Fitment

What red dot fits a Ruger RXM Optic Ready?

The Ruger RXM Optic Ready ships with one slide cut that takes RMR, DeltaPointPro and RMSc pattern optics. Optics mount directly on the native cut only.

Verify before buying. Fitment data is sourced and last-verified per row, but slide cuts and plate compatibility change across model years and runs. Always confirm the exact cut and plate against the manufacturer before you purchase.

Good to know

Ruger lists 27 RXM models. The 21 this page covers, including model 19400, carry Ruger's optic pattern "RMR, DPP, RMSc". Ruger's own abbreviation is "DPP" and it does not expand it; we read it as the Leupold DeltaPoint Pro pattern. Six Lipsey's Distributor Exclusive models, 19461 through 19466, instead carry the optic pattern "Aimpoint A-CUT", a slide-integrated interface that Aimpoint says requires no screws inside the optic housing and that its COA sight mounts through exclusively. The optics named here do not apply to those six models, and neither maker publishes what else an A-CUT slide accepts, so check the model number on your own pistol before you buy. Ruger publishes no screw thread or screw length for the RMR, DPP and RMSc cut, and lists nothing in the box but two magazines and a carry case, so no adapter plate is involved.

Direct fit (native slide cut)

These optics drop straight onto the factory cut. There is nothing extra to buy; where an optic ships its own plate in the box, the row says so.

Fits with an adapter plate

No adapter-plate paths tracked for this gun.

Fits with a footprint adapter

These optics mount once you add a footprint adapter: a plate that bolts into this gun's own optic cut and presents a different footprint on top. It is a separate part from a different maker, so check the maker's own fit notes against your slide before buying.

No known adapter

We have not found a real adapter that mounts these optics on this gun. We list them honestly rather than guess. If a plate exists, send us the source and we'll add it.
