I owned a TSO and shot it for a season. It had a great trigger, I had an oversized safety, thumb rest and Lok palm swell grips. I loved the gun, but fealt it was just a bit small/awkward once I had installed the upgrades. The position of the thumb safety also caused some issues when gripping for me. I would recommend you consider what I will look like after your preferred upgrades. For reference, I wear a Large size glove. I finally gave up and currently have a 2011 Limited being built by Don.
