Features
- Features a 2 & 32 MOA reticle system with dot-only, circle-only, and dot-and-circle modes, allowing shooters to balance precision aiming and rapid target acquisition. Easily adapts to range practice, training drills, and fast-paced shooting scenarios where flexibility and quick alignment matter
- Parallax-Free Optics & Exceptional Clarity: The aspherical, multi-layer coated lens delivers a distortion-free, parallax-free sight picture through a large viewing window for fast and precise target acquisition. Advanced multi-layer coatings reduce glare and enhance optical clarity, while a hydrophobic lens coating repels water and dirtkeeping the lens clean so you can stay focused on the shot
- Read to Mount: Fits RMSc-cut slides out of the box and includes nine sets of anti-recoil mounting screws for secure and reliable installation across a wide range of firearms. To expand compatibility, MOS-to-RMSc and RMR-to-RMSc adapter plates are included, allowing the optic to fit even more handgun platforms
- Enclosed Emitter Design: Fully sealed, IP67-rated construction protects the emitter from impact, dust, and moisture, ensuring reliable performance in any condition
- Long-Life, Side-Loading Battery: The precision-engineered optical system minimizes power consumption, and paired with a high-capacity CR1632 battery, delivers up to 50,000 hours of runtime (mode 3) for long-lasting, reliable performance. The side-load battery design allows effortless replacement without removing the optic, maintaining zero on your firearm. An integrated battery-cap screw prevents loss during maintenance, ensuring secure and convenient operation
- Durable & Lightweight Construction: Built with a rugged 7075T6 aluminum housing, the optic resists debris, moisture, and impact, and is proven through livefire testing, 5,000G shock resistance, and drop tests. Weighing just 1.17 oz (sight only), the EM1 maintains a lowprofile footprint without adding unnecessary bulk to your pistol or mounting platform.

lol this is such a copy of the eps carry but I dig it. I have it 12oclock on my lpvo so not taking back shots as if it were on a pistol but it works and has held zero on a riffle. The window is large and dot visible. The only odd thing is that unlike most dots that immediately dim or increase this one kind of lags as if it’s on a dimmer switch. The brightness does adjust but you can see it gradually change. When I hold down the button to turn it off I see the brightness decrease to like 3-4 and then gradually disappear. I was trippin at first thinking I got a lemon. I now have a second one I’ll throw on my 43x and dump some mags to see if it’ll zero.

As long as this stays as a BUDGET option, this is a great value enclosed optic. Not having 'tested' it yet (durability or keeping zero yet), but just sighting it in and mounting it, so far very good. Machining, accessories (screw set, plates, battery) have been top notch. The enclosed optic seems decent, and the optic window is clear. Not the largest which is fine especially for a CCW/and RMSc footprint. It's meant for a compact/micro. Works and fits perfect on your Hellcat, P365, MC9s, Echelon, etc. Really good fit and finish. Hopefully the durability and ability to hold zero holds true. Will update once I go to the range. Have it mounted on a 10mm compact and this will test how 'durable' and 'can it hold' we'll find out. The dials to adjust the windage and elevation is easy. The mounting with included plates (plastic) was easy. Screw set is comprehensive and EXCELLENT. Thank you!

Decided to give this thing a try after seeing a lot of positive reviews and content. Upon getting to the range and "sighting it in" I noticed the location of the dot had totally changed from where I set it to. I inspected the em1 and also could see the dot changing position just by tapping the casing of the red dot. I immediately took it off my pistol and initiated a return right at the range. I would not trust any zerohawk devices to protect you or the lives of anyone you love.

Mounted on an APX A1 Compact. Easy to zero and has a clear reticle. Great value, thus far it seems just as good as other much more expensive similar RDS’s. Many reviews online including torture tests which shows durability. Expect the same. Great customer service as I also got the green 6MOA version. That version did not work with my astigmatism. Anything 4moa and above as I discovered. Zerohawk sent a prepaid label to return and sent me a 2/32 replacement. Direct mounted to CDS9 and will zero soon.

The Zerohawk EM1 looks to be a quality optical sight, on par with its nearest competition. It directly mounts to a RMR cut, making it an ideal sight for my Ruger RXM allowing it to co-whittnes with its iron sights. I haven't been to the range yet to ultimately sight in my pistol, but I don't forsee any problems. The dot moves properly when the elevation and windage screws are turned and the detents are tactile.
