I alternate between several guns but they all operate the same way - DAO. On-duty I carry a Beretta MiniCougar 8000D 9mm, my current BUG is a Kel-tec P3AT. Off-duty is usually a Kahr CW9, although I sometimes carry the Beretta or the Kel-tec. I just purchased a S&W 360 .38spl that I'm having rechambered to 9mm that will be my new bug, the hammer will be bobbed, so it will also (for all intents and purposes) be DAO like the others.
