Excellent Optic

by Jeremy, Gear Expert from IL, United States Written on July 28, 2021
I was skeptical about putting a miniature red dot sight(MRDS) on my handguns when they first came out. The process and price at the time seemed like a hassle. These days however its easy to find a milled slide or a local gunsmith who can mill your factory slide. There are plenty of options to choose from when it comes to MRDS options. Having seen plenty of other shooters use Holosuns on their handguns and carbines I decided to give them a chance. A year later I have Holosuns on all my pistols including a Glocks, Shadow Systems, Staccatos and Langdon Berettas. For the price you pay you get a sturdy red dot with awesome battery time, good glass, and reticule options. I've used them in several shooting courses where they have been banged around and they still held zero. If you're looking to jump on the MRDS bandwagon Holosun is an excellent choice that will not break the bank.
Most Helpful Positive Review Holosun is awesome
Shame on Trijicon for suing Holosun. They make an overall better product at a lower price. Shake awake, auto dim, "forever" battery life, side door for battery replacement. It is a great reflex sight at a reasonable price.
Most Helpful Negative Review Great Optic.......When it works
I wanted to give this a good test before I reviewed the sight. I am going to make a very long and frustrating process short. I ordered a 507c, and had it about 3 months. Put about 5-7 hundred rounds through my custom Glock 17 and the center dot went out. All I could get was the ring. Contacted Holos...

So Far I'm Happy

by JAC, Verified Owner from NJ, United States Written on November 25, 2025
I have only used this sight a few times so I am still growing accustomed to it. The sight mounted easily and windage was dead on. I did have to raise the elevation a few inches at 25 yds. This only required 3 shots from the bench. I like the sight options and clarity. I will add an update after a few bullseye league relays.
Pros:
  • easy to mount and zero
  • Accessible battery location
Cons:
  • None
Would recommend: Yes

Slide Cut is a Hassle

by jeff, Verified Owner from CA, United States Written on September 20, 2025
I only returned this great optic because the time and cost of machining my existing slide was too much of a hassle.
Instead, I bought the Holosun SCS-MOD & the "Extra Slide" from Glock, which comes with the MOS cut already.
