Holosun HE509T X2 Elite Reflex Sight - 1x Selectable Reticle, Solar/Battery Powered, Titanium Matte Finish

The Holosun HE509T X2 Elite is a reflex sight purpose-built for pistol shooters who want rock-solid performance without the fuss. This enclosed optic pairs Holosun's proven Super LED technology with dual power sources — battery and solar — so you get a sight that runs when you need it, backed by a titanium housing that handles the recoil and wear of serious carry and competition use. Whether you're running it on your duty gun, competition rig, or personal defense pistol, the HE509T X2 Elite delivers the speed and reliability that defensive and sport shooters depend on.

What sets this sight apart is its flexibility. The selectable reticle system gives you a 32 MOA circle with a 2 MOA center dot — pick the reticle that suits your shooting style and distance. The Solar Failsafe means the optic keeps working even if your battery dies, and the Shake Awake feature means the sight only stays active when you're using your gun, stretching battery life to an impressive 50,000 hours. A new Lock Mode lets you disable the buttons with a long press, preventing accidental adjustments in the holster or during a training day. Programming is easier than before, and the improved glass clarity means a cleaner sight picture when it matters.

Installation is straightforward thanks to the included 509T RMR adapter plate, though you'll want to confirm compatibility with your specific slide cut — this plate doesn't work with ZEV or Shadow Systems style interfaces. The CR1632 battery sits in a port that doesn't require removing the optic from your firearm, so battery swaps stay quick and field-friendly.

Frequently Asked Questions

Is the HE509T X2 Elite compatible with my slide cut?

The optic comes with a 509T RMR adapter plate. However, this plate is not compatible with ZEV or Shadow Systems style RMR interfaces. Check your slide manufacturer to confirm compatibility before ordering.

How do I change the battery without taking the sight off my gun?

The CR1632 battery port is designed for field access — you can swap batteries without removing the optic from your firearm, keeping your setup on the gun and zeroed.

What happens if my battery dies?

The Solar Failsafe feature keeps the sight operational even with a dead battery, as long as there's ambient light. This gives you a reliable backup power path for carry and defensive use.

Can I lock the buttons to prevent accidental adjustments?

Yes. Lock Mode disables the buttons with a deliberate long press, preventing unintended brightness or reticle changes when the sight is holstered or in your range bag.
