HOLOSUN HS407K X2 Red 6 MOA Dot Open Reflex Optical Sight for Subcompact Pistols - Durable Parallax Free Unlimited Eye Relief Handgun Sight with Aluminum Housing & Shake Awake Technology

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!

Holosun 407K X2. Before I 'review', it should be said that this is my first red dot on a handgun, and I fell in love with the concept, sooo... Mounted it on a new Equalizer, here's my info and thoughts; 1) Yes, it fits perfectly on the Equalizer with no plate or mill work needed on the slide. 2) No, it DOES NOT come with the correct screws to mount the site. This is bogus on the part of Holosun and needs to be addressed. Too pricey of a sight to not come with all types of mounting screws. 3) Because of that, you will need two 6-32 black oxide flat head socket screws. You can get these at most local hardware stores for about .40 cents each. I bought the 1/2" long overall length screws because that's all they had, but 9/16 or even 5/8" length would be better. The 1/2" do work though. Make sure you clean the oil off the screws and out of the slide holes before putting the loctite on and putting the screws in though. 4) Yes, it will barely co-witness with the OEM iron sights. It's not perfect by any stretch, as you can only see about 20% of the front sight, but in an emergency situation, the iron sights would be usable and accurate with the 407K mounted. 5) It works/fits very nicely with the IWB holster I bought (crossbreed). Took it to the range today. Wow. I was impressed! The 6MOA is perfect for me, and it only needed a few clicks up and right to be dead on after mounting it. Once sighted in, it held zero flawlessly round after round. I really like that you can change the battery without removing the sight, and the shake awake feature is super-sensitive and works very well. I love being able to stay on target with both eyes open to the surroundings. Despite the missing screws debacle, I would still buy it again. Nice sight.

Nice red dot and price was good

Good quality product. Fits perfect on my Sig Sauer p365x.

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.
