Holosun 509T X2 Enclosed Pistol Red Dot Sight

The Holosun 509T X2 features a durable titanium housing and a fully enclosed emitter to resist the elements. This rugged pistol red dot includes a Trijicon RMR adapter plate for your favorite optics ready pistols, such as the Glock MOS line. After installing the plate, simply tighten down the 509T’s integrated mount, and your pistol is good to go, with 50,000 hours of battery like Shake Awake, and Solar Failsafe.

The Holosun circle dot reticle also makes getting on target fast and easy. The 32 MOA circle helps you get on target after drawing from your holster, so you can make fast, accurate shots. With the 1 MOA click adjustment, you can effectively zero your pistol precisely for its effective range. Plus, it’s tough enough to perform reliably for thousands of rounds, rated for up to 5000 G’s from recoil.

Note: The RMR adapter plate is not compatible with ZEV or Shadow Systems RMR cut slides.

Red Dot or Green Dot?

Holosun makes this sight with a red emitter, or a slightly more expensive green emitter. As for which one is right for you, it depends. Both models have the same features and incredible battery life, though some shooters prefer the green dot because it catches their eye faster than the red reticle.

One thing to consider is your shooting environment. If you have a lot of green in your background, the red version will provide you with better contrast. In arid environments with reddish soil, the green reticle will stand out more. It depends on your eye and your situation; but in our experience, it’s down to personal preference: you can’t go wrong.
