Holosun 507C V2 Open Reflex Pistol Sight: HS507C X2 

Holosun Pistol Red Dot

The HS507C V2 delivers Multiple Reticle System (MRS) technology and extended battery life in a robust reflex sight designed for pistols. With MRS, switch between reticles effortlessly—choose the precise 2 MOA dot for accuracy or engage the 32 MOA circle for rapid target acquisition. Better yet, combine both without the hassle of re-zeroing when switching reticles.

Benefit from advanced LED technology that extends the battery life up to 50,000 hours on a single battery. The Solar Failsafe technology ensures your optic operates on ambient light when a power source is unavailable, eliminating the risk of battery failure. The HS507C V2 also incorporates Shake Awake motion-sensing technology, activating the optic with the slightest movement. Its multi-coated lens provides a parallax-free sight picture with unlimited eye relief. Built with durable 7075 aluminum, this optic withstands extreme weather conditions.

Review of Holosun 507c Micro Red Dot Sight


The Holosun 507c MRDS (micro red dot sight) costs less and still maintains quality. An added bonus is that it makes my Glock 19x look even sexier. Bravo Holosun.

I have slowly warmed up to Holosun (I've kept to more well-known brands like Trijicon, Aimpoint, and Leupold). Thus far, from what I've heard and from my personal experience, these optics are tough, and well thought through.

Below I'll cover the important features. Remember to check out the video below to see me run the HS507c  on the range.


HS507c Features and Specifications

  • Low Cost. For under $300 you get the sight and a picatinny mount.
  • Tough Construction. It is CNC machined with 7075 aircraft aluminum. Holy cow.
  • Amazing Battery Life.
    • If left 'ON' at the middle setting, the battery on the Holosun 507c will last 50,000 hrs (5 years).
    • A solar panel on the top of the sight also acts as a fail-safe if the battery is dead.
    • Shake Awake technology turns the red dot off to save battery. If you pick up your gun, the red dot will come on automatically.
    • A negative to the Holosun' design is the battery is on the bottom of the sight. This means you'd have to remove the sight to change the battery. In light of the aforementioned features though...who cares?
  • Multi-reticle System. You can toggle between a 2 MOA dot and a 32 MOA ring (if you are an EO Tech fan, this feature may thrill you).

The Holosun 507c also has features that the other competing sights have such as: waterproof, parallax reducing, night vision settings, unlimited field of view, limited lifetime warranty, etc


This product cannot be shipped outside the USA.

    Great pistol optic

    I grabbed this for my pistol. Works amazing, have only shot maybe 1k rounds with it. Never lost zero and hasn’t crapped out on me. On 4/5 stars because I didn’t get the rail mount with my purchase; but again I bought it for my pistol.
