Whirlibird, I find it interesting the talk with the SWAT officers since I live in the middle of a City. I own two 22lr rifles, one 9mm handgun, and two shotguns because of the City. In a SHTF that is what I would use. I also own a .308 but that is for hunting. Because I live in the City I also own other handguns like a small .380 and a .357, but the 9mm will be every were in a SHTF.
