Most Helpful Positive Review RMSc not RMR
This is a great sight for the money especially when comparing it to Trijicon's new RMRcc at twice the price. Compact, durable, and great sight picture for a small optic. It's neat to have the dot, circle dot, and circle as options - however I do prefer just using the dot. I am writing this review to...

Most Helpful Negative Review Unable to Zero
The red dot was so far to the right out of the box that it reached it's mechanical limits of adjustability. This is my second Holosun 507k as I had the V1 and it lasted 10 rounds. I contact acted Holosun's Instant Messenger on Facebook and had the rudest customer service experience EVER! Luckily Opt...

Good sight, problem with mounting

by SigShooter58, Verified Owner from TN, United States Written on November 5, 2024
It is a good sight but the mounting screws were too long for my Sig Sauer P365 TACOPS 2X.

No Complaints

by AT, Verified Owner from LA, United States Written on October 26, 2024
I haven’t put this thing through the wringer; I’ve only zeroed it. However, it was perfect right out of the box. Easy direct mount (no plate needed) on my P365 Macro X. Perfect zero at 25 yards and good at 5, 10, 15, and 20. I’ve had multiple Sig and Holosun red dots and Holosun is much better than Sig IMO. All of my Sigs have failed at some point but no failures on the Holosuns. Plus, the shake awake technology, external battery access and different dot options are better than Sig. People bang on Holosun because they aren’t American made but neither are our iPhones yet everyone has no problem buying those.

Good Optic

by shadow, Verified Owner from VA, United States Written on October 19, 2024
I put this on my carry gun and it is small enough not to feel in my waistband. It was easy to mount and the shake awake works great. I have not had it long so I can't say if the advertised battery life is true. The only note I have is that the bright settings are really bright and not that practical.

by moa, Verified Owner from CA, United States Written on October 3, 2024
We all know how hard it is to be really accurate with iron sights. I had no idea how easily I could aquire and shoot the center of the target! And this reticle is amazing! 2 moa dot for precise target shooting, circle and dot for easy targeting!

best bang for your buck

by Miller, Verified Owner from CA, United States Written on September 25, 2024
Holosun puts out some high quality, reliable, cost friendly (not cheap, but not overly expensive) optics. I have holosuns on 4 different hand guns and this is my 3rd 507k. The 507k is my favorite, it’s been 100% reliable and has stayed zeroed since i first mounted it.
Pros:
  • reliability
Cons:
  • None
Best Used for:
  • carry, competition, home-defense, range usage

HS507K-X2 Red Dot

by Nupe1911, Verified Owner from CA, United States Written on September 17, 2024
Fast Shipping. I received my package one week after ordering. Depending on your firearm, it was very easy to install myself (YouTube tutorial). A friend had to send his sig in to manufacture to modify his slide to attach HS507. Again, YouTube tutorials are available to zero in your red dot. Very happy with my purchase.
Pros:
  • Instal quick and easy. Perfect fit.
  • Shipping and price
Cons:
  • Make sure you get the right model .

Great sight at a great price

by caribou60, Verified Owner from VA, United States Written on September 16, 2024
Put this on a new Taurus TX-22 T.O.R.O. So much confusion these days about optics footprints. Taurus says their optics cut is RMSC. Holosun says this sight uses their K footprint. All I know is it fit perfectly, tight and flush, no gaps. The features are typical Holosun, shake awake, side battery, three reticle combinations, 12 brightness settings. Looks and works great on this pistol. My third Holosun, one on a PCC, one on a 12 gauge and now this one. I think their products are basically the best bang for your buck. Got this one from Optics Planet on a "Super Savings" sale at a great price, basically about $50 lower then anywhere else. Couldn't let that pass, processing and shipping was quick and uneventful. Great purchase all in all!
