Special Features
- The internal solar-rechargeable battery eliminates replaceable cells entirely, charging faster than it drains under even modest indoor lighting and removing battery management from your carry routine permanently.
- Multi-directional light sensors continuously adjust reticle brightness to match ambient conditions automatically, so the dot stays visible in direct sun and never blinds you indoors without any manual cycling.
- The 30-minute manual override locks the optic to maximum brightness on demand, giving you a high-visibility aiming point in direct sunlight or challenging backlit conditions with a single button press.
- The fully enclosed emitter design seals the LED and optics inside the aluminum housing, blocking dust, moisture, and debris from reaching the emitter regardless of conditions.
Practical Benefits
- The DPP footprint mounts directly to Sig P320, M17, M18, P226, and P229 optics-ready slides with no adapter plate, no filler plate, and no gunsmithing, making installation a straightforward drop-in process.
- The 1.35 oz weight adds virtually nothing to a full-size or compact Sig slide, keeping your draw weight, balance, and holster fit consistent with the optic installed.
- Your SCS-320GR gives you a solar-recharged, always-on enclosed green dot that stays powered, stays protected, and never asks you to manage a battery on your most-used carry pistol.
The Holosun SCS 320 Solar Charging Sight (SCS-320GR) with its 32 MOA ring and 2 MOA green dot is a smart addition for Sig P320 and DPP-footprint pistol owners who want a fully enclosed, solar-powered optic that mounts direct to the slide and operates indefinitely without battery changes.
