For the P-01/SP-01, the front edge will be cut to a depth of 0.170". It must come with a sealing plate. This is because the sealing plate will now be integral to the safety plunger working correctly. The rear iron must also be removed due to the length of the RMRcc footprint.
Sometimes iron's can be damaged during removal and installation (rarely with CZ's, but it can still happen). Any service requiring finishing will need to have them removed. We will not be held liable for any damaged iron sights if they need to be removed in order to service your slide.
