Great optic
Bright dot, good features, and an affordable price. Green is better for my astigmatism but still not perfect.

Fantastic sight
I have had a few 407K/ 507K by Holosun over the years and they are by far one of the best sights for the money. It is so much simpler than the more expensive sights like my RMR. Being able to swap the battery without removing the sight completely is a HUGE benefit. I have daily carried my 407K for years and never had an issue. The aluminum is strong so I have no worry about breaking it. It fits well and holds zero. I wish that they would stop raising the price but it punches well above its weight cost wise. ... show more

Works OK
Held zero well, but I went back to iron sights eventually. Didn’t like looking through a small window, I prefer I wider field of view. Stopped using red dots completely on my pistols. Hope this helps. Aloha.

Best optic for the money.

Have three of these on three of my pistols. Clear visibility, user friendly, and once sighted in very accurate. Very affordable. Sleep mode just shake and shoot.
