The trigger pull is a combination of the parts used and the care taken in cleaning up/polishing the contacting surfaces.
I know I don't go nearly as far/hard into things as some of the folks here do. I have no issues stoning polishing the flat surfaces. Some of the guys here polish the trigger/hammer pins, the insides of the hammer pin hole in the hammer and other places I let the lube take care of for me.
Probably why my best triggers are a crisp 3 lbs. on a couple B models while my Tactical Sport is 1.7 lbs. (the old TS pistols were also safety models but SAO).
I really don't notice the carry weight of a P01 Omega vs. a CZ75 Compact. Whatever is on the hip/in the holster is forgotten/not noticed after a few days of carrying it (not true for a pistol with an awkward carry, like a P09 or something with a full sized barrel/frame that sticks out/jams up when sitting in the car/truck but that's still not weight, it's awkwardness).
The two worst (rough, draggy, notchy, high trigger pull weight) pistols I ever bought were those two CZ75 Compacts (steel frame with the P01 style rails and ambidextrous safeties) I bought several years ago. Never fired one of them and converted the other to SAO. Not sure why both of those had ugly triggers.
Don't let the internet tell you what is bad about CZ pistols. Get one and try it out yourself. I own several brands of pistols but I carry the CZs and spend too much time/money on those other ones trying to get them to shoot like the CZ's I carry all the time.
