What do you shoot right now in Production? Have you ever shot/ or do you like the 1911 configuration gun? Those are two big questions that you need to answer before you drop the money. If you are not comfortable with or used to shooting a 1911 style pistol, then you may not want to fire off a couple grand for a STI/SV.
If you are, then you can't go wrong with listening to any of the advise already given.
