Holosun’s HE507K X2 Open Reflex Sight was designed for use with handguns and works particularly well with concealed carry pistols. This micro red dot is equipped with the MRS Circle Dot reticle, which features a precise 2 MOA dot in the middle of a 32 MOA ring and has 12 brightens settings, two of which are night vision compatible. The HE507K X2 utilizes Shake Away technology to provide instant activation at the slightest movement, and shuts off during periods of motionlessness. To better accommodate concealed carry applications, the HE507K X2 is outfitted with Lock Mode, which locks the buttons to prevent accidental changes to settings, and positions the buttons lower to keep them out of the way.

Great little sight I use a red on my cz shadow and this green on my cz p01 omega I really like the foot print of these k sights on cz slides very little overhang on the sides with the narrow cz slides battery life seems good on my red been on for over a year I know green is supposed to be more battery hungry we will see

I have many Holosun Optics. They work every time. You can certainly spend more but you won't get more.

Great green dot for a P365X. So easy to use. I love the lockout feature because I grab the rear of my slide to cycle it, and hit the +- buttons too often. Lockout prevents me from sabotaging myself by dimming my sight every time I load a new mag. Great product.

My “Agency” has been putting the red version on Glock 43X MOS pistols for people in “soft” assignments. I went with the green model for my 43X MOS. Probably due to my older eyes, the Circle-Dot reticle gets a bit fuzzy, so I switched it to the Dot reticle. Zero’d at 10y. It’s holding zero and is fast/intuitive while shooting. Only complaint we’ve had is short battery life. Overall, great optic for it’s mission.

I love the circle without dot. Thought circle with dot to busy and did not care for just the dot by itself. Easy to install, easy to sight in, and the size is perfect. So why three stars? For starters, once installed, I tried to turn it on for the 1st time. It wouldn't turn on. Had to purchase a new battery at Wal-Mart. A bad battery wouldn't cause 3-star rating. Why I gave a 3-star rating is because the shake-awake function didn't work. It would go to sleep after 10 minutes shooting. Attempts to hold + down for 10 seconds to change time off function would lock up controls and leave it on permanently until battery was removed. Holosun was quick to provide a pre-paid RMA shipping label. Hopefully turn around at the factory will be fast.

This optic fits perfectly on my H&K VP 9 and H&K VP 9 SK. I used the #8 optics plate mount from HK Parts.

To date, I have had better luck with Holosun than any other optic. I see no reason to expect anything different out of this little guy. Mounted well, great circle-dot reticle, I find the green reticle easier to pick up than red, though I do not feel too strongly about green v/s red thing. Zeroing was smooth and quick. I believe I am, and shall be, a happy customer. As for EuroOptic, these guys are professional and friendly. Shipping was quick. I am always happy to business with these folks.

So far I love it. Haven't had it long but it replaced a Romeo brand sight. I love the green large circle with small dot. Quick target acquisition with the large circle. Good adjustments, easy to replace battery, the unit seems solid, and was easy get the gun sighted in. I recently purchased a second one to install on another gun, and plan to buy a 3rd.
