Holosun SCS-320-GR Red Dot: Solar Powered, Endless Battery

Red dot sights have transformed how shooters engage targets: faster sight acquisition, intuitive aiming, and adaptability across applications from competitive matches to defensive carry. For modern striker-fired pistols and optics-ready slides, choosing an optic that minimizes maintenance while maximizing uptime is critical — especially when reliability matters most.

HOLOSUN 2 MOA Green Dot/32 MOA Circle Multi Reticle

The HOLOSUN 2 MOA Green Dot/32 MOA Circle Multi Reticle is the SCS-320-GR Solar Charging Sight designed specifically for P320 optics-ready handguns and other DPP footprint applications. Priced at $399.99, this optic brings Holosun’s multi-reticle concept together with an innovative power system that reduces downtime and increases readiness for everyday carry and duty use.

Why the SCS-320-GR stands out in Red Dot Scopes

Holosun built the SCS-320-GR around two priorities: seamless integration and near-permanent power. The sight attaches directly to slides with a DPP (P320) footprint — no adapter plates required — making it an excellent drop-in solution for SIG P320 owners and compatible slides. The combination of a precise 2 MOA dot with a 32 MOA circle gives shooters a fast, versatile aiming point suitable for close-quarters work and controlled precision at moderate distances.

Key features and how they matter

Solar charging system with multi-directional sensors

What separates this model from many battery-first optics is the innovative solar charging system. Multi-directional light sensors automatically adjust brightness in dynamic lighting, maintaining reticle clarity indoors and outdoors while conserving internal charge. This feature is ideal for users who train in variable light or transition frequently between environments.

20,000-hour internal rechargeable battery

The SCS can potentially operate indefinitely under reasonable exposure to bright light thanks to its internal rechargeable 20,000-hour battery. For most users, regular daylight exposure will keep the optic charged without ever needing a battery swap. If you need a temporary power spike, the intensity override function locks the optic into a high brightness mode for 30 minutes — useful for bright daylight or when wearing eye protection that reduces contrast.

Low power warning and waterproofing

A low power indicator warns you days before charging is required, providing predictable maintenance windows rather than surprise failures. The SCS-320-GR is rated IPX8 waterproof, so it can take exposure to wet conditions and remain functional — a must-have for field use and adverse weather scenarios.

Compatibility, mounting, and installation

The sight is explicitly designed for P320 optics-ready slides and DPP footprint plates, eliminating the need for adapter plates in most installations. Mounting is a straightforward process for anyone familiar with slide optics: remove the plate or cover, fit the sight to the DPP footprint, torque the screws to spec, and verify zero. Because the optic attaches directly to the slide, attention to slide-to-sight interface and screw torque will ensure lasting zero retention during use.

Practical setup tips

When installing on a P320 or compatible slide, use the correct threadlocker if recommended by the slide or gunsmith, confirm slide-to-sight flatness, and perform a live-fire verification at multiple distances. For guns used in duty or carry roles, a daily carry check should include a quick brightness verification and visual inspection of the optic base.

Field performance and real-world applications

The HOLOSUN 2 MOA Green Dot/32 MOA Circle Multi Reticle is tailored for defensive carry, close-quarters training, and range work where fast target acquisition is critical. The 2 MOA dot enables precise shot placement while the 32 MOA circle offers quick, instinctive aiming points at close distances — a combination appreciated by competitive shooters and operators alike.

Because the optic uses solar charge and includes an intensity override, operators who spend extended periods outdoors will see very low maintenance and reliable reticle brightness. The IPX8 rating means routine exposure to rain or sweat won’t sideline the sight.

Maintenance and longevity

Maintenance is largely preventative: keep the lens clean, periodically verify brightness settings and low power indicator, and ensure the optic’s mounting screws remain torqued to specification. The 20,000-hour rechargeable battery reduces lifecycle costs and the need to carry spare batteries, making long-term ownership economical.

Who should consider this optic?

If you own a P320 or another DPP-compatible slide and want a low-maintenance, high-performance optic, the SCS-320-GR is an excellent option. It’s equally at home on a daily carry setup or as part of a training rig. Holosun’s reputation for rugged optics and the SCS’s solar charging and IPX8 rating make it a practical choice for users who prioritize uptime and durability.
