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...

by Salvatore Ceraldi, Verified Owner from NC, United States Written on September 27, 2025
This sight is an absolute game changer. I was so against using a red dot until my shooting instructor Convinced me to get one and I will never go back to irons this sight is amazing and worth ever dime.

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.

Great optic for the range and competition

by Jason Bourne, Verified Owner from TX, United States Written on September 14, 2025
I prefer the EPS carry as a carry optic but 507C X2 is perfect for the range or competition. I really like the auto brightness and the solar backup feature. I have had situations where I show up for a match and the battery died. MRS circle dot makes it easy for you to get back on A zone for follow up shots. It’s has an RMR footprint. It’s missing a notch to work as a rear sight, but I don’t miss the iron sights at all.
Pros:
  • Automatic Brightness
  • RMR
  • Solar + Battery Life
Cons:
  • Missing rear sight
Best Used for:
  • competition
  • Range
Would recommend: Yes

Great Pistol Sight!

by B Bax, from MN, United States Written on August 12, 2025
OP has a great selection of items for firearms, and any other optics. All the sites I looked at, no one xplains the width of the site may be an issue, and you'll need some sort of adapter plate.
Other than that, good xperience......
thanks
