Holosun 507C X2 Pistol Red Dot Sight
The Holosun 507C X2 brings massive capability to your optics cut pistol, with long and reliable battery life and a circle dot reticle. This red dot sight uses the Trijicon RMR mounting standard, which is commonly available on optics-ready pistols, such the Glock 19 MOS. The 507C X2 features excellent reliability, with 50,000 hour battery life, Shake Awake, and Solar Failsafe.
The Holosun circle dot reticle also makes getting on target fast and easy. The 32 MOA circle helps you get on target after drawing from your holster, so you can make fast, accurate shots. With the 1 MOA click adjustment, you can effectively zero your pistol precisely for its effective range. Plus, it’s tough enough to perform reliably for thousands of rounds, rated for up to 5000 G’s from recoil.
Red Dot or Green Dot?
Holosun makes this sight with a red emitter, or a slightly more expensive green emitter. As for which one is right for you, it depends. Both models have the same features and incredible battery life, though some shooters prefer the green dot because it catches their eye faster than the red reticle.
One thing to consider is your shooting environment. If you have a lot of green in your background, the red version will provide you with better contrast. In arid environments with reddish soil, the green reticle will stand out more. It depends on your eye and your situation; but in our experience, it’s down to personal preference: you can’t go wrong.

After closing out our session, I had another question about the AR15 9mm charging handles. So I call the 800 number and low and behold. I got the same person i was engaged with during the online chat. I'm very impressed with their service attention to the customers as well with this product. I will buy this in the near future and change out my red dot for gren dots as it pleasing to these old eyes 👀
