I got the TP9V2 (DA/SA version) a few weeks ago. 500 rounds and no hangups whatsoever at this point. It is possibly the best pistol deal on the US gun market at the moment. Cerakoted slide, steel sights, two 18 round mecgar mags and a case full of other goodies for the price they are asking is too good to pass up.
The only upgrade I have made to mine at this point was to improve the DA pull slightly and that was a surprisingly easy job. The factory DA and SA were not bad by any means but making it better looked easy (and was easy) so I did it anyway. Didn't have to polish the feed ramp as it was sporting a mirror finish out of the box. Next step: find a good set of night sights for it.
After tweaking the trigger, accuracy was maybe a little easier to squeeze out of it. Pic is after 18 rounds at 10 yards with a fairly quick pace.
