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)

Perfect for MOS cut pistols. Run on my 19.5. Have been very rough with it & stays zeroed. Reliable & durable for edc. Don’t need adapter plate so fits flush with slide and cowitnesses with stock irons.

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

Super quality and perfect fit.

Everything it promised. Easy to clearly co-witness. Green dot is always easy to see day and night and easy to adjust. On/off is not easy to manipulate but that is no bad thing. It is solar rechargeable with a long battery life so no need for it to ever be off. Has held zero on my G47 after more than 500 rounds.

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

⭐️⭐️⭐️⭐️⭐️ 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.

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.

awesome sight. my first pistol dot. well worth the money. looks like it should've came from the factory this way. goes great on glock 19 gen 5

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。
