Ruger RXM Optics: Everything You Need to Know

The Ruger RXM is one of the most versatile optics-ready pistols available today. Its standout feature is a "modular pin" mounting system (similar to the Springfield Echelon) that eliminates the need for bulky adapter plates for most standard footprints.

Understanding the Ruger RXM Multi-Footprint System

Unlike most pistols that use a single fixed cut, the Ruger RXM footprint is designed to adapt to you. The slide features several screw holes and utilizes sets of removable pins that act as recoil bosses:

• RMR Pin Set : Use this for larger optics like the Holosun 407C, 507C, or Trijicon RMR. Note that these optics will have a slight overhang on the sides of the slide.
• DPP Pin Set : Designed for the DeltaPoint Pro footprint. This is the pin set to use for the Holosun SCS 320, or Vortex ST/XL series.
• RMSc Pin Set : Use this for smaller CCW red dots with a true RMSc footprint, like the Osight SE. These sit flush with the 1" slide for a much sleeker profile. Important Note on Holosun K-Series/EPS : While these use a modified RMSc footprint, the Ruger factory pins are too tall for the optic to sit flush. You’ll need to use our RXM-to-K adapter plate to avoid having to file down your factory pins.

Top Rated Ruger RXM Red Dots by Use Case

• Duty & Reliability : The Trijicon RMR and Holosun 509T are perfect for ruggedness.
• Competition : For a massive field of view, the Holosun 507 Comp or Trijicon SRO are top picks.
• Best Enclosed Carry Optic : The Holosun EPS (Full Size or Carry). Enclosed emitters are the gold standard for everyday carry reliability.
• Best Flush-Fit Option : The Holosun 407K or 507K . These match the RXM's slide’s width perfectly, preventing snagging on clothing or holsters.

Frequently Asked Questions (FAQ)

Does the Ruger RXM come with optic mounting pins? Yes, Ruger includes several sets of pins in the box. You must consult your manual to ensure you are using the correct pin set (RMR, DPP, or RMSc) for your specific optic to prevent the screws from shearing under recoil. If you are installing a Holosun K-Series or EPS optic, you will need this RXM-to-K Series Adapter Plate to ensure a secure fit.

What is the footprint of the Ruger RXM? The RXM has a multi-pattern cut. It natively supports the Trijicon RMR, Leupold DeltaPoint Pro, and Shield RMSc footprints by swapping the internal pins.

Can I co-witness with the factory sights? Yes! The Ruger RXM comes with co-witness height sights. Most Ruger RXM red dots mounted directly to the slide (especially RMSc and DPP footprints) will allow for a functional co-witness. You can see the RMR and DPP cowitness here, and the Holosun K/EPS cowitness here.
