After I mounted a Holosun 507C on my G45 and a HE512C-GD on my Galil Ace Pistol, I can’t go back to irons. If I could I would put a red dot on my 357 Windicator. The HE509T is the quintessential step up from an open reflex, I got my BBR 3.10 back f...

Helpful Positive Review Sealed red dot by Killvon, February 13, 2021
I think this is the game changer for RDS on pistols. I have an open emitter that doesn't work when it gets fogged, mud or snow on the emitter. That can't happen to this. I use the circle dot so there is more chance for me to pick up the reticle if I...

Helpful Positive Review Good so far by Cody, November 25, 2021
Out of the box it works great and mounted up great to my gen 5 MOS g19 with a separate mount I bought from c&h precision. It zeroed fine and with only a 100 rounds through it I like it so far. It does have a slight blue tint to it but it doesn’t both...

The HE509T pistol red dot has a tough, lightweight titanium housing with an enclosed design for better protection against the elements than open reflex optics. The multi-coated lenses provide a bright, crisp sight picture in any conditions. Plus, the parallax-free views and unlimited eye relief offer maximum ease and comfort for nearly any shooting activity.image

Featuring Holosun's most popular technology like Shake Awake and Solar Failsafe that conserves power by sensing movement and automatically adjusts reticle brightness to match your lighting conditions. The Holosun Super LED gets up to 50,000 hours of battery life from the included CR1632 battery. The HE509T-RD also features the Multi Reticle System (M.R.S.) that lets you switch between the 2 MOA dot and 32 MOA circle reticle to become just the 2 MOA dot. You can further customize your viewing experience with 12 total brightness settings, including 2 for night vision. Grab this Holosun handgun sight with the included Holosun RMR plate today to improve your target acquisition speed and shot accuracy in close- to mid-range engagements.

Features of Holosun HE509T Reflex Optical Red Dot Sight

  • Up to 50,000 Hours Battery Life (Setting 6)
  • 12 Brightness Setting: 10 DL & 2 NV Compatible
  • Enclosed Design & Titanium Housing
  • Convenient Tray Battery Compartment
  • Parallax-free & Unlimited Eye Relief
  • Shake Awake Technology: Holosun's Shake Awake Technology shuts the LED off during periods of motionlessness. The amount of time it takes for the LED to deactivate (enter Sleep Mode) is user programmable. Shake Awake can also be completely deactivated which keeps the optic powered on for up to 100k hours (certain models).
  • Memory
  • Solar Failsafe: Holosun's Solar Failsafe Technology is an innovative feature pioneered by Holosun in red dot sights. Solar Failsafe allows the red dot sight to remain powered when your battery fails. Holosun optics with Solar Failsafe feature automatic brightness adjustment; when you're under the sun you have a bright reticle, when you move indoors it will automatically dim down to match ambient lighting conditions.
  • Multi Reticle System (M.R.S.): M.R.S. gives the user the flexibility to use their optic as they need it. Units with this feature allow the user to turn on or off certain sections of the reticle giving the ability to have the ideal reticle for the job at hand.
  • Super LED: Holosun Super LEDs provide a versatile range of intensity for the brightest environments down to no-light situations.
  • Multilayer Coatings: Holosun red dot sights and magnifiers are manufactured using optical glass with multilayer coatings applied to facilitate maximum light transmission and wear resistance while reducing glare.
  • Titanium: Holosun's use of Grade 5 Titanium in certain Elite Series red dot sights produces unparalleled strength and durability.
