Adapt Your Sig P320 AXG to The Durable Holosun 509T
The C&H Precision Optic Adapter Plate is a premium mounting solution designed to integrate the robust Holosun 509T enclosed red dot sight with the Sig P320 RXAXG platform. 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.
Holosun 509T Compatibility
This adapter plate converts the Sig Romeo 1 Pro footprint on your slide to securely mount the Holosun 509T. It provides a precise, secure fit for one of the most durable and reliable enclosed red dot sights on the market. 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 an Independent Dovetail Rear Sight.
Precision Machined
Machined from steel 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. The SCRS is made for rifles but can be used with this optic plate also for people who want a larger window. However, it doesn’t integrate as well as the 509T and will be much higher on the gun and almost impossible to co-witness with iron sights.
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 509T or SCRS
- Enclosed emitter design to keep out dirt, snow, and other debris
- All models of the 509T and SCRS also have a solar-powered failsafe to ensure you can always use it, even if the battery is dead.
- 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
