If II really don't think cops like them per se. In the 80's lawyers went to them as a safety feature and it took off. If you do a thumb high hold on a cz with right thumb resting on the safety, you instantly verify the safety is off before firing.
A da/sa sounds nice but is hard to train for trigger control. Especially if you are not shooting hundreds of rounds per week.
If you think a decocker on a cz is better you are just deceiving yourself ! :
