Holosun 507K-GR X2 Green Dot Sight

My eyes just seem to pick up the green dot much faster. Mounted perfectly to my Sig P365X Macro. Super fast shipping. Thanks

great compact sight, I prefer the green dot over the red. thought I would never use the dot and circle, but actually growing on me. Helps acquire the sight a bit quicker.

The Holosun Green Dot Sight looks outstanding on my 43X, and has performed flawlessly after sighting it in. PRIMARY ARMS had the best price available, and shipping was blazing fast!

I have a more expensive Trijicon RMR red dot on my Walther PDP 9mm, but since then, I have purchased 2 Holosun 507Ks for the approximately what I paid for the Trijicon alone. I am totally satisfied with the pricing, the clarity of sight picture, the multiple reticle choices, the Shake Awake function, the fine manufacturing, the warranty, and most of all, I love the right side battery compartment, so you don't have to remove the red dot from the gun to replace the battery. You can't go wrong with one of these!

The reticle is very crisp. Not much blur with astigmatism. The adjustable dot Is a nice feature as well. Time will tell with how long it holds up. Mounted to agency g43 slide. No overhang. Perfect fit.

This is the second Holosun 507 I’ve bought and both meet all expectations. PA is also top notch. Always getting order out promptly.

The sight is everything that I thought it would be. My eyes work better with the green color and the reticle and center dot makes it easier to focus quicker and on the target. I do recommend this sight for old facts like me.

I have this on a Beretta APX A1 Carry since the optic plate I got for registering it fit this model. Typical Holosun quality, great optic, looks good, and I really like the packaging.

All - I received my 507K-GR in the mail, after install was not impressed. The optic in the sight window would just disappear, circle got distorted (fatter than it should have been), lost clear edges, took up to 45 secs to light up if it went into sleep mode, wouldn't adjust for brightness etc. I slept on it and thought, I'll pull the battery out to reset it. Pulling battery tray completely changed the optic. Works flawlessly! This is only day 1, but for me the first instruction needed to say remove retaining screw and pull battery tray out, reinsert battery tray and retaining screw. Everything is as advertised. I can lay the gun down for 10 minutes (goes into sleep mode) and see optic is off. Just "touch" the gun and it lights up! Things are looking up! Giving it 5 stars because sometimes you got to get things on track.

Holosun's 507Kx2 is for smaller handguns, but it is an amazing optic. The option of dot, circle or circle-dot allows for the perfect reticle choice. I am liking the 32 moa circle, but for extreme accuracy will switch to the 2 moa dot.
