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, ...

Excellent Optic

by Kirk, Verified Owner from PA, United States Written on December 12, 2025
Easy install & works great. I love this optic. I have order 3 more since I got the first one. Easy for my old eyes to see. The 32 MOA ring with the 2 MOA dot is the perfect combination. I would definitely recommend this optic!

Great green dot optic.

by Kansas Randy, Verified Owner from KS, United States Written on December 8, 2025
I can't express how much I like this green dot-circle optic. It is small, tidy on my Girsan baby hi power, very bright and it was easy to mount. Second Holosun I have purchased from O.P. Shipping was fast and painless. Recommendation...put the sight adjustment tool on a loop of paracord and wear it around your neck, so you don't lose the small black thing out in the yard like I did. I love the sight, but Holosun is stingy with their replacement tools.

Small red dot for EDC

by Simon, Verified Owner from NV, United States Written on November 22, 2025
I had a doubt about adding red dot to my P365. It was supposed to be small for every day carry and adding accessories would not be desirable for the purpose. I thought that I would try and added HE507K-GR-X2. The installation was straight forward. I have it cowitnessed with the iron sights and it was not difficult too. At the range, I found it a lot easy to shoot the target. Some say that it is hard to find the dot and I was wondering what it was about. However, I found it easy. Simly speasing, if you can use iron sights, you will see the dot real easy. I recommend this product.
Pros:
  • Easy Mount
  • easy to install
  • easy to use
Cons:
  • None
Best Used for:
  • EDC & defense w/ training
Would recommend: Yes

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
Would recommend: Yes

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.
