    My 509T-RD X2 arrived today and at first glance, where was Holosun’s Quality Control? Upon further observation, the glue was “slopped” onto the glass. I even had glue smudged all on the inside walls of half the optic itself as if they were trying to correct the error. I believe the optic may have been used or repurposed. C&H precision did a great job on their plate as it mounted well to my G19 MOS. I definitely wish I spent a bit more and gone with Trijicon. Instant regret with this purchase.

    I’m a man of few words as such my review will be relatively brief. I bought this optic and an adapter plate for my brand new Walther PDP Full Size 4.5 inch and I couldn’t be happier. Every fits and seems to be functioning great. I’m definitely keeping my business with this company for all my red dot and adapter plate needs.

    Absolute love the 509t…got a fantastic deal purchasing it through C&H and having them mill it directly onto the slide of my 19x, and I will soon be sending the slide off either my G20 or G40 to have the same done….can’t recommend them enough, top quality service all the way around!

    I can tell you that I am so overly impressed with both the Holosun 509-T Red Dot sight and C+H Precision Weapons, that will continue to order my red dot sights and plates from them. Their customer service and quick response to questions are second to none. I think they are making the best plates on the market for Glock MOS slides. Order from this company – you will not be disappointed.

    Robust little optic, blue lens is less drastic than an rmr. my astigmatism hates most red dots in any environment. took a leap on this and there is barely any smearing in dim rooms and none in well lit and sunny spaces. i ordered the chpws 509t v4 plate from big tex and its amazing too. dont hesitate
