I'm a big fan of the tiny terror ... I routinely carry my NAA Pug on dog-walking ventures in my peaceful neighborhood and am planning on gifting myself post-Christmas with a Smith 351PD ... it's an extremely useful round, accurate and hard-hitting ... I don't think I'd count on it as my primary weapon, but it's great for fending off the occasional skunk or rattler (don't see them much in my part of Texas, but I have seen them). My biggest ownership mistake was selling my Taurus .22WMR revolver some years ago to help finance the purchase of a gun I had to have at the time ...
"The gun has been called the great equalizer ... It insures that the people are the equal of their government whenever that government forgets that it is servant and not master of the governed." --Ronald Reagan
