Extra power trigger return spring for TSO?

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.

No need. I have 20k rounds through both a TS & TSO and the only reset issues I?ve ever had were because of the trigger pre-travel screw backing out. Loktite that in the position you want and you?ll be fine.

Both the pre and post travel screws must be backed out by at least 1/4 turn, and perhaps even half a turn for safety, from their exact let-off points.
The pre-travel screw messes with trigger reset, and post travel screw blocks the hammer from being released. You could be facing one or both of the issues. Since the TS trigger is plastic, I am not sure how effective loctite would be.

I have the metal flat faced trigger installed and have adjusted both pre and over screws. The small amount of reset is still weak for me. I realize this is as much about shooting technique as anything. I know shooters who are trigger "slappers" and never have issues when shooting at speed. I'm not one of those guys........I spent much time on DA revolvers in my formative years.

I still think a stronger trs would be a nice option.

The need for a stronger reset spring, and the issues of trigger freeze could be considered different matters. While a stronger reset spring would help, the trigger as it is would always reset if the pre and post travel screw adjustments are made correct, and of course there is no other mechanical fault in the weapon.

I wanted to increase trigger weight in my TS (by about 1 lb), and the only solution was with the extra power sear spring (from Tanfoglio) or double sear spring mod. I could not find a heavier trigger return spring (which too would have added a few ounces).
Unfortunately (in your case), the TS is designed to have a very light trigger. The trigger bar is also different, and I recall reading somewhere that it was designed for light weight triggers. You might be better off getting a standard CZ 75 framed pistol, for which there exist some stronger trigger reset springs. You might do better if you contact CZ custom (or CGW) directly on phone or email and discuss with them if they could come up with some solution for the TS.
