SHTF, it may be complete government collapse, outside invasion, natural disaster or what ever. In many cases besides invasion/combat a pistol would be my choice, even for CQC I would chose a pistol. Its easy to hide, easy to holster if performing work, rescue, etc. A high cap 9mm, 4 extra mags is my choice. I can carry it every day, because in most cases I dont want to have to fight my way to my house to get my rifle, I want to meet my family in a safe place and not worry about getting back to my house. Having a long gun in a safe place is not a bad idea, but not my first concern.
