Hey 2 J's....I would not say so much the trigger is better just a little different. I think it is the trigger designed initially for the P-07 polymer CZ and allows a decocker to be added instead of a saftey. There are some other subtle differences too. i have been told the newly engineered Omega trigger mechanism improves trigger travel uses fewer parts so to enhance the service live of the weapon. However, the main advantage, like I said, is really easy interchange of decocking lever or manual safety.
I hope this helps. have a great week end bud. i will be going ice fishing.
