I love my S9. I've had nothing but accuracy and reliability... compared to the A1, the older S9 is nicer for those with small-medium hands, and also better for concealed carry due to the rounded profile (specifically the lack of a standard rail) being less likely to hang up on something. One word of caution is to watch out the first few times you take it out (if you're getting a new pistol) because the loaded chamber indicator needs some breakin, and until about 500 rounds are down the tube it will occasionally throw an empty casing at your forehead. Dry fire the hell out of it - the trigger only gets nicer, and you won't break anything. If you get a non-A1, the trigger may be on the heavier side (8 lbs), but SAI will upgrade it for free (less shipping) if you elect to have it done (I passed since the trigger's not all that heavy, and breaks nice and clean as it is). Whoever sells theirs doesn't know what they're missing out on.
