I have a CZSPO1 phantom And the trigger pull on it is atrocious Also. I do not shoot it very much, I prefer my smith and Wesson M&P2.0 metal, It has a much better trigger and it feels better in the hand with the grip design. Just saying.
On the side note when I was shooting my beretta 92 I just got 2 coils off of the factory spring, and it cleaned up the DA trigger quite a bit
