Features
- 6 MOA Dot:A 6-MOA dot fosters quicker target acquisition and better visibility, making it ideal in high-stress situations. A larger dot adds consistency to presentation and target alignment.
- Side-Loading Battery:Effortless battery replacement without removing the optic ensures hassle-free re-zeroing. A premium-grade battery features easy accessibility while maintaining steady performance.
- RMSc Footprint:Designed for RMSc Footprint-cut, optics-ready slides. Non-RMSc slides require an adapter plate (not included). Please verify compatibility before purchase.
- Motion Sensor Function:A motion sensor activates the optic at the slightest motion, and powers down after 3 minutes of inactivity to conserve battery.
- Low Power Indication:If battery voltage drops below 2.2V, the reticle will quickly triple-flash once per minute to recommend an imminent battery replacement.

Have this mounted on a Canik MC9 prime, and it is a perfect and snug fit with the included screws. The buttons can be a little hard to press if you're wearing gloves, but otherwise they function quite well and have a nice tactile "bump" when you depress them. The glass is clear and easy to clean. The laser itself handles all light levels with ease; it gets brighter than the sun at max level, making it perfect for daytime training, while it offers multiple night-modes that I've found very useful in a variety of circumstances and training conditions. Additionally, the added circle and circle-dot reticles you can cycle to are clear and crisp, and I've had a lot of success with the circle dot (though I swear the dot itself sits a little below what should be the center...others say I'm crazy but idk) at longer ranges. It has survived 3 accidental drops on concrete and 3k rounds with no issues other than needing to reapply loktite a few days after first mounting it. I have not noticed any significant zero drift after reapplying the locktite and re-zeroing the pistol - thousands of rounds of various types with no issue. Battery life is outstanding so far, though they make it even easier to swap the battery out so no worries there. For the price, this should jump to the top of the list for anyone looking for an RMSc pattern pistol optic. A homerun for OSIght!

Another good product by osight. Absolute cowitness and direct mount to S&W shield X. Nice smooth finishing all over, clear and crisp dot. Easy controls. Mounting hardware provided and accurate to application. It is a little bit wider than some of the competition due to it thicker frame all around. Very well priced for what you get.

Very pleased so far. Good build quality at a very competitive price. Prefer the large 6 MOA dot to smaller dots, much easier to pick up and and see. Shake-awake (motion-sensing) works well and should significantly extend the battery life. Easy to mount (make sure to use blue threadlocker on the mounting screws). Easy to adjust for elevation and windage. Side-mounted battery is a big plus. Some designs use a bottom-mounted battery, requiring removal, battery replacement, re-installation and re-zeroing just to change the battery.

Great red dot. Clear and big window. Better then Holosun and cheaper. I will buy more of them

Had this for about 3 months on a Canik TP9 Elite SC. Installation was super easy. Have about 400 rounds through it and shot a Practical Pistol course. All Alphas except for 3 Charlies and 1 Delta. Accuracy is great and has held zero. Seems pretty durable, but I won't be on any battlefields anytime soon, so I'm sure it will handle what I plan to put it through. Co-witness with the Canik is great and 6 MOA is great for fast dot acquisition.

Unboxing video and first impressions. The build quality seems very solid and has a nice clean sleek look to it. Packaging of the product by the manufacturer is 10/10 awesome. The item functions fantastic and seems like it will stand the test of time. Shake awake feature works great and 6MOA dot is a great size. Side load battery compartment is the only way to go! It was super easy to install with the RMSC footprint. It fit directly and very snug onto my hellcat (had to tap it on with rubber mallet). The only reason or 4 stars instead of 5 is that I have not been able to test it extensively with many many rounds and recoil. That and the fact that this is a relatively new item with a very short track record compared to some others, is why I gave it 4 stars. If this item measures up (the way I think it will), we will have a new competitor among the mid level red dots on the market. If OSIGHT backs up their products and keeps them at this affordable price point, they COULD end up taking over the market!

I was buying Cylee for my lower guns (Trijicon is on all my premier stuff, sorry but it’s the best and mosh durable) For the money, this Osight is incredible. Easy to use, align, and adjust. Fabulous value and crystal clear site picture. Highly recommend for your pistols under $1000.

For the price, you cannot beat Osight. I like the open emitters because they are typically low profile and aren’t big and bulky. I have the Osight K mounted on my Walther PDP and it’s great. Nice bright red dot, still zeroed after about 1,000 rounds, and it sits low enough to co-witness my front iron sight. Expensive red dot optics don’t always work as well as you’d think. Osight has a great product and business model. I’m hopefully they continue making quality optics for affordable prices.
