Let’s get to it!

Holosun HS507K-X2 Review
Holosun HS507K-X2 comes neatly packed with four supporting accessories and a manual. These include:
- 2 Screw Sets
- 1 CR1632 Battery
- Allen key
- Cleaning Cloth
The red dot itself is pretty tiny in size. It measures only 1.6 inches in length, 0.98 inches in width, and 0.95 inches in height. At a glance, you will be able to tell that it’s designed for sub-compact guns.
You can easily mount it on your pistol without purchasing any extra stuff. Here’s a quick video tutorial about how to install a Holosun 507K on a SIG P365XL to help you get an idea. The installation process is similar to all other guns.
The interesting thing to note here is that this tiny little fellow can bear the roughest of treatments. Its straight-cut, aluminum frame gives it a sturdy build. Plus, the rounded edges of the thick lens distribute the stress on the lens enough to protect it from any damage. It adds to the durability.
The lens is also multi-coated. It allows greater transmission of light and hence better vision. And it also minimizes glare, so you won’t find yourself struggling for a clear vision under bright light.
It comes in two colors, including:
And once it’s mounted, it almost appears to be the part of the pistol. Being lightweight, it doesn’t add to the gun’s overall weight and keeps handling as light as possible.
What’s more, it’s super easy to change the battery of this red dot sight, thanks to its easy battery access. Just use the Allen key with the red dot sight to access the side battery tray. Once it pops open, replace the old CR1632 battery with the newer one.
However, you won’t feel the need to change the battery for at least 50,000 hours of use. And that’s probably equivalent to several hunting sessions for 2-5 years if you’re a hobbyist shooter.
When it comes to aiming, the Holosun 507K will delight you. The smaller window size ensures faster target acquisition. Plus, it features a combination of 2 MOA with 32 MOA. Hence, you can expect admirable accuracy for long distances.
Holosun 507K is one of the few mini red dot sights with two buttons. Although the presence of two buttons was largely questioned by those accustomed to the traditional dial or one-button design, we find this super handy.
Holosun HS507K-X2 comes with ten daylight and 2-night vision settings. You can switch to your desired settings via these two buttons without shuffling through all 12 settings.
Every red dot sight manufacturer comes up with newer innovative technologies to make lives easier and stand out in the market. Holosun’s most popular technologies are as follows:
- Shake Awake Technology
- Lock Mode
- Solar Failsafe
From amongst these, Holosun 507K-X2 comes equipped with the first three.
Shake Awake technology basically refers to an integrated motion sensor. When the pistol is not in use for shooting, the sight enters a sleep mode wherein the sight remains active, but the illuminated red dot on sight is powered down. As the pistol remains untouched and motionless for days and weeks, this feature keeps the battery from wasting away. Thus, in this way, your pistol with its mounted red dot sight is always ready to get into action. And the battery is preserved simultaneously.
Lock mode is another useful feature. It keeps the user from pushing any of the sight’s buttons accidentally. As for multi-reticle technology, you can use it to toggle between 2 MOA and 32 MOA. You can even use it to bring both together and aim at your target more effectively.
Who’s it for?
Technically, anyone who wants to use this super capable HoloSun HS507K-X2 can use it. But it’s best recommended concealed carry gun applications. So, this is for you if you carry a gun for self-defense purposes.
Now, if you’re wondering which compact guns would be compatible with HoloSun 507k-X2, then here’s a list:
- Springfield Hellcat
- Glock 48
- SIG P365XL, etc
Overall, Holosun 507K-X2 is an excellent pick for compact gun owners. It’s phenomenally functional and accurate for its price. The ease of use makes it a perfect choice for frequent users or hobbyist shooters. When you’re on the run, you’ll find this red dot sight smoothly complying with your commands and syncing with your moves.
We wouldn’t recommend it to anyone who’s just begun exploring red dot sights and pistols. As functional as it is, this red dot sight is also a little complex for new learners. Apparently, Holosun’s customer service is not to rely on, so it’ll be a waste of money if you buy and can’t solve an issue that arises. So, it’s best not to risk it!
