Holosun 507K-GR X2 Green Dot Sight

This is the perfect sights for the 43x mos in my opinion. The size fits perfectly, the green dot is amazingly easy to pick up and it is small enough for EDC.

Installed on a Sig P365 slide, easy installation and just the right size.. I like the reticle options and the green is easier to see than the red dot sights.. I got a good deal too ! Thanks !

Pulled out my 2 screws and replaced with the 2 tapered screws for plate mount and it truly did not need adjustments, first time I have ever mounted any optic and not had to sight in.

The optic never has held zero for me. I've tried everything and don't know why it wont hold for me. I probably got a bad one.

Excellent optic with a lot flexibility in changing reticle (dot, circle, both). Very fact acquisition on target due to circle and dot combination. Fits perfect on SIG P365

Recently purchased and installed the Holosun 507k on an optics ready S&W 22 magnum pistol. Easy installation, although had to use my own shorter screws. This is a great red dot because, among other things, it has more than just a dot. I use the circle reticle mostly, and switch to the dot for extreme accuracy. Terrific for older eyes.

Sight has great clarity and I like the green dot. One negative is that I maxed out on elevation adjustment zeroing for 15 yards. It's zeroed but I would not be able to make any additional adjustments if needed. Overall a great sight for the money.

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.

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.

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.
