shotgun yes. and pistol too. but since you weren't wearing pants to tuck it in, I guess shotgun only was ok... sigh...
Since you mention the spread of the Shotty, here is a target from ~10yards with defensive 3" load (I even shot this one handed to see what it felt like...felt like a .500 Smith long barrel revolver)
Surprisingly, with 2 hands and 2 3/4" Buckshot it isn't unmanageable...everyone that has shot it says it's easier to handle than expected...
That's at 10yds? That is insanely spread out for 00 Buck at 10yds. What is the length of that barrel and what ammo are you using? I've patterned 18" shotguns with several rounds of ammo and never come close to that. Those NFA SMS/AOW shorties just earned a lot more respect in my book.
So here's my question:
If a would be intruder is not actually in your home, and you go outside to seek him/her/it out, gun in hand, are you not brandishing at the very least? This is just a legal question.
Since I have 320' distances in my house I usually go for the rpg.
