Rugged, reliable, and smart.
This Holosun optic stands out as an exceptional piece of engineering, making it a premier choice for an everyday carry (EDC) setup. It offers a sophisticated blend of high-end performance and rugged reliability while remaining at an accessible price point. Out-of-the-Box Precision and Setup The optic arrives essentially zeroed right out of the box. Included in the package is a dedicated tool for fine-tuning windage and elevation, offering crisp, tactile clicks that adjust straightforward. While the initial alignment is impressive, using a laser bore sighter is a great way to perfectly dial the dot to the specific ballistics of a firearm for absolute precision. Advanced Motion-Sensing Technology The motion-sensing technology is highly effective. The "Shake Awake" feature ensures that the moment the gear is handled, the Optic instantly activates the last used brightness setting. To conserve power, it is programmed to shut off automatically after periods of inactivity, extending the battery life. Installation and Fit Depending on the specific slide cut, a separate mounting plate may be necessary. While these typically cost upwards of $50, the investment ensures a solid, secure, and precise fit that remains stable under recoil. Once properly mounted, the housing sits low enough to provide an excellent lower 1/3 co-witness with standard iron sights. But better if the firearm has optic iron sights. Side-Loading Battery Compartment This design is a significant advantage. Unlike optics that require removal from the slide to swap batteries, this side-loading feature allows for battery changes without losing the zero or needing re-adjustment. Reticle Clarity The green dot is incredibly crisp and bright, making it very easy for the eye to acquire quickly in various lighting conditions. Construction The build quality is top-tier, feeling robust enough for the rigors of daily carry without adding unnecessary bulk. Final Assessment I prioritize quality and reliability; this optic represents an excellent investment. It delivers its promises of durability and precision, serving as a dependable "set it and forget it" solution for a defensive setup.

Awesome and easy to install
Actually, I have the green dot. I love the shake-awake which means I can leave it turned on. When the battery finally does go, I like that the battery can be replaced without removing the unit. It was much easier to center than my old sight. It even comes with a tool to install and adjust.

GREAT but with caveats
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.

10/10 . Wish it came with the right screws
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.

best micro optic
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.

赤ドットよりグリーンの方が視認性良いと思います。レイバンのサングラスと同じようにグリーンは対象の輪郭を見易くしてくれると思います。屋内でGBB で利用ですけどね。

この機種以外のホロサンを3個使っていて極小が欲しく この機種にしましたが、やっぱりホロサン見やすくて良いです。この小ささでサークル ドット サークルドットと3種類表示出来るし何よりクリアな視界が最高です。他メーカーのレッド表示より格段クリアです。 購入2週間でもう一個購入しました セカンドウエポンをこれに2丁共変えました
