Man I am really liking this pistol platform. The ability to swap out from 9mm to .45 without more FFL paper work sold me on the idea . You can also go from a compact to a sub compact to a full size just by ordering the parts directly from Sig . The DAO is very smooth and has a better trigger than my trusty Beretta 92Vertec. Iwill try it out at IDPA this weekend and see how I do. All of the parts to covert are not available yet but will be soon. Link explaining the system .
