Adapt Your Sig P320 to The EPS and EPS Carry
The C&H Precision Optic Adapter Plate is a premium mounting solution designed to integrate the robust EPS enclosed red dot sight with the Sig P320 X5 and M17/18 platforms. Engineered for durability and precision, this adapter plate ensures a rock-solid fit, enabling you to enhance your firearm’s accuracy and speed in any shooting scenario.
Designed for Holosun EPS Footprint
This adapter plate converts the Sig Romeo 1 Pro footprint on your slide to securely mount the Holosun EPS, EPS Carry, or SCS Carry. Please check if your P320 has the Romeo 1 PRO footprint as opposed to the older Romeo 1 footprint. Additionally, make sure your P320 has a Plate Intergrated Rear Sight. This plate comes with an integrated rear sight since users with these pistols would normally lose their rear sight when installing an optic.
Precision Machined
Machined from 6061 aluminum for long-lasting durability, ensuring a solid and stable fit for your optic under heavy recoil and rigorous use. Every C&H Optic Plate is designed, manufactured, and machined in the United States at a small family owned business. Each plate is precision machined to the tightest tolerances on HAAS CNC machines and each plate goes through multiple quality checks before shipping to customers.
Low-Profile Design
Maintaining a thin and unobtrusive profile keeps your firearm looking good and doesn’t raise your optic absurdly high.
Easy Installation
Includes all necessary hardware for a quick, hassle-free setup, allowing you to install the adapter and confidently mount your optic.
Benefits of Switching to the Holosun EPS or SCS
- Enclosed emitter design to keep out dirt, snow, and other debris
- Low enough design to work with most factory handgun iron sights
- Most models of the EPS also have a solar-powered failsafe to ensure you can always use it, even if the battery is dead. The SCS however does not have a removable battery and is only solar-powered.
- The EPS Carry and SCS Carry have a rear sight channel cut into the optic
- The ability to change batteries without removing the optic means you don’t have to re-zero every time the battery is changed, unlike the Trijicon RMR
