Didn't you just start two threads about this that got closed?
I't may be your opinion but experts will disagree with you. I personally think they are a joke and there only practical use is loading it up with snake shot for woods carry.
One need only look at the shooting that took place in NYC's Empire state building ,the cops were using a well made and well designed handgun,shots were missed and people got hurt.
If they were using shot shells far more people would have been inured from missed shots.
