Which is why I say that a smallbore defensive shotgun is a good idea.
All members of a family unit that can shoulder a longarm can put it to good use.
The Federal 3-inch #4 Buck with a Mossberg 500E in the fullchoke or cylinder choke config. will do the user very well at inside the house ranges as long as said user does their part.
yet a few gave me the stink eye for mentioning it in the shotgun thread.
