Specifically designed for pistols, the HE509T features an enclosed design that protects the emitter within sealed tubes, so it can't be obscured by water, mud, and dust. The body is made from Holosun®'s Grade 5 titanium body, which provides more than double the tensile strength and as high as 5X the fatigue strength of aluminum.

It's an ultra-tough Red Dot Sight, but it's what's inside that counts. And inside the HE509T is a handful of Holosun's premier technologies. First and foremost is Solar Failsafe, which uses ambient light to power the Sight in the event of a battery outage. Next up is Shake Awake technology, which "wakes" the Sight at the slightest movement and shuts it down during periods of inactivity. Once "awake," the 590T provides your choice of 2 MOA Red Dot, 32 MOA Circle Dot. It all adds up to one of the finest dedicated pistol micro Reflex Sights we offer.
