I keel going back and forth on this.
My Kahr has a great DAO trigger.
My CZ has a nice DA/SA pull, and with it's lightened hammer spring my first shot really isn't thrown off all that much. Pull the gun, shoot.
My other CZ is being converted to SAO. It'll take some getting used to but having a constant trigger pull from the start is nice. I just have to gain muscle memory to swipe off that safety first.
