I moved out of the city a couple years ago, but I used to answer the door armed, yes. I'm in a more rural area now and between large dogs and weapons always close by, I usually don't now unless I'm already carrying. I conceal carry away from home and open carry at home, but it varies when coming to the door at home these days. I live in a gated community and most of my neighbors are gun enthusiasts... many able to legally own and use suppressors, SBRs, and machine guns.
Texas... the greatest nation on Earth.
