Optic cut Compatibility and further information;
Option 1 – Shield RMS/RMSc/RMSw, Holosun 507K, Sig Romeo Zero – This cut will PRESERVE the factory rear sight channel but you will need suppressor high sights to co-witness with the optic.
All slides MUST be refinished in at least single color cerakote if being machined. The CNC machine will expose raw steel that WILL RUST if not properly coated, below is a photo sourced from the internet showing what a slide that has not been protected with Cerakote will look like, you do not deserve this. That is why we cerakote ALL slides after CNC cutting for optic.
