Scubie, DrJason and I attended a "demonstration" of the benefits of this weapon system.
I can't speak for either of my viewing partners. They may love the model.
I think this is a weapon "solution" looking for a problem to call home.
PLUS: You can load a six pack of two different shell types.
MINUS: In the heat of combat you have a selector switch for two different shell types.
For me? I find the giant lower dual shell tube as a detriment to rapid follow up shots.
It's a pump action, so you have to rack the weapon, which takes time and it's not semi-seamless action that a semi auto brings to the table.
Now take this with a grain of salt. I have what I consider to be the best shotgun for my needs. Period.
While this shotgun is inventive, I don't personally find it as "awesome" as some do. That doesn't take away from what it brings to the table, but I don't personally believe it is as "inventive" as it's being touted as being.
If you buy one, I would LOVE to see a Range Report.
