I can't imagine how off the balance is on that thing. I've had quite a few extended magazine shotguns, and always found them "nose heavy" and "hard to get on point quick".
As a result, my Benelli M1 Super 90 has a 1 round extension.
If I need more "firepower" I won't be grabbing a shotgun...it'll be my FN SCAR.
My shotgun is for home defense against the meth-addict looking for drug money or the coyote looking at my chickens. For anything else I'm grabbing either my 5.56 or 7.62 FN Scar.
(Yes, I have both calibers and they are awesome).
Actually Its not bad at all ballence wise. I used it for trap shooting tuesday my first time shooting at a moving target with a shootgun and managed to hit 7 out of 25, I considered it pretty good.
Yep 5.56 and 7.62 are great med to long range rounds but if I am moping up an infestasion in a building I will take a shotgun any day of the week.
