I've been inspired by recent threads here, posts on FB, my own shotgun classes I teach, and several people I know making great stuff for shotguns, to start this thread in the same vein as the AK thread.
The fighting shotgun circa 2017 is a greatly upgraded beast compared to the basic bitch pump gun one can buy at Wal-Mart for $350... not that there's anything wrong with those.
Let's discuss the current state of the art regarding the guns, ammo, accessories, and employment methods.
Are these beasts on the brink of extinction? Or are they entering a new Golden Age?
Please make your context clear when referring to military, LE, PMC, or private security use vs. civilian applications.
