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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Red Dot for My Glock 47 *by J***S on August 30, 2025* I recently mounted the Holosun HE509T on my Glock 47, and I couldn’t be happier with the setup.

Otherwise, perfect red eye. Holds zero, doesn't flinch if you use it as the rack slide. sight it at 15 or 20 meters, or yards, go home, sleep well. This thing self charges with sunlight, so spend time outside with your gun. Day at the range, less batteries. Clearly, bullets cost more than batteries. Adjust to your finances. If you cannot afford bullets or batteries, you are in the wrong review. But possibly have the right gun? Turn yourself in. PS. Using this with an M&P 10 MM Performance Center pistol. Cast your hate aside, this works. ## Frequently Bought Together - HOLOSUN HE509T X2 Reflex Pistol Sight - Shake-Awake Parallax-Free Enclosed Sight with MRS - RMR Adapter Included - Red/Green - DPP Titanium Mount/Adapter Plate Compatible with Glock 17 19 MOS Holosun 509T - Streamlight 69260 TLR-1 HL 1000-Lumen Rail Mounted Strobing Tactical Weapon Light with Rail Locating Keys and Lithium Batteries, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/375229399-holosun-509t-x2-series-reflex-sight-shake-awake-parallax-free](https://www.desertcart.us/products/375229399-holosun-509t-x2-series-reflex-sight-shake-awake-parallax-free) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-14*
