I have a Glock 29 + extra mag in an IWB holster at ALL given times when I am OUTSIDE of the house. Inside the house, the possibilities are endless. When I am naked in the bathroom, anything from a Kel Tec P-11 to a Ruger Super Redhawk .454 Casull could be sitting in the drawer next to the sink. When I am sleeping there is a pistol approximately 2 feet away from my shoulder, some sort of long gun within 2 steps and 2 sets of level III body armor + a level V trauma plate hanging on my closet door which I think is about 2 steps away as well.
There is no such thing as a "routine walk outside." Every place on this Earth can present a deadly threat at any given time, even IN YOUR OWN HOME. BE ALERT.
