Description

The Holosun 407K / 507K-X2 Series is a compact open reflex sight tailored specifically for subcompact and micro-compact pistol platforms. Designed with concealed carry and everyday use in mind, both delivers dependable performance in a streamlined and lightweight form factor. 407K-X2 features a crisp 6 MOA dot while 507K-X2 features 2MOA/32MOA Circle Dot powered by Holosun’s efficient Super LED, offering up to 50,000 hours of battery life on setting 6. Shake Awake technology conserves battery by powering the sight on with motion and turning it off when idle. Lock Mode—first introduced in Holosun's law enforcement models—prevents accidental changes to settings, making it an excellent choice for defensive carry. The "K" series is built with a rugged 7075-T6 aluminum housing and is IP67 waterproof-rated for durability in harsh conditions. It includes a side-mounted battery tray for quick and easy replacement of the CR1632 battery without removing the sight. With 12 brightness settings, users can fine-tune their aiming experience for any lighting environment. Utilizing Holosun’s proprietary “K” footprint, the "K" series is a direct fit for pistols like the SIG P365X/XL and others designed for micro red dots, though it may require an adapter plate for some slide interfaces.

    • Seems Like a Fantastic Product Thus Far!
Color: Black (Green) Reticle type: Multi-Reticle
I just got a new Sig Sauer P365X Macro. I wear cheater glasses, but no prescription, and was having a very hard time seeing the iron sights (even though they are neon colored) on the X Macro. With this optic installed, I can see it perfectly clear with/without cheater glasses (the 32MOA + 2MOA circle and dot combined, standalone circle, and standalone dot as well). I can't comment on how well it works, or much of anything else yet, because I have not had a chance to use it (other than using a barrel sight to zero it). It works as advertised so far, and I love it very much. We shall see how it goes in the long run though. :) I have a feeling that this will work out VERY well though, and it does indeed seem sturdy, and very well built. For the sight issue (on my part), it is worth the money alone as long as it functions properly. ... show more

    • Best sight I've ever touched! Won't buy anything but holosun
Color: Black (Green) Reticle type: Multi-Reticle
Got this a few years ago in 2022. It's been on my daily driver since then. Been great. Only had to change the battery 2 times, maybe 3 times. Idk super great battery life. Regardless of the great stuff above, I don't know if they rate is as water proof or not but I went went fishing with a friend and our two boys. And the boys being boys decided to go for a swim. One started having issues the other tried to help and they both started drowning. I jumped in and grabbed them not even thinking about my boomstick. Did a quick shake and blow off of everything and even after getting it home and cleaning it well the sight still works just as good as before! Ive smacked it into solid things before and it's got dings in the frame but it's still sturdy solid! Won't be buying any other sight brands. ... show more

    • Excellent Dot - Good Value - Extremely Pleased
Color: Black (Red) Reticle type: Multi-Reticle
Excellent red dot. The frame is very solid. While I have no intention of putting it through a torture test, I do believe that it would hold up to even unreasonable handling. I love the side battery tray. That feature alone makes it a winner over other red dots in this size. Not having to remove the optic to replace the battery (and thus not having to re-zero) is a big win in my book. Several other red dots of this size require removal to replace the battery. Battery life is stated as 50,000 hours. I can’t speak to that, but my battery is several months old and still going strong. I like the 2 MOA dot. For the 32 MOA reticle I am still on the fence. But the nice thing is that you can just have the dot showing, just have the reticle, or have both. A push of a button just cycles through the three options. Plenty of settings to take it from dim to bright. For me, the brightest setting is too bright even in sunlight. Lowest setting is almost invisible, so you should definitely be able to find the right setting to fit your preferences. It also has night vision settings, but I can’t test those. This far outpaces the Romeo Zero it replaced. I bought a second one of these for my wife. She loves it too. I switched from a different red dot to the Holosun. She switched from irons to the Holosun. We both are extremely happy with it! ... show more

    • Great red dot
Color: Black (Green) Reticle type: Multi-Reticle
Why did you pick this product vs others?: Online reviews were generally positive. Reticle selector and brightness adjustments are easy to use. One drawback is that the buttons are on the left side and as a leftie I would find them easier to use if they were on the right side since I hold a pistol with my left hand. Ease of installation: Easy to install with the tool provided. Focus: The 32 MOA green reticle with a 2MOA center dot provides for more accurate shots at bc various distances. ... show more
