The DAO pocket 9's are great guns. It takes a little practice but they can be pretty accurate. I actually can shoot accurately faster with my LC9 than my 642 revolver. First shot is about the same but the follow up is more accurate with the 9. The 642 is a little more comfortable to carry, it's a little lighter.
You will need trigger time with a DAO whether it's a revolver or semi. It'll never be as easy to shoot as a good 1911 or 92FS.
