Duration:   1  mins

Let’s take a look at the new Holosun HE509T, a rugged titanium-housed closed-reticle red-dot sight designed for competition and defensive pistols.


The Holosun HE509T has a proprietary mount and a side-access battery tray, which means you don’t have to take the unit out of the mount to change the battery. The battery life is up to 50,000 hours at setting 6. It takes a CR1632 battery, which comes with the unit.

It also has Holosun’s trademark, a solar-capable powering system, and Holosun’s Shake Awake function.

The HE509T is adjustable for a reticle that is a dot or a circle dot, which is something a lot of people are looking for, especially people who are new to red-dot sights. They are considering whether they want an open or a closed design in a red-dot sight and also what kind of reticle they want to use. With this optic, you have a choice.

The HE509T has ten daylight and two night-vision brightness settings — compare that to other models from different manufacturers and consider the value and the quality you’ll get from Holosun.

Dimensions in inches are 1.6×1.16×1.13, and the weight of the unit is 1.72 ounces.


As well as a candidate for a competition pistol, this sight may be a great choice for your defensive gear, mounted on a carry gun or a staged home-defense pistol.

      Hello Terry,

      No, the Holosun HE509T isn’t a direct fit for the Hellcat. The Holosun models 407K & 507K are a direct fit for that gun.

      Thank you,
