I've been doing the same with my wife, except my chosen home defense is the FN PS90. The 5.7 ballistic tips are not going to go through many sheets of sheetrock before stopping, there is hardly no kick, and she or I can put 50 rounds on target in an extremely short amount of time. The 'room clearing' ability of a shotgun is a myth. Shotgun for defense is best employed as a medium range firearm, such as wife covering you as you say hi to people at cabin for first time.
