Adapter plate that allows you to mount Holosun 509T or 509ACSS to Glock MOS.
- Allow the red dot to be mounted in the lowest possible configuration on the slide to reduce height-over-bore, and easy of co-witeness with iron sights.
- Made of high-strength, Grade 5 (Ti-6Al-4V) titanium. It is several times stronger than low-carbon steel while being lighter at the same time to help reduce the influence on slide cycling.
- Sandblasted for a non-reflective finish, and electro-anodized to a grey color, other colors available at an additional cost.
- I can also Cerakote it in Gen 2, NIR-compliant, Graphite Black if you really want it to be black at an additional cost and a few days of lead time.
- Adapter plate for 509T weighs 10g and 509ACSS weights 9g.
- 2x M3-0.5x8mm alloy steel Torx screws supplied.
* 509ACSS version will also work for 509T, but there will be a gap in front of the red dot.

Holosun 509T Adapter Plate
Ordered this to mount the 509T on my Glock 45. They were quick to respond to questions prior to my purchase and got it out the door quickly after I pulled the trigger on it. The plate seems to have held up well and maintains zero after multiple trips to the range and getting banged around in my holster. I like that it’s made from titanium, keeping the weight of the slide with the optic on it closer to the factory weight. I would recommend this plate.

Awesome company
I purchased this without realizing it was not compatible with my specific firearm. 100% my fault but their customer service went above and beyond to help me out. I’ll shop here in the future.
