Px4's are good to go IMO
...
For the very most part yes..
My original Px4 40, bought NIB Jan 07, (and most T/S cases, 98%, were in the 40cal models of DA/SA)
In just over 1 year, after 2000 rounds it began to sting, namely during colder temps but come summer, my gun now had nearly 4000 rounds and it became 2 cold mags worth (20) shots or a tad more to finally warm up the gun enough for whatever it was that was causing the trigger sting to go away.. My bet is "flex" finally kicked in, via heat, and the T/S stopped. But cold and rigid guns, back then, were not possible to continue firing past 20 rounds unless gloves were worn.
After 4000 rounds thru 6450 flawless rounds, it was full time, any time, all the time and I, finally, sent it back, went thru a 6 month, 3 week, pure headache, to finally demand send back my original gun or send me a NIB replacement.. "Small claims court" will be next
They did finally did. And I did notice some changes, one that could be seen, the other that could be felt (trigger SA engagement)
First gun was a PY 125** and the NIB replacement was PY383** and now, with over 3000 flawless rounds over 3yrs and thru cold temps, hot temps, any temp/weather, it has not shown any trigger sting..
So, I think it is fairly safe to say, you will not have any problems regarding trigger sting but I must mention that the triggers very thin and sharp end/s can, if one over-places one's trigger finger, too much, one can get a felt pinch, which can be easily corrected by not putting in quite so much trigger finger/application/pull..
Great guns, soft shooters, balanced, with the rotating barrel effect..
Accuracy is spot on with them.. with or without laser
OMMV
