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.

Check a specific pairing

The interactive fit checker opens with this pistol already selected and gives you a single verdict for any optic, plus a build sheet with the plate SKU, screw threads, torque figures and install order. Every "how it mounts" cell above opens that pairing's verdict — the most asked-about ones on a page of their own, the rest in the fit checker — at an address you can send to someone.

Deciding between a few? Compare 3 of the most-asked-about optics on this slide side by side — window, weight, emitter, cost to mount and sight co-witness.

Something on this page wrong? Say what it should be. Corrections from someone who owns the pistol are why this is worth more than a spec sheet — and nothing here changes without a source, so bring one.
