    • GREAT but with caveats
Color: 6 MOA (Green Dot) Style: Black
Review Image by Clean Capture Clean Capture
The media could not be loaded. This is my 3rd Holosun purchase and I couldn’t be happier. This one I got specifically for my EDC. It’s a reflex which means it is not enclosed and sealed off to dust, rain and debris, but it’s still super reliable. The battery life is insane, boasting around 50,000 hours - that’s like 4-5 years. So if you have the dot at a moderate brightness, and the “shake awake” setting on, which puts the dot to sleep after 10 minutes and instantly turns on at the sign of any movement whatsoever, you can change the battery once per year or once every two years and still be confident it’ll be at the ready when you need it. This was essentially zeroed out the box for my p365 but it does come with a tool to adjust windage etc if need be, simple clicks. I recommend a laser bore sighter in red to properly align the dot if you need one. Other than that it should hold zero easily because of the side panel battery compartment, which means you can change the battery without having to remove the Holosun. This thing is durable, has a great bright and accurate laser with a low co-witness depending on your irons, it’s easy to use with simple controls, and it’s durable as heck! The only small caveats that would make me want another model would be: 1. If I wanted enclosed 2. A different Holosun with the solar backup panel (this does not have it but it’s a VERY slim and small reflex) 3. Variation of the dot (this is 6moa green dot only, no crosshairs or circles) Well built, affordable and high quality. You can’t go wrong. ... show more

    • Awesome sight, but....
Color: 6 MOA (Red Dot) Style: Black
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. ... show more

Very well made. Holds zero and has a compact footprint. Outstanding piece of equipment and it’s a better price point than other brands. Get it.

    • best micro optic
Color: Multi-Reticle (Red Dot) Style: Black
I beat the hell out of this thing and it still runs. never had a problem with seeing the dot in the summer sun. Battery life is so good im not even sure if I've replaced the battery in years, I should probably do that right now come to think of it.

    • 10/10 . Wish it came with the right screws
Color: 6 MOA (Green Dot) Style: Black
The optic itself 10/10. I fw the fact that the dot can only be seen by you. They will never see it coming. It was a quick install. The only thing is the screws, The screws that fit were too long . I had to use some other ones. If u buy this product you'll need shorter screws. They sent me like 3 sizes 2 were too fat and the other was too long. This is something they should fix especially with it being almost $300. ... show more

    • Amazing quality and fit.
Color: 6 MOA (Red Dot) Style: Black
Amazing quality and form factor. Mounted on a Taurus PT111 G2. I recommend picking up a mounting plate from Galloway Precision. I tried two mounting plates from Amazon and neither were worth the money and time.
