SCS stands for Solar Charging Sight, and the point of it is simple: no battery to change, ever. The SCS runs on a solar panel feeding a sealed internal rechargeable cell with a 20,000-hour reserve — Holosun states it can operate indefinitely with regular exposure to light. This version mounts directly to the Walther PDP slide cut with no adapter plate and projects a green multi-reticle system. UPC 810047072850.

Three Reticles, One Optic

The Multi-Reticle System lets you cycle between a 2 MOA dot, a 32 MOA circle, and the circle-dot combination. The circle-dot is fastest to find at close range; the bare 2 MOA dot is cleanest for precision. It's a real advantage over single-reticle optics, and it's selectable on demand rather than at purchase.

Green at 540nm

The reticle runs green at 540nm — the wavelength the human eye perceives most brightly, which means a green reticle appears sharper and more vivid than a red one at the same actual output. That is why many shooters find green faster to pick up in daylight.

Automatic Brightness with Manual Override

Brightness is fully automatic — the sight reads ambient light and adjusts. For situations where you want maximum output locked in (bright sun, snow, a white wall), a Brightness Override pins the reticle at setting 9 for 30 minutes before returning to auto. The sight also includes Shake Awake, Lockout Mode to prevent accidental button presses, and a low-battery warning at startup.

Direct Mount, No Plate

The SCS-PDP-GR mounts directly to:

• All Walther PDP Full Size and Compact models with the Walther PDP 2.0 slide cut
• All Walther PDP F-Series pistols

No adapter plate is required, which removes a stack-up of parts and screws and lowers the optic on the slide. It co-witnesses with standard Walther PDP factory iron sights.

Holosun SCS-PDP-GR Specifications

Who This Optic Is For

Walther PDP owners — specifically those with the PDP 2.0 slide cut or an F-Series pistol — who want a duty or carry optic they never have to open. The 5000G shock rating and sealed power system make it a strong choice for a gun that gets carried daily and shot regularly.

Frequently Asked Questions

Is it really battery-free?

Not quite. There is a sealed internal rechargeable cell that the solar panel keeps topped up. You never change it, and it holds a 20,000-hour reserve, but it is not a purely solar optic.

Will it fit my Walther PDP?

Only if your pistol has the PDP 2.0 slide cut (Full Size or Compact) or is an F-Series. Original PDP slide cuts are not listed as compatible — check your slide before ordering.

Can I set the brightness manually?

Not to arbitrary levels. Brightness is automatic; the only manual control is the 30-minute override that locks it at maximum.

Does it co-witness?

Yes, with standard Walther PDP factory iron sights.
