What is the HOLOSUN - HS407K-X2 6 MOA Red Dot Reflex Optical Sight Black?
HS407K-X2 REFLEX OPTICAL SIGHT

The HS407K X2 is an open reflex optical sight designed for subcompact pistol applications. The HS407K X2 improves on the previous version by adding Lock Mode which was first introduced in our 2018 LEM pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes.

Additional features include Holosun’s Red Super LED with up to 50k hour battery life, a crisp 6MOA dot, and Shake Awake. The durable housing is made from 7075 Aluminum, uses Holosun’s K footprint, and houses the 1632 battery in a side-mounted tray for easy replacement when needed. The HS407K X2 is a direct for P365X/XL and requires an adapter plate for slides with a four-boss interface.


FEATURES:

Shake Awake™
Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optic’s LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use. This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed.

Multilayer Reflective Glass
Holosun’s use of Grade 5 Titanium in certain Elite category optics and laser devices results in unparalleled strength and durability. Holosun Grade 5 Titanium has more than double the tensile strength and has five-times the fatigue strength of 7075 Aluminum. Grade 5 Titanium is also able to withstand the corrosiveness of seawater making Holosun Titanium model optics and lasers suitable for use in maritime environments.

Dove tail mount
Looking for a mount for a mp 40 shield also amount for a Glock 26 nine and the amount for a 380 shield dovetail

Great Sight
I have a Holosun Greendot sight and it really made sighting my rifle much quicker and easier, I will put one on my pistols just as soon as I can. Thanks

RUGER MAX-9
The Holsun 407 is very nice worth ever penny. When considering an optic for my Ruger Max 9 I wanting something of quality but that doesn't break the bank. Important information: When installing on the Ruger Max-9 you will need to trim the screws down, as they are to long. It seems that Ruger does not tap the holes to the very bottom of the slide, therefore shorting of the two screws is required.

407k
Dot seems much larger than 6 moa. Compared to other red dots with 3-4 moa dots not a very refined circle. Might be my eyes. Maybe the quality of the glass was the emitter. Would still be sufficient for self defense distances, but not the best. For the price and robustness of the optic still a good ccw choice. But I prefer the over slightly smaller, lighter shield rmsc. Better, clearer glass. Crisper red dot. Seems durable enough for my needs

NOT RMR compatible
Got this to put on a Brownells RMR cut slide before realized they are not compatible as is. Of course the description or detail of this product make no mention that it uses an entirely different standard. Now I'm going to have to buy an adapter which puts the total cost to run this low end optic close to an actual RMR. Talk about insult to injury. Aside from the annoyance of now having to pay ~80 bucks for an adapter plate, its also gong to increase the profile of the sight, which defeats the whole purpose of buying the smaller 407K. Admitedly, partially my fault for not researching more before, but I stand by the point that it should be more clearly spelled out in the Item Description or Specs if it uses something different from the RMR cut, which was half the selling point of HoloSun products, that they fit the more popular mounting template...
