Most Helpful Positive Review Great sight on Sig P365XL
I love this thing. Bolted right onto my Sig P365XL everyday carry pistol (with its optics cut slide) in just a few minutes, needing a 5/64" hex wrench to remove the Sig rear sight. Small, fits very low, protrudes less than .80" above this slide. I prefer the default reticle, dot with circle, for spe...

Most Helpful Negative Review CHECK OPTIC FOR POTENTIAL ISSUE
If the unit is in lockout mode, turning the unit off by pressing both the "+" and "-" button at the same time will prevent the unit from turning back on until the battery is removed and re-inserted. I had it happen to me once but chalked it up to a dead battery, but after reading the other reviews, ...

Holosun HE507K=GR X2

by John, Verified Owner from NC, United States Written on November 11, 2025
Absolutely love the Holosun HE507K. This is the second purchase of the HE507K. I built two 1911's and had the slides milled to accept the HE507K and couldn't be happier. The HE507K is a high quality, reliable sight. It has an impressive battery life. Tough as nails construction and adjustable features. I have the Holosun SCS-M-GR

Great optic at a great price!

by JB, Verified Owner from AL, United States Written on November 10, 2025
This is my 3rd Holosun. My other 2 have a combined total of 18,000 rounds and have worked flawless. I cant say enough good things about their optics. My only con would be that the MRS (32 MOA Circle) isnt perfectly aligned (up,down,left,right). That being said, the dot itself is always dialed in..once you have zeroed your optic. Also, they will fix the misaligned cirlce reticle, if you're willing to ship it to them to have it fixed (free of charge). Their customer service is lights out as well! For the price...im still giving them 5 stars. Get ya one...you wont regret it.
Pros:
  • Price
  • Customer service
  • install easily
  • compatability
Cons:
  • circle - dot reticle alignment

Great red dot

by JM, Verified Owner from LA, United States Written on November 8, 2025
This is my third holosun red dot, I love them. The shake to wake is awesome, would have given 5 stars but I can’t seem to figure out if this has an “auto brightness” setting or not. My other holosuns do.

Holosun HE507K-GR X2 greendot Reflex sight

by Bubbinator, Verified Owner from AL, United States Written on October 17, 2025
Been searching for a Green Dot sight to replace the Sig Romeo 0 that came on my Sig 365XL. Caught the sale on Optics Planet and + discount and Bucks couldn’t resist! Arrived very quickly and fit perfectly on my 365XL. Like the reticle options and it was almost perfectly zeroed right out of the box. Highly recommend this product.

by RugerFan4Life, Verified Owner from LA, United States Written on September 13, 2025
Small footprint, comes with 3 sets of mounting screws with thread lock. Motion sensing activation is nice for extending battery life. The multiple reticle choice is nice to fit what works best for me to achieve quick on target sight. Only thing I think it needs is a dust cover for when not in use or being stored.
