709 is my EDC. Just a suggestion based on my own personal experience... get the one with the stainless slide if you can. The bluing is very thin, and I stripped off a lot of the finish cleaning it after a hot sweaty day this past summer. I sweated through the leather holster, and found the right side of the slide (I'm a lefty, worn IWB, so it was the body contact side) covered in rust.
Cosmetically, they leave something to be desired. Sights aren't great, but aren't horrible, either. Bluing is thin and will rust quickly in the right environment.
Conceals extremely well for a 9mm. Accurate enough inside 10 yards, gets sketchy for me outside that. Never had a malfunction, though. Feeds and fires everything I've put through it.
I put the Pearce pinky extensions on my mags, improved my accuracy with the full grip, and didn't really print any more when concealed.
Not bad guns at all. They, as mentioned, are one of the model designs Taurus got right.
