Most Helpful Positive Review A high quality red dot sight
This HS 507 holosun is probably my favorite red dot sight and I own quite a few I have the Romeo one sig Sauer vortex venom and the vortex viper I own probably more vortex venoms than any other site and it is a good site but it does not compare to the Holosun. I shoot a lot of AR500 steel targets pa...

Most Helpful Negative Review Broken after 293 rounds.
I zeroed the optic, it was shooting dead on once zeroed. Shot a some to get use to it, then shot the haley strategic venti 100 drill. On the last mag of the drill I took a shot and after recoil I couldn't see the dot. The dot moved so high in the glass you cant see it. I tried adjusting it down but ...

Red Dot Disappeared

by Chris G., Verified Owner from MO, United States Written on December 15, 2020
Less the 10 rounds before the red dot disappeared. As I continued shoot it would occasionally flash across the glass at blinding full brightness. I have exchanged for the X2. I was so excited and so disappointed.
Pros:
  • None
Cons:
  • Stopped working after 10 rounds
Would recommend: No

Great micro optic

by Joe, Verified Owner from KS, United States Written on December 14, 2020
Purchased if for a Canik Elite Sub Compact, fits right on and so far has held its zero after everyday carry for a few months and an accidental drop. The multi reticle is pretty good, allows for quicker accusation of the reticle compared to regular dots ive ran before.
Would recommend: Yes

Awesome optic!

by Josh b, from MI, United States Written on November 27, 2020
Great optic! Rugged and compact. Great features! Love the brightness settings and option for three different reticles. Easy to zero and holds zero plus the battery door on the side makes for easy changing

So far so good

by Stone, from CA, United States Written on November 27, 2020
Mounted this on my 1911 style pistol and it has been solid thus far. Held its zero after just over 1k rounds and I’ve used the dot with good hits on targets all the way out 128 yards. The small profile makes this a good fit for my concealed carry.
Best Used for:
  • Concealed carry pistols
Would recommend: Yes

HS507K on 43X

by Chris, Verified Owner from TX, United States Written on November 25, 2020
It took a while to get mine from OP then I had to leave it with my gunsmith for a few weeks so he could mill my slide and mount the sight. That said, it was well worth the wait. It fits the weapon perfectly, low enough where I can co-witness with the iron sights and flush with the sides of the slide. As with the other Holosun red dot sights that I have, it allows for faster target acquisition and more accurate shots. I’m looking forward to changing the battery using the side mounted battery tray. This beats the heck out of having to remove the sight from the slide to change the battery. Overall, a great addition to my favorite carry weapon.
Pros:
  • Design, functionality
Cons:
  • None, except the wait to get it.
Best Used for:
  • Conceal Carry
Would recommend: Yes

Great RDS for a P365XL Defensive Carry

by Will, from WA, United States Written on November 22, 2020
This sight fits super well and the reticle changing options are nice. The published battery life is great but I can't speak to the reality of that yet. Really like the switch locking feature to prevent accidental switch actuation,
Pros:
  • Small & practical for carry
Cons:
  • None
Best Used for:
  • carry , defense
Would recommend: Yes

Great single stack red dot

by Z, from AL, United States Written on November 21, 2020
If you can snag this one it has the large buttons on the side. The 507kv2 will have small buttons. It fits perfectly on my M&P Shield. I prefer the 507 large circle for close range and the 2 moa dot can be harder to pickup on the smaller window.
Would recommend: Yes

Almost love it

by me, from AZ, United States Written on November 20, 2020
I got my slide milled on my P365 for this sight. The only thing that I'm not happy about is that the built in iron sight is useless. It also makes the standard irons useless. It comes down to the depth of the slide cut. I got my slide milled from Mapleleaf, here's what they said.

"The P365XL is indeed a deeper optic cut at .180” deep. Unfortunately we are only able to machine regular P365 slides to .125” deep. Going any deeper would cut into and compromise the drop safety mechanism in the slide."

I also contacted Sig Sauer about offering a standard P365 slide that is configured and cut just like the P365XL slide with the rear sight plate. They were not interested.

4 stars because I cannot use the built in iron and my stars irons can't be used either.
Pros:
  • Looks great
Cons:
  • built in iron sight useless
Would recommend: Yes
