HOLOSUN SCS MOS Green Multi-Reticle 2 MOA Dot & 32 MOA Circle Parallax-Free Reflex Pistol Sight Compatible with Glock MOS Full-Size Handguns - Solar Charging Sight (NOT for Glock 43X MOS or 48 MOS)

⭐️⭐️⭐️⭐️⭐️ 5/5 — Holosun SCS-MOS on my G45 I recently picked up the Holosun SCS-MOS for my Glock 45, and it has instantly become one of my favorite upgrades. The direct-mount fit is perfect—no plates, no extra height, just a clean, factory-level look that keeps my sight picture natural. The green reticle is incredibly crisp, even under bright range lighting. Whether I’m running the 2 MOA dot or the circle-dot, target transitions feel fast and effortless. The auto-adjust brightness has been surprisingly reliable, and the internal rechargeable system means I never have to worry about swapping batteries. Performance-wise, it’s been rock-solid. Zero held perfectly through multiple sessions, recoil cycles, and holster draws. On the G45, this optic feels perfectly balanced and purpose-built. If you want an optic that’s rugged, low-profile, and insanely clear, the SCS-MOS absolutely delivers. It took my G45 to the next level. Highly recommend.

Perfect fit on my GLOCK 20 V 10mm Full Size 15 Round.

This is a great optic. Much sharper dot and "easier to find" than some of their competitors. Very easy to install. Trivial to "zero." After 500 rounds, it is holding zero and functioning perfectly. One downside (that I can live with) is the screws. Holsun is "cheap" compared to their competitors. They give you just the 2 required screws. If you mess one up or lose it, you're ... well, screwed. ~ $10 bucks to get another pair (This happened to me on an older Holsun 507C where I had to cut one of the screws that impinged on the extractor push rod...I cut the screw too short and spent over a month trying to a replacement. A second complaint is the fact that the screws they do provide come with a big "glob" of Loc-tight. These tiny, tiny screws with very fine threads are hard to start and you have to be very careful to not cross-thread them. The glob of pre-cured Loc-tight keeps you from feeling what you need to feel to be sure the screw is not cross threaded. It's hard to tell if the resistance to turning is from the Loc-tight or from cross threading. I much prefer clean screws that I can insert to test then apply LIQUID Loc-tight that lets you "feel the threads." Waiting 24 to 48 hours for the "fresh" Loc-tight to cure is a small penalty to pay for being sure you didn't "screw things up." (i.e. cross thread) Overall, a great value and I'll probably buy another one. I'd recommend it to my friends

Great sight and fit MOS cut slides without and issue. Very bright and crisp even with a small astigmatism. The solar charger is great.

I don't know how else to describe this than it's 5 star rating. On an MOS47, with a Radian comp, it shoots like a dream. It holds it's zero, the serrated groves fit the frame perfectly, and doesn't hang over the slide, it's a perfect fit. The sight also sits low enough for for standard size iron sights to be used without any difficulty. Its weird having a pure solar power charger with no other way to change the battery, how to check it's charge, or a secondary or backup charging ability. It does have a function to let you know when your battery is low, but I've not seen it activate as I keep it on a low light mode. Its supposed to be a feature of turn on and forget, but I wonder how it's supposed to charge in a holster with a hood and retention. Any future MOS Glocks I get will have this sight installed, and previous red dots are getting taken off for favor of this.

This was the outstanding solution to the steamy bag of duece that is Glock's MOS plate system. After having been domed center-forehead by a 507c 3 times for it detaching itself from the plate under recoil, i opted to make a change. For the record, it does not matter what type of threadlock you use on a heavy recoiling round. The 2-3 threads that contact the MOS adapter are insufficient to secure with 10mm/45/357 SIG recoil. This unit thread right in as advertised, co-witnesses, and the shake awake thing solves a whole bag of non-MOS issues i have with red dots in general. 10 out of 10, would buy

I have several Holosun optics, open emitters like 407C, 507C, 407K, 507K and closed emitters like EPS and EPS Carry and 403G. Have not had any issues with any of them and I use them regularly in training and in handgun/PCC competition. Recently I got a Glock G47 MOS and was considering putting a 407/507 or maybe EPS series optic on the slide. Used the factory MOS plate to borrow a 507C from another pistol. But the fit on the slide was oversized and the MOS plate was flimsy, easily bent sheet metal. Was happy with general function on the G47 but wanted something smaller footprint, no iron sight obstruction. I trust Aaron Cowan's Sage Dynamics optics tests -- have bought & used many optics based on his positive reviews, and found his review valid in all respects. He gave the Glock MOS version of this new Holosun SCS a good rating. So I gave it a try. Fits very well on the MOS slide cut. Factory iron sight picture unobstructed. Green reticle is plenty bright. Brighter than I'd prefer, but that really just makes it more like a 5-6 MOA dot, and I already like the EPS with 6 MOA dot so it's fine. And it does a nice job of adjusting to ambient light, better than the 407/507 series do, in my experience. I don't use auto-adjust on the others. As to green vs red, I have a selection among my optics and don't find any difficulty using either, except in very narrow cases of certain color backgrounds, green can wash out a bit easier. For a good sense of green vs red reticle choices and where they wash out, look on youtube for a video by deltathirtyfour, about reticle choices in ACOG optics. He has excellent video footage of backgrounds where green reticles can wash out, and where red ones do as well (also gold/amber in his comparisons). I give the SCS MOS a 5/5 in all categories. Be sure to read the manual to learn where the well-camouflaged power button is on the optic. I didn't even see it myself at first.

Very nice red dot and the fact that it mounts directly to my Gen 5 G34 MOS without using the adapter plates is very desirable. It mounts lower and more firmly than using a plate and the stock sights are usable through the red dot window too - so no high snaggy suppressor height sights needed. Whoever decided to make these with the ability to mount to specific factory cut for optics pistols is a genius. The battery system with the solar recharge means no worrying about the battery. A great replacement for the Vortex Razor it replaced. I like the reticle choices too, the circle really aids in picking up the dot faster and it is closer to the barrel axis. Win.

購入後数日で電池残量が少ない警告が出たので経過を見て1ヶ月経つ前に相談。商品を送り試験してもらった結果、何かしらの不良があるということになり新品交換してもらいました 交換されてきたものは以前とは見た目からして別物級に出来が良く、最初に届いた時にガッカリしたピンクのレンズや接着剤ボコボコの無い個体が届いたので、大変良かったです。 何かおかしいと思ったら早めに相談したほうがいいです。それなりに高い買い物ですので。
