Different guns.
My P07 had the best out of the box trigger of any new CZ I've bought. 3&1/4 (or was it 3&1/2???) lbs. DA and another 5 lbs. added to that for the DA trigger pull.
The worst out of the box CZ triggers I've gotten were the two steel framed P01 looking CZ75 Compacts. Those, compared to my P07, P09, the Omega P01 and the other CZ75 Compacts were just terrible. I left one alone (never shot it) in the box and converted the other one to SAO.
After all the striker fired guns that preceded my P07 I haven't seen a need to mess with the Omega pistols. Better out of the box than the three brands of striker fired guns and a couple of the hammer fired guns.
I can certainly understand the desire to upgrade a bad trigger. A nice trigger is....nice.
