Looks like I'll be getting the entire slide painted with Cerakote on Monday. I've read a lot of good reviews on Cerakote and I'm hoping that the finish will withstand the hammer strikes on the back better than the CZ factory coating. I'll keep people posted on this thread as I go in the next days, months, etc.
I actually called the company and asked them about whether Cerakote will withstand hammer strikes on the back, and they said yes. We'll see how this holds up.
