There are a few folks on here who know, have experienced and understand the advantages and limitations of a shotgun for an offensive/defensive firearm choice. I believe you to be one of those folks and I can spot those who aren't from a mile away....it is usually good for a laugh though.
Stop it; you're making me blush! I'm not very experienced but I have at least patterned my HD gun at realistic distances and have done some practice and competition. That and I've got the Magpul video so I guess I'm close enough to an expert for the 'net!
