Your problem was the DISCO @$$ pistol grip. Under stress practically no one can hit with one and the recoil becomes uncontrollable
So I found L0L! As I said earlier, I like the shortened Shotgun in close confines, But with those loads its uncontrollable and likely to maim the shooter.
I just wanted those that recommend shotguns(and I'm one of em) To inform Newbies as to some of the things experienced shotgunners take for granted
