Just so everyone is on the same page, I scanned in the Exploded View / parts-list I got with my PT140 Pro, are you talking about the "trigger bar"
I know some parts are slightly different, as I have 2 - PT140Pro's (a Gen2 -&- a Gen3) & the Captive Recoil Spring in the Gen3 is Quite a but Larger than the one in the Gen2, but no "note" is made of it in the Parts/List ?? So ?? I hope this helps Someone who knows a Bit more than I do...
Below: is the Entire Page scanned from the "Booklet" (click to enlarge) Just in Case I identified the wrong item....
I hope this Helps someone Answer your Question More accurately than I am able to do at this point in my "Taurus Knowledge Base".....
