407K/507K Series 6 MOA or Multi-Reticle Dot Open Reflex Sight for Subcompact Pistols - Shake Awake Technology - Red/Green/Gold Options - Black/FDE

This little 507K was purchased to top off a new firearm that was pre cut to accept the 407K/507K. It fit like a glove and was simple to install. It performs flawlessly like all Holosun optics I've tried. The dot is easy to find and the multi reticle gives me 3 choices. This is daylight bright even in the brightest sun. Other Holosun optics I've had take a lickin and keep on runnin. I could by the BIG name super spendy stuff, but why. Holosun is miles ahead of the competition when it comes to design. For me every Holosun product I've owned has lasted. They're well built and priced well. Of course right after I bought this, I saw it on a great sale for $70 less. That's just my bad luck. Two big thumbs up Holosun and Amazon. Super fast shipping and our Amazon delivery people are the best of the best. Kind, cordial, and always professional. Happy Labor Day 24 to all. Stay healthy and safe friends. Be kind to each other, always

These are a must for those of us who wear glasses, increased my accuracy by 100%, 10 for 10 bullseyes on paper targets and the same for metal targets from 8 to 50 yards and beyond, expensive but worth every penny. High quality, great features, brightness adjustment is excellent, easy to mount, (use a torque wrench) and very simple to adjust with the help of a bore sight laser unit.

Perfect! Excellent quality and more importantly went right onto my sig 365x directly without a hitch. If you like green dots but also circle if desired, this is perfect for you

Good product. Good price.

Great sight for ccw. I have it on my 43X and it has been perfect. The reticle is crisp, the red dot is nice and bright, and the brightness levels are easy to adjust. Feels solid and reliable every time I carry. Really happy with this optic.

This was a great product that met my expectation.

Good optic with 3 different optic styles to choose from. 10 brightness settings with 2 that work with night vision. I installed this out of the box with my Sig P365XL. But only a 4 month battery life? That’s bad. They promise up to a year but I carry every single day and all day. I’m in a sunny state as well so my brightness has to be at a 7 or higher. I bought it mid February and it’s mid June and it already died. That’s pretty bad if you ask me. But it’s still a good optic. Just buy a 6 pack of batteries for the year.

The Holosun HE507K-GR X2 has been an absolute upgrade for my carry setup. The green dot is super clear, easy to pick up quickly, and works great in all lighting conditions—even bright sunlight. I love the shake-awake feature, and battery life is phenomenal. Fit and finish are top-notch, and installation was easy with the right adapter plate. It's tough, compact, and reliable—exactly what you want for everyday carry. Highly recommend it if you're serious about accuracy and quick target acquisition!

Love it, connected great.

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
