Why the Holosun HS407C-RD X3 is the Trusted 2 MOA Red Dot for Carry and Duty Use

Precise 2 MOA Red Dot for Fast Acquisition and Accurate Shot Placement
The Holosun HS407C-RD X3 delivers a crisp, clean 2 MOA red dot using a 650nm red Super LED, providing a precise aiming point that is fast to acquire at close range while remaining accurate enough for confident shot placement at extended pistol distances. The single-dot design keeps the sight picture clean and distraction-free for shooters who prioritise simplicity.

Solar Failsafe with Forward-Facing Photodiode for Automatic Brightness
The HS407C-RD X3 features a forward-facing photodiode that automatically adjusts reticle brightness based on the ambient lighting conditions at the target, working in combination with the Solar Failsafe system that provides backup power from the integrated solar panel. This dual-system ensures the red dot remains visible and correctly brightness-matched in rapidly changing light conditions without manual adjustment.

Shake Awake Technology for Instant Readiness
The Holosun HS407C-RD X3 features Shake Awake — a motion-activated illumination system that powers the optic on instantly when movement is detected and powers it down after a period of inactivity, ensuring the dot is always live when you draw without draining the battery during storage.

Up to 100,000 Hours Battery Life with Side-Loading CR1632
The HS407C-RD X3 delivers up to 100,000 hours of battery life from a side-loading CR1632 battery at Setting 6, allowing battery replacement without removing the optic from the slide and preserving zero between changes.

12 Brightness Settings with 4 Night Vision Compatible Modes
The Holosun HS407C-RD X3 features 12 total brightness settings including 4 night vision compatible levels, with memory recall of the last used brightness setting and a lockout mode to prevent accidental brightness adjustments during carry or holstering.

Reinforced 7075-T6 Aluminium Housing with IP67 Waterproofing
The HS407C-RD X3 is machined from reinforced 7075-T6 aluminium with a hard-anodized finish, rated IP67 waterproof and 5000G vibration resistant, built to handle the sustained recoil of daily carry and high-round-count range use without losing zero.

RMR Footprint for Maximum Platform Compatibility
The Holosun HS407C-RD X3 uses the industry-standard RMR footprint, mounting directly to RMR-cut slides and adapter plates across a wide range of carry, duty, and competition pistols. Multi-coated optics deliver a clear, bright sight picture with minimal colour distortion.
