You are absolutely correct! I believe shotguns are a specialty weapon that require extra training to run competently in today's world. Of course they have been used successfully countless times in your average 0.001% home defense case as would anything in the hands of a determined defender. But we are all talking about higher level competent trained defense here and I think shotguns present more needs on top of rifle training.
However if you need the few advantages a shotgun provides, they are worth the extra work.
