I have this sight on a Glock 19, best pistol mounted reddot I've tried and yes it does come in red but the green is better ,,, here is a copied review from the web site >>>>>>>>>>>>>>>>>>
OUTSTANDING OPTIC" AT THIS PRICE POINT!
by Nevadasun -
I'm going to give this optic FIVE STARS. It was truly difficult to find an optic that would meet my criteria. Then came the Holosun HE507c-GR-X2.
I can see green better than red and I prefer a chevron over a dot. With the chevron I have a precise aiming point, I like that much better.
Once at the range, I found the optic to be extremely easy to sight-in. On a sandbag, I checked point of impact at 15yds with five rounds. I adjusted twelve clicks to the right and three up, DONE. I expect many years of use from this quality product.
