Excellent question Buckley!
This debate has been known to go on and on. This is in my own opinion. I have my pistol not on the night-stand. But hidden within easy arm reach. I do not want someone breaking in, me not knowing and getting to my pistol before I wake.
I will use and reach for my pistol first. Easier to manuever through-out the house.. At least my house. Harder to grab, and a greater capacity. The wife on the other hand will grab the shotgun filled with #00B and 5 on the sleeve. Rack to play.
There is one other thing that will happen that I dont really share. But when she ducks points and rack, if the "perp" does not exit the premises, I will "search" and attempt to "destroy". She then takes cover with shotty in hand and knows what to do ( I do not want anything to happen to her under any circumstances so she gets the shotgun).
A shotgun in a "controlled" area of not a lot of "stretch" room is more effective than a pistol)
Now IMO I will not get the shotgun if this fight happens to be taken outside. (Legally being able, fear of safety comes into play, so chances are I will fight to the end). Less range with a shotgun and more chance of improper destruction to something not intended for.
I go through different a scenerio, and the best course of action IMO each and every night with the wife. I go through the house when I have gotten home and have time, each day, to physically go through the "played out" scenerio, and try to find a better solution. Now the best thing that I can recommend is to do what you feel is best IYO and what you are most comfortable with.
Whether you think you can, or cant... You are RIGHT!!
