I love shotguns. I always have and I come from a family who used shotguns for hunting deer, shooting birds, and defending the homestead. In the Marines, I was one of the few Marines issued a Mossberg because I could not only use, but teach the shotgun.
To me, shotguns are constant experiments in ammunition, sighting systems, and usability. By the bedside sits a Mossberg 590 similar to my issued gun way back when I was cool.
