HOLOSUN HS407K-X2 Classic Reflex Red Dot Only Sight

Where to begin? Whenever you buy budget, or less expensive optics you always have to be skeptical if you're a smart buyer. If you're serious about quality, you really don't have to go any further than Holosun. I will admit, that this is the first time I ever bought a HOLOSUN product, and I have pretty much stuck to higher end, or if I was going to buy budget I looked at o l i g h t. For example, this has a shake awake or even better than that, I would call it a motion sensor. I think that's what they call it as well. What I mean is, as soon as you pick it up, the optic turns on and is ready to rock abd roll. It also turns on in the last setting that you had tuned in. This includes brightness, zeroing and clarity. After 10 minutes of non-use, the optic automatically turns off. I can't imagine anyone not liking that, but they do allow you to lengthen that time to 30 minutes and on to over an hour and a half and then even turn the feature off, although I don't have any idea why anybody would ever do that. To be perfectly honest, I was skeptical at first. I am a believer now. Let me address one elephant in the room. This optic does not come with any kind of a mounting plate those are firearms specific and you will have to purchase it separately they run between 30 and $50. They are titanium, in my case I needed to mount it to a Hellcat, and the plate was perfect! This is no slight on the manufacturer because they would have to include many, many different types of plates to mount different Optics across many platforms. It is irritating to have to buy a separate mounting plate but I completely understand why. Now there's another manufacturer out there that claims that you don't need a mounting plate for theirs however I've learned a lesson from this particular manufacturer in fact I actually have an email from that manufacturer with their similar product that's like $100 less however, there are some issues with regard to the perfect fit and he told me that I should use a tach hammer to hammer the site into place this is not this manufacturer but the manufacturer who I referred to earlier in this review. So this super bright Marvel doesn't need any of that you'll never have to whack this with a hammer or anything else. Kudos to the manufacturer however they gained the technology, (I know that this troubles some folks myselfincludedin some instances), however, they have improved on the technology, not merely mimicked the technology. In my humble opinion, this is probably worth about twice what it's listed for. It has an awesome build quality there's no question about it, the brightness we'll go as bright as you could possibly ever need and you can dim it in the same way depending on your environment. I can go on and on but I won't thank you very much this is an awesome purchase if I could give this 10 Stars I would!

Fast shipping. Even with an astigmatism I’m able to get a pretty clear dot, still somewhat blurry but a lower brightness setting helped alot! Easy mounting!

I recently added the HOLOSUN HS407K X2 Red Dot Sight to my subcompact pistol, and I’m thoroughly impressed with its performance. This sight is an excellent choice for anyone looking to enhance their shooting experience, particularly with compact firearms. First, the build quality is top-notch. The HS407K X2 is lightweight and sturdy, designed specifically for subcompact pistols. The compact size doesn’t add much bulk to the firearm, which is perfect for those who value portability and ease of use. The 6 MOA red dot is bright, clear, and highly visible in a variety of lighting conditions. Whether I'm shooting outdoors in bright sunlight or indoors with low light, the dot remains crisp and easy to acquire, making target acquisition faster and more accurate. The brightness adjustment feature is also excellent, allowing for quick changes to suit your environment. I also appreciate the shake awake feature, which conserves battery life while ensuring the sight is always ready when you need it. The battery life is impressive—I've been using it for weeks without needing to replace the battery, even with frequent use. Another great feature is the robust construction, with the X2 offering superior durability. The sight is shockproof and waterproof, which gives me peace of mind when using it in harsh conditions. Overall, the HOLOSUN HS407K X2 is a fantastic red dot sight for subcompact pistols. It provides fast target acquisition, excellent battery life, and impressive durability—all in a compact package. If you're looking to upgrade your firearm with a reliable, high-quality sight, this is definitely worth considering.

These things should not cost so much...but this one does do very well on my Rock 57 from Palmetto. Mounts without adapters on my sidearm.

Bought the 407K-X2 6MOA red dot for my GF's S&W Equalizer and it fits perfectly, no adapter required, but I did have to buy different mounting screws than the ones supplied. I guess the shake awake is working because the dot is on every time I pick it up and look. Have not actually left it in a position where I can see the dot to make sure it shuts off after a time, but I've not had to replace the battery yet and it's been 2.5 years as of this review. The dot is plenty big enough to easily find and see and at the typical ranges you would expect to use a pistol, it doesn't cover so much of the target that you cant see the target. I do wish it had the adaptive brightness, but then it probably wouldn't fit as well as it does.
