desertcart.com : HOLOSUN HE509T-RD X2 Reflex Red Dot Sight for Pistol - Durable Shake-Awake Parallax-Free Enclosed Handgun LED Sight with Multiple Reticle System & 12 Brightness Settings - RMR Adapter Included : Sports & Outdoors

Review: Perfect Red Dot for My Glock 47 - I recently mounted the Holosun HE509T on my Glock 47, and I couldn’t be happier with the setup. The installation was straightforward, and it fit perfectly without any issues. The red dot is bright, clear, and easy to acquire quickly, which makes target transitions smooth and fast. I’ve used it for both range sessions and dry-fire practice, and it’s incredibly reliable. The sight holds zero perfectly, even after repeated shooting, and the battery life is impressive. I also appreciate the rugged build—it feels solid and durable, exactly what I want on a handgun. If you’re looking for a dependable, high-quality red dot for your Glock, the Holosun HE509T is an excellent choice. It’s made my shooting more precise and enjoyable.
Review: Great optic - Love it, it's on my FN 545 tactical, and is my main carry gun.

## Questions & Answers

**Q: What’s the pic tail mount for this?**
A: It is a proprietary mount - does not fit the standard rail (nor does it fit the ACRO rail).  It does come with an RMR plate, so it can be used on any mount that has a RMR footprint.  There are also 509T specific mounts available.

**Q: Is there a dovetail adapter for a glock 19 for this sight?**
A: Yes, I suggest C&H Precision Weapons. They make the best adapter plates. Fit tight perfectly & they send high strength screws & proper threadlocker.

**Q: Works with shadow system but requires a aftermarket adapter plate. Shadow Systems Aftermarket Slide to Holosun 509T (STEEL) SKU: SHDWSYS-509T-ST?**
A: I can't do the video thing, but I could send (attach) a photo of the cut.  The 509T is titanium not steel; I assume you mean steel adapter plate?  Anyway, I'm sure CH Precision has what you need (their plates may well be here on Amazon).  If your aftermarket slide is cut for this RD you don't need any plate--that's why I wanted to send a photo.

**Q: Is it compatible with walther ppq q4?**
A: Any enclosed optic using a cross bolt is not directly compatible. It does come with a plate.

### ⭐⭐⭐⭐⭐ Great optic
*by A***R on January 21, 2026*

Love it, it's on my FN 545 tactical, and is my main carry gun.

### ⭐⭐⭐⭐⭐ Rugged & versatile
*by M***N on April 23, 2025*

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.
