Plate to slideper optic manual

How this slide mounts an opticInstead of plates, three sets of self-locking pins drop into the slide to recreate a footprint's lug pattern. Pin set 1 (fitted from the factory) gives RMR, set 2 gives DeltaPoint Pro, set 3 gives Shield. The optic then bolts straight to the slide, so nothing stacks. ACRO and Docter optics still need an adapter.

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.
