The R9 is made for concealed carry. It is not for times when the fit hits the shan, as they say. When that happens, who cares about being able to carry concealed? Strap a big Sig, Glock, or 1911 on your side and carry an SKS or AK.
"We are one power outage away from the Stone Age. One week of no electricity and your neighborhoods will be in total anarcy. Personally I don't think I want to be around when that happens."
A personal note on this. Having just lived through Hurricane Ike and being without power for 12 days, it's not like that at all. In fact, it was a very rewarding experience. Everybody hung out together, all the kids and parents played together on the street, people shared food, batteries, water, etc. Nobody had to go to work, so we all had time to just clean-up from the storm, help each other out, and just be normal people. It really felt like we were in a small town, instead of the big city. I really think it would take an awful lot to cause the kind of anarchy you're imagining in your head, and even then people would tend to stick together in self-defined groups and would not be "lone wolfs".
