Trijicon RMRcc Footprint – What You Need to Know

If you’re running a concealed carry setup and considering a micro red dot, understanding the Trijicon RMRcc footprint is critical. Unlike the original RMR, the RMRcc was designed specifically for slim-profile pistols, offering a compact reflex sight that’s tailored to the needs of today’s carry-focused shooters.

Mounting optics can get confusing — this guide clears it up so you know exactly what to expect when it comes to fitting, compatibility, and performance.

🔍 What Is the RMRcc Footprint?

The RMRcc uses a proprietary two-screw mounting system that differs from the standard Trijicon RMR. This footprint:

• Uses two horizontally spaced screw holes
• Does not include recoil lugs
• Requires a dedicated mount or adapter plate
• Was purpose-built for slim carry pistols like the Glock 43X MOS, Springfield Hellcat, and Sig P365 XL (with appropriate adapter)

Because it’s not cross-compatible with RMR or RMSc footprints, the RMRcc requires proper slide milling or an adapter specific to its unique design.

❓ FAQ

Q: Will the RMRcc fit an RMR cut slide?
A: No. The RMRcc footprint is narrower and uses different screw spacing. You’ll need a specific adapter plate or custom milling.

Q: Is the RMRcc compatible with Shield RMSc or Holosun 507K footprints?
A: No. The RMRcc footprint is unique and not interchangeable with RMSc, Holosun, or Docter footprints.

Q: What tools do I need to mount an RMRcc?
A: A T10 Torx driver, thread locker (like Loctite), and your manufacturer’s recommended torque specs.

Q: Can I mount the RMRcc on a Glock 43X MOS slide without an adapter?
A: Yes — if your slide was cut specifically for the RMRcc. Otherwise, you'll need an RMRcc to Glock MOS adapter plate.

Q: Does Mounts Plus sell the adapter plates?
A: Yes. We carry adapter plates for Glock MOS, Sig P365 XL, Springfield Hellcat, and more.
