Holosun HS507K-X2 Compact Pistol Red Dot Sight - ACSS Vulcan Reticle

Running it on an off duty csxe. The Vulcan does help your brain auto focus the dot into your eye sight. Not as needed if you actually practice a ton but if you don’t shoot often and or if you shoot from a variety of positions and not statically it really is super useful. Glass is clear with no noticeable tint and housing seems sturdy. Gets banged up a little here and there and so far no issue. Too new to comment on battery life but a fantastic product all around.

I bought two of these to install on Glock43x and Sig P365 380. I mounted sights using screws provided and took guns to range to put first rounds thru. Both guns had stovepipes and jammed. The Sig malfunction every couple rounds. I am a Sig and Glock armorer so after trying some standard things - the only thing these two guns had in common was Sight. I remember screws causing problems with FTF's and extractor issues- I removed the right side (extractor side) screw on each gun and filed down about 1/16 or so. Re- loctite and headed to range- no malfunctions either gun- full mags; partial mags, 200 rnds each gun. Hope this might help others if you have problems like this... Primary arms need to check screw specs.... Love this sight!

I always seem to loose the red dot when I'm shooting (because I don't practice enough). The set up with giant ring surrounding the red dot makes it super easy locate the dot. Keeps it's center with easy to replace battery.

With a lot of training should be able to draw and consistently put pistol on target without the assistance of the outer circle. That said, this system makes it foolproof

It works great so far and no issues

Installed the plate, installed the sight and got it zero with no issues. Shake awake is nice and the MOA ring will guide you to the dot immediately. See how it holds up over time. G19 G5 MOS

I took my Glock 43X in to have this Holosun red dot put on. But I was told by the gunsmith that apparently Holosun had upgraded this red dot and failed to mention this to Glock owners. I'm going to contact Holosun about this, but because this was an unexpected cost and delay, I'm giving it a low rating.

This is a great upgrade for those that are using this size RDS. The smaller window can make it harder to initially find the dot when doing a quick draw or reload.I have been waiting for Holosun to make this Vulcan version in the 507K size and they finally delivered! The outer ring is not a solid ring, so it doesn't look as neat as it does on the larger version, but I have read the dotted outer ring helps save on batter life. So far, I find it works great as advertised. I also am glad they went with the dot instead of the center inverted-v. Perfect for my smaller everyday CCW.EDIT: this listing says it's a 1 MOA dot, but it's really a 3 MOA dot with a 230 MOA outer ring. Those specs are printed in the instruction manual inside the box.
