Highlights
- Multi-Reticle Flexibility
- Shake Awake Technology
- Side-Mounted Battery Tray
- Durable Aluminum Construction
- Compact and Lightweight Design
The Holosun 507K-GR X2 Green Dot Sight is a compact and reliable optic, and I, found it to be an excellent choice for subcompact pistols like the P365X/XL.
Its green Multi-Reticle System (MRS) allows seamless switching between a 2 MOA dot, a 32 MOA circle, or a combination of both, offering versatility for quick target acquisition and hold-over references.
The green reticle is crisp and highly visible across different lighting conditions.
One of the standout features is the Shake Awake technology, which extends battery life by deactivating the LED when idle and instantly reactivating it with minimal motion.
This ensures the optic is always ready without manual input.
With an impressive 50,000-hour battery life using a CR1632 battery and a side-mounted tray for hassle-free replacement, it’s built for reliability.
The optic is crafted from 7075 T6 aluminum, combining durability with a lightweight design which is perfect for concealed carry.
Its 0.58 x 0.77-inch window provides a clear sight picture without adding bulk.
The Lock Mode prevents accidental setting changes, while the 1 MOA click adjustments for windage and elevation ensure precision with a travel range of ±30 MOA.
It also includes 10 daylight and 2 night vision brightness settings, making it adaptable to various environments.
While it mounts directly to pistols like the P365X/XL, it requires an adapter plate for slides with a four-boss interface.
The small window size might take some getting used to for those familiar with larger optics, but it’s ideal for subcompact applications.
As someone who values performance and durability in firearm accessories, I highly recommend the Holosun 507K-GR X2.
Its combination of Shake Awake, MRS, and robust construction makes it a top-tier choice for anyone seeking a dependable and compact reflex sight.
Hint, If you prioritize a larger field of view, versatility, and additional features. The 507C is designed for full-sized pistols, rifles, and even shotguns, offering a larger window that provides faster target acquisition and better situational awareness.
Its multi-reticle system allows you to switch between a 2 MOA dot, a 32 MOA circle, or a combination of both, adapting to various shooting scenarios.
The solar backup feature ensures the sight remains functional even if the battery dies, making it incredibly reliable for extended use.
If your firearm can accommodate a slightly larger optic, the 507C is the better option for enhanced precision and durability.
Thoughts From A Neighbors
The Holosun 507K-GR X2 is an excellent red dot sight, and I, am genuinely impressed by its performance and design. The solid frame is robust and inspires confidence in its durability.
While I don’t plan to subject it to a torture test, I believe it could withstand even unreasonable handling.
The side-mounted battery tray is a standout feature, setting it apart from other red dots in this size category.
The ability to replace the battery without removing the optic, and thereby avoiding the need to re-zero is a huge advantage.
While the stated battery life of 50,000 hours is impressive, I can’t personally verify it yet, but my current battery has lasted several months and is still going strong.
I love the 2 MOA dot for its precision, but I’m still undecided about the 32 MOA reticle.
However, the versatility of cycling between the dot, the reticle, or both with a simple button press is fantastic.
It lets me adjust to my preferences or shooting scenarios effortlessly.
The brightness settings are impressive, ranging from extremely dim to very bright.
Personally, I find the brightest setting too intense even in sunlight, while the dimmest is almost invisible.
There’s plenty of range to find the perfect setting for any environment.
Although it includes night vision settings, I haven’t tested those yet.
This optic far outshines the Romeo Zero it replaced. I was so impressed that I bought a second one for my wife, who switched from iron sights to this Holosun.
I switched from a different red dot, and we’re both extremely satisfied.
The Holosun 507K-GR X2 is reliable, versatile, and well worth the investment.

Its robust construction, innovative features like the side-mounted battery tray and Shake Awake technology, and exceptional 50,000-hour battery life make it a standout choice for subcompact pistols.
