I recently purchased (used) a TSO in .40. Love the handling characteristics, but have yet to shoot it to its potential. However, immediately I was having trigger reset issues, i.e., not letting the trigger reset between fast pairs and getting the "freeze". As far as I can tell, no one makes an extra power trs for the TS or TSO. I think we need this. I know another owner of a TSO experiencing the same issue.
I did a temp fix by bending the leg of the spring that attaches to the trigger bar 45 degrees. It helped, but I'm sure it will relax after awhile.
