Sig P365 RMR & Holosun 507c Optic Mount | EGW Guns


Unlock the true potential of your standard Sig P365 by mounting a larger, duty-grade red dot sight. This EGW optic mounting plate is the most rugged and reliable solution for installing a Trijicon RMR, Holosun 507c, or any RMR-footprint optic onto your P365 slide. Precision-machined in the USA, our dovetail mount provides a rock-solid foundation for the ultimate concealed carry setup, without the need for expensive and permanent slide milling.

Firearm and Optic Compatibility

  • Sig Sauer P365 (Standard Model) non optics ready

This Mount is Compatible With The Following Red Dots:

  • Holosun 407c / 507c / 508t
  • And any other optic that uses the Trijicon RMR footprint.

The EGW Solution for the Sig P365

The secret to a reliable red dot setup is a mounting plate that won't shift or fail. Here’s why our P365 plate is the superior choice:

  • Dovetail Mounting System: Our plate replaces your factory rear sight, using the empty dovetail cut to create an incredibly strong and stable platform without the need for permanent slide modification.
  • Machined from 7075 T6 Aluminum: We CNC-machine each mount from a solid block of American-sourced, aerospace-grade 7075 T6 aluminum. This provides the strength of steel at a fraction of the weight, which is critical for a lightweight carry pistol like the P365.
  • Includes All Necessary Hardware: The plate comes with all necessary screws and hardware for a secure installation.
  • Proudly Made in the USA: Every component is manufactured in our Pennsylvania facility and is backed by a lifetime of service.

Sig P365 RMR Mount FAQ

Will this fit my Sig P365X or P365XL?

No. This plate is specifically for the standard Sig P365 that has a rear sight dovetail. The P365X and P365XL models are already cut for a micro-optic (like the Holosun 507k) and do not have a rear sight dovetail, so this plate is not compatible.

Why mount a larger optic like an RMR on a P365?

While micro-optics like the 507k are popular, many experienced shooters prefer the larger window and proven durability of full-size red dots like the Trijicon RMR and Holosun 507c. A larger window can make it faster to find the dot under pressure. Our plate makes it possible to get big optic performance on a small, concealable pistol.

Is gunsmith installation required?

We always recommend professional installation by a qualified gunsmith. A gunsmith has the proper tools (like a sight pusher) to remove the factory rear sight without damaging the slide's finish and can ensure the EGW plate is fitted perfectly and securely for a reliable, return-to-zero hold.

Important Fitment Information

This mounting plate is designed to replace the factory rear sight on a standard Sig Sauer P365 slide. It will NOT fit P365 models that are already cut for an optic (P365X, P365XL, etc.).
