This year at SHOT Show 2020 Holosun unveiled its newest red dot optic, the 509T. It is a pistol optic (that can also be used on carbines) that features an enclosed emitter. While for some an enclosed emitter may not seem like a big deal, you might want to get out more…

The Holosun 509T has a smaller footprint than other enclosed pistol mounted optics.

The 509T’s new enclosed emitter really begins to shine when you take it outside. Shooting at indoor ranges is often fun and largely convenient, but when you step outdoors you meet the reality of the elements. If you have ever had a reflex sight become unusable due to water, snow, mud or other debris obstructing the emitter, you know what I mean. It is the Achilles’ Heel of reflex sights. The new Holosun 509T alleviates this problem.

The buttons on the 509T are larger than previous Holosun models, making it easier for users to adjust the brightness, even when wearing gloves.

The 509T can be used in either auto mode, switching between 2 brightness settings and largely relying on the solar cell across the top, or in a manual mode. In manual mode, the optic can be adjusted between 12 brightness settings, the lowest 2 being compatible with night vision.

The reticle features a 32MOA circle and/or 2MOA center dot, available in both red and green, with a battery boasting a 50k hour life. The 509T uses a cross-bolt to attach and will ship with a Glock MOS Mounting Plate.

Users can select between a 32MOA circle, 2MOA dot or both. Above is the 32MOA circle by itself.

The Holosun 509T will be available Q2 with MSRP of $509 and a street price of $430. Check back later, for when we bring you a full review.

    I have a HOLOSUN 509T and really like all the features, and that all these features are truly very useful. I almost feel sorry for AIMPOINT ACRO owners.
    My 509T is my my RuGER 57 pistol.

    The data sheet in the article says “65 MOA Circle” but “32 MOA circle” is mentioned in the article.
