Description
The Holosun SCS-320-GR is a dot sight designed as a direct fit for Sig Sauer Optics-Ready P320 pistols. It is compatible with platforms featuring a DPP-standard footprint mount. By mounting directly onto the pistol’s slide, the sight maintains a low profile, eliminating the need for adapter plates and ensuring maximum stability of the optic on the firearm.

Distortion-free image through an aspheric lens
The optical system features an aspheric lens that provides a clear, distortion-free image across the entire reticle window. This enables more intuitive binocular aiming. Multi-layer optical coatings ensure optimal light transmission, and minimized parallax ensures that the selected reticle remains on the target regardless of the viewing angle.
Solar Power for Maximum Lifespan
The SCS-320-GR model uses a solar panel to charge its built-in rechargeable battery. This small energy storage feature ensures that sunlight levels do not affect the collimator’s operation. The device automatically recharges from light sources, providing an operational reserve of up to 20,000 hours.

MRS System and Intelligent Backlight Control
The MRS system allows the user to select one of three available reticles: a 2 MOA dot, a 32 MOA circle, or a combination of a dot and a circle, all generated by a green LED with a wavelength of 540 nm. The reticle position can be adjusted within a range of +/- 30 MOA vertically and horizontally, with a click value of 1.5 MOA.
The Multi-Sensor Auto Brightness system automatically controls the reticle illumination intensity by continuously analyzing lighting conditions and adjusting the reticle’s brightness to match the surroundings. In situations requiring maximum contrast, the shooter can use the Brightness Intensity Override feature, which allows manual activation of full reticle brightness. This enables immediate adaptation of the sight to rapidly changing conditions.

Durable Housing and Direct Fit
The red dot sight’s body is made of durable 7075 T6 aluminum with a durable, black anodized finish. The design features high resistance to shocks and vibrations caused by strong weapon recoil of up to 5,000G. The device meets the IPX8 waterproof rating, ensuring high protection against dust and resistance to submersion in water, enabling reliable operation in temperatures ranging from -30°C to 60°C.
Thanks to its dedicated Direct Fit design, the red dot sight mounts directly onto the slide of Sig Sauer Optics-Ready P320 pistols and platforms with a DPP footprint rail without the need for mounting plates. The low-profile optical axis allows for use with factory-installed mechanical sights in a co-witness configuration.
