Does the Vortex Defender-CCW fit the GLOCK 17 / 19 / 45 Gen6 (ORS)?

No: the slide is not cut for the Shield RMSc footprint, and no plate listed here bridges it.

No known fit

Nothing in this database bridges the GLOCK Gen6 ORS interface to the Shield RMSc pattern. The most widely milled cut on carry-size pistols. Accepts Holosun K optics, which simply leave the rear lugs unused. A custom plate or a re-mill would be the only route — check with a plate maker before assuming it can't be done.

How this slide mounts an opticReplaces MOS on Gen6. Polymer spacer plates screw the optic directly into the slide, so the optic sits lower and there is no metal plate to work loose. Early field reports include optics rotating on the polymer without visible witness-mark movement — check zero often and re-torque on a schedule.
