The Holosun 407K X2 is an excellent choice for subcompact pistols like the P365X/XL, and based on my experience, it stands out for its reliability and overall performance.
Its rugged construction from 7075 T6 aluminum with an anodized finish ensures resilience without adding excess bulk.
The compact profile is perfectly suited for concealed carry.
The crisp 6 MOA dot allows for swift target acquisition in close quarters situations.
While not optimal for extended range marksmanship, it functions flawlessly for its intended purpose of self-defense.
The 50,000 hour battery life is remarkable, and the convenient side-mounted CR1632 battery tray facilitates replacements without disrupting zero.
The motion-activated “Shake Awake Technology” preserves battery by deactivating when stationary and instantly powers on with slight movement, always ready when needed.
I found the lockable brightness settings, including two for night vision use, make the optic adaptable to different lighting conditions.
The rugged multi-coated glass delivers sharp clarity while reducing glare and maximizing light transmission efficiency.
As expected, it seamlessly mounts to pistols like the P365X/XL using the K footpring, though some models with a four-post mount may require an adapter plate.
In summary, this sight is perfectly tailored for concealed carry and defense, with its swift 6 MOA dot fulfilling speed and ease of use requirements in close encounters, backed by rugged dependability, tremendous battery life, and practical features.
Thought from A Neighbors
The Holosun 407K X2 proved to be an ideal introduction to red dot sights on handguns for me, in particular on my new Equalizer pistol.
Thankfully, it fitted flawlessly on the Equalizer without demanding any supplemental plates or machining work, relieving me of potential complications.
Still, I was let down to discover the optics failed to include the proper screws required for installation.
Given the price point of the sight, this felt like an oversight on Holosun’s part.
To remedy the matter, I picked up some black oxide flat head socket screws in 6-32 size from a neighborhood hardware shop.
While I was constrained to 1/2 inch screws due to availability, somewhat longer options similar to 9/16 or 5/8 inch would have been preferable fits.
The 1/2 inch screws worked regardless, but it is crucial to thoroughly clean any oil residues from the screw holes and mounting slots before using locking adhesive to securely fasten them.
The sight offers a minimal cooperative witness with the standard iron sights.
Though merely about 20% of the front post is visible, it is enough to rely on in an emergency and still offers precise alignment.
It also pairs flawlessly with the inside-the-waistband Crossbreed holster I obtained, furnishing a suitable choice for concealed carrying.
At the range, the 407K X2 impressed with a just right 6 MOA dot and only requisite minor zeroing adjustments to achieve perfect accuracy.
It continued to hold zero admirably through multiple rounds of fire.
I appreciate the side-loading battery tray permitting power source replacements without detaching the optic entirely, and the motion activated feature proves incredibly responsive, confirming the sight is perpetually prepared for immediate use.
What stood out most clearly was how it enhanced my situational awareness through maintaining targeting with both eyes available.
Despite initial annoyance over needing to independently source screws, I would not hesitate to again select this sight.
It delivers outstanding performance as a high-quality, dependable optic.
Conclusion
The Holosun 407K X2 combines cutting-edge technology and durability into a compact optic well-suited for any shooter, whether just starting out or a seasoned veteran.
Its 6 MOA dot, long lasting battery, and innovative auto-activation provide constant readiness.
Constructed to withstand the range yet simple to operate, the 407K X2 flourishes in a variety of lighting with its fully multi-coated lenses.
Adaptable to carry weapons or for the range, its rugged design ensures clear sight pictures when seconds count most.
For those seeking a sight to always have their back without fail, the 407K X2 from Holosun elevates any handgun to elite performance under any condition imaginable.
