Taurus PT-99 not resetting in SA

[jetinteriorguy]

I just recently purchased a Taurus PT-99 used and am having trouble with it resetting into SA. Usually about 30% of the time it doesn’t reset and I just wind up shooting it DA instead. Whenever I manually cycle it, it resets every single time. I’ve recently installed an MCARBO spring kit and double checked everything and it’s all in correctly and seemingly functioning properly.

 

[10-96]

On the right side of the frame, beneath the grip panel, is there a trigger bar spring spring pushing upwards on the trigger bar like the Berettas? It sounds like something is not allowing the trigger bar to go upwards enough during the cycle.

I checked that and it’s installed correctly. So I got to thinking and figured it had to be something with the sear spring, I pulled off the grips and reviewed the installation video and discovered I had installed the spring upside down. I’ll head to the range tomorrow for some testing, but I’m pretty confident this was the problem.
