While i totally agree with you as to the efficacy of the 45, if in a home defense situation, i'd prefer a tactical shotgun (although it doesn't fit under a pillow very well)
Funny thing
Years ago I tried sleeping with a gun under my pillow
Never worked
All night I stayed awake thinking about
What if I have a dream and reach for the gun
So I put it in my nightstand
Then i thought
Well what if I have a dream and reach into the nightstand
Then I thought about it
and figured
You know what. If someone makes it to the bedroom it's allready too late
So now what I got is on the bedroom door
You can have anything you want on the first floor
It's all yours
Start coming up the stairs though and it's game over
