I had to pleasure of insert proper adjective here: use, train, borrow, rock, pull the trigger on, a 14" ported barrel 870, there was nothing faster/ I could put five full power slugs on target in about 2 seconds. I have been debating porting or braking my home defense 870. More to follow on that later.
