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.

Got this for my 43x and works perfectly. Had to get an adapter plate but that was expected. It mounts study and comes with multiple differ length screws depending on what you need. It is very durable and have not had an issue with it so far. The red dot is clean and is easy to find. The brightness is also adjustable.

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.

The reviews speak for themselves. The 407/507 series has become known as one of the best in pistol red dots. I started out with a Shield RMSc for a G43x. The RMSc's auto brightness feature is a detriment in mixed lighting, as is the need to unmount it to change battery. The one thing I liked about that optic was the dot size. 4MOA is a really nice goldilocks zone between the 2 or 3 MOA dots and the 6MOA dot on this 407K. The 6MOA dot is really crisp with clean edges. I wondered if I had an astigmatism as long as I've been shooting, and it was this dot that taught me the others have all just been slightly fuzzy dots. This one is a nice round circle. For a pistol it's a very functional size but 4MOA would be just as quick to pick up and a little better for precision. 2MOA is too small and the 32MOA circle in the 507K was TERRIBLE in my opinion. I tried the 507K before returning it and finalizing on the 407K. The EPS Carry wasn't available when I bought this and I do think the enclosed emitter would be superior. I get some lint on the inside of the window and could see debris getting in the emitter. The only other thing I'd like to see is the front lug holes to fit the RMSc mounting pattern without a plate. I bought the C&H mounting plate for this which works great. I considered shaving down the lugs to direct-mount the 407K but decided I could manage with the plate. If you do file down the lugs at a G43x/48, this can be flush mounted. If it's flush mounted the stock sights are visible at the bottom of the window. With a plate the bottom half of the front sight dot is cut off, so higher sights would be needed. With 1,000 rounds down range with this I trust it as a carry solution. I might upgrade to an EPS Carry at some point for the enclosed emitter, and would welcome a 4MOA option if Holosun releases one later.
