Frequently bought together:


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.

    Holosun 509T

    Posted by Damien Hall on 20th Feb 2021

    This is a quality product, probably among the current best on the market. The fully enclosed emitter is definitely a feature worth paying for. The optic itself is extremely well built. I recommend this to most people for general use above anything, even above a Trijicon RMR for the average user. It'll serve you well.
