The Holosun SCS 320 green solar charging sight is an enclosed-emitter pistol optic that mounts straight to SIG Sauer P320 slides (Holosun part no. SCS-320-GR). Holosun designed it to fit P320 optics-ready slides and other DPP-footprint platforms without an adapter plate. It runs on an internal rechargeable power system fed by a solar panel, so there is no battery to replace. The reticle is a green 2 MOA dot with a 32 MOA circle, and brightness adjusts automatically from multi-directional light sensors. It is a good match for a carry or duty P320 that needs a self-powered dot.
