Holosun HS407C-X3-RD is a compact open reflex red dot designed for pistol platforms using the RMR footprint. It delivers a clean 2 MOA dot, strong aluminum construction, and smart power management features that make it reliable for everyday carry, duty use, and range shooting.

Clear aiming, faster shooting

The precise 2 MOA gold dot allows for quick target acquisition without covering too much of the target. Combined with a clear, multi-coated lens, it gives you a sharp sight picture in both bright daylight and low-light conditions.

Always ready when you need it

With Shake Awake technology, the optic automatically turns on when you move your firearm and powers down when idle, saving battery life. Brightness settings are remembered, so it’s always ready in your preferred configuration.

Smart brightness & solar backup

Automatic brightness adjustment adapts the dot intensity to ambient light conditions. Solar Failsafe ensures the reticle remains visible even in changing light, adding an extra layer of reliability when it matters most.

Battery without removing the optic

The side-loading CR1632 battery tray allows quick replacement without removing the sight from your slide, so you keep your zero and avoid unnecessary reinstallation.

Built for real-world use

The 7075-T6 aluminum housing provides excellent durability while keeping weight low. With IP67 water resistance and high shock resistance, this optic is built to handle demanding conditions without compromise.
