I’ve been a Holosun consumer for a long time. I started shooting PCC when USPSA first allowed this platform. I went from a Eotec to Holosun and now I have many Holosuns on my pistols and long guns with no issues. Holosun has been very innovative offering green dot sights a long time ago and changing battery is easy and accessible without removing optic. I’m older and green dot sights work for me. Freedom Gorilla is awesome making it easy to find the right optic with the “optics by platform” menu which allowed me to find the right optic for my Kimber2K11. The 407c X3 is exactly what I was looking for. I wanted a large window but the Holosun comp was too large. The 407X3 window is generous enough without being too large and is slightly bigger than my 508t. This allows for faster sight acquisition, keeping eye on the dot during recoil and good peripheral vision. I would have considered Trijicon a long time ago but they didn’t offer green dots and battery access is an issue. They are slow coming up to speed. I’m well satisfied, thank you Freedom Gorilla you guys crushed it !!!
