If one is concerned about being awoke and not being "awake" enough to handle any firearm confidently maybe they should rethink their entire defensive plan while at home?
I'm not getting into specifics, but adding hinges to doors, adding locking devices that secure the top and bottom of the door to the floor and wall, installing reinforced door frames and using solid doors, "hurricane" window film on glass, multiple home security systems and if one is so inclined a yapping dog are good places to start.
My "bedroom" guns are an AR pistol and a Beretta 92.
Both are equipped with lights and are fully loaded with one in the chamber and the safeties on.
Neither are sitting right next to my bed or under my pillow (ugh...).
The AR is behind my bedroom door which requires me to get out of bed and to walk a dozen of so steps to retrieve it.
The Beretta is on top of the dresser, un-holstered also about a dozen steps away.
My home is secure enough that if I'm startled awake because I hear someone in my hallway outside my bedroom while still in bed this means all my other measures have somehow failed and if this is the case I'm probably outgunned and already a goner.
May I suggest that some of you guys look into security measures that will alert you well before you are startled awake?
