Those who have experienced a 9mm 1911 will be likely to be big fans on range days when the extra rounds and reduced recoil allow for more time making holes downrange, and exhibiting a big grin. STI's original single-stack 5.0 Tactical is a hoot, IMO.
^ + 1 for what Old Bill said. Live with it a while before you have a smith muck with it. You might be surprised and be happy with it. Stranger things have happened. Do what makes You happy.
