This service includes modification of the Sig factory Romeo 1 cutout and re-drill/tap of new mounting holes to accept the Trijicon RMR or Holosun 507c. You will still be able to use the factory cover plate unless specified otherwise. You will still be able to mount the Romeo 1 optic.
Appropriate mounting screws will be included for the optic selected.
Slide refinish may not be needed in all instances, but the hole modification process may damage the existing finish within the cutout area as shown in the pics.
You may see all available Cerakote H-Series colors by clicking HERE.
This service is currently only listed for Trijicon RMR/Holosun 507c conversion. Other optics may be used, just contact me first since the modifications will result in a larger cutout and although it will still mount, the factory cover plate may have a larger gap due to the larger cutout.
