Have you considered a S&W Shield? Mine is accurate and though I have never had experience with any of the guns you have mentioned I have read that the Shield is a softer shooter, less snappy, than most of the other pistols. They are thin and are easy to conceal but capacity may be a problem for you. Mine has a capacity of 8+1 but MagGuts makes a magazine spring that increases the capacity by 1 or 9+1. With the Shield you could buy several extra 8 round mags and conversion kits and still be well under your budget. I think it all comes down to what you are most comfortable with. Hold all the different guns and if possible shoot them then buy the one that fits you.
