put a few hundred rounds through my new TP9SA already, trigger pull was pretty good, but I thought maybe I could make it just a touch better.  so having no videos out there I just kinda winged it based on my past experience with other handguns... please don't just start taking your pistol apart if you don't know what your doing...
I removed the trigger pin and the rear pin, I then drove out the lower small pin in the trigger itself (this one holds the trigger bar).  I removed the front of the trigger return spring using small needle nose pliers... then I removed the trigger bar.
I took great care in seeing how things went together and exactly where the trigger bar comes into contact with other parts. I polished both sides of the trigger bar where it sits inside the trigger, first with 1000 grit sand cloth then with polishing compound and Q-tips... then I did the same on the side that rides against the inside framewall.  the rear of the Bar had  some wear on one side so I polished that also... then I lightly polished the top of both humps where I saw some wear.
it dramatically smoothed out my trigger pull, don't know if it reduced it any....it was light enough to start. can't wait to shoot it again, just thought I would share.  sorry I have no way to make a video of what I did...it's hard enough just posting a few pics.

How did it shoot?  Any other update?
