Features

  • RED DOT REFLEX SIGHT - The HE509T-RD X2 is a hard-use, nitrogen-purged enclosed LED sight designed for handgun applications; It features a grade 5 titanium housing, Super LED with up to 50k hour battery life, and 12 reticle intensity settings; An adapter plate for compatibility with RMR footprints is included
  • MULTI-RETICLE SYSTEM - This Holosun reflex sight is equipped with MRS to let you select a fast sight picture for shorter distances with a 32 MOA circle with 2 MOA dot; The large circle allows for a hold-over reference and helps guide your eye to the 2 MOA dot; The large ring can be deactivated leaving just the 2 MOA dot for an uncluttered sight picture and increased precision
  • SHAKE AWAKE TECHNOLOGY - Extends battery life by deactivating the optic's LED while not in use; Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred; The slightest touch of the optic instantly reactivates the LED so your Holosun reflex sight for pistol is ready when needed

  • Rugged & versatile
Color: Red 2 MOA Dot & 32 MOA Circle (HE509...
This has really helped my shooting but it does have a learning curve if you’re used to fixed sights. It took a little getting used to however the twin reticle helps me with shots further down range. Have it on my Glock 40 MOS 10mm gen 4. It replaced an older, more expensive red dot. I like the green as it’s easier on the eyes (for me). Mostly I do indoor range target shooting. I have a few other Holosun sights & they’re all good but I like this one best. It’s very rugged, versatile & the enclosure is worthy also, keeps the crap out. I like that I can mount it on some of my other firearms & also can be as usable on a shotgun. ... show more

I have been using this for a while now and love it. I like the green over the red and they say it’s better for older eyes and those who have an astigmatism. Still have the original battery in going strong. I like the choices for auto brightness or setting what you want. I also like the choices of dot, circle, or circle and crosshair. I took a two day class and feel very comfortable using this on my gun! ... show more

Holosun makes a great optic. It is on my duty gun and has made me shoot better. Get one, especially if you are getting older.

  • Nice Tool To Have

I installed this on a new Glock 9–my first pistol. I took a basic shooting course and the instructor helped me align the indicator (I like the dot) for accuracy. This fits nicely into the mounting on the gun and is easily seen when aiming at the target. I’m still in the rookie stage of learning to shoot a hand gun, but I can see where using a gun without a unit like this would make the task more difficult. This one’s a winner! ... show more

Seller shipped a used/returned optic to me. Optic was covered with scratches around the battery compartment, glass and optic were dirty, and I believe also contents from the box were missing.
