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, the factory rear sight will be machined with the optic cut to allow for the optic and a Dawson Precision .265 front sight is available to give a lower 1/4 co-witness.
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.
