As the situation dictates...My home defense handgun is there to give me a chance, and an opportunity, to get to said shotgun with 00 buck loaded up...
There is no reason to sweat the "legal" jeapardies in regards to what you use to defend yourself in your own home...
It used to be people did that with a baseball bat...Until the BeeGees came in with knives...Then people started using handguns, when the BeeGees came in with their own cheap guns...And so on and so on...
I only see this as a problem for the bad guys...
