New From Shield Sights: RMS-C Red Dot for Sub-Compacts

Shield RMSc

Back in June I reviewed Shield’s RMS, or Reflex Mini Sight. I think it’s one of the best (if not the best) red dots on the market for pistol use. It’s a perfect fit for my G19 MOS and is narrower than most, but would still hang off the sides of a G43, Shield, or other single-stack, sub-compact pistol.

With the growing popularity of equipping pistols with optics — even sub-compact CCW guns — Shield has released an even skinnier version of the RMS, called the RMS-C (compact). It’s designed to fit these diminutive guns without increasing the width of the slide. Shield Sights‘ press release follows . . .


For Immediate Release – Dorset, England, U.K. – Shield Sights is pleased to announce the release and full production of the RMS-C.  The RMS-C is a compact variation of the RMS that has been specifically designed to be a perfect fit on sub-compact or slim frame pistols.

The RMS-C is an answer to the rising demand for red dot sights on compact EDC pistols.  Until now there has never been a red dot sight that maintains full functionality in a slim and aesthetically pleasing package for sub-compact pistols like the Glock 43 and Smith & Wesson Shield.  

“After years of declaring that we make the smallest sights we noticed a space that was not being serviced by anyone. Brought to our attention because the customer base was now happy to mount the RMS on to sub compact pistols and accept the sight overhanging the slide, this was not acceptable to Shield so we set the task of miniaturising our RMS to fit the century old 1911/2011 slides, Glock 43’s, Smith & Wesson Shield’s and other single stack pistol slides”

The RMS-C has the same bolt pattern as the original SMS/RMS so users with slides already cut for the RMS can easily swap sights if they choose to.


– The RMS-C is machined from strong aerospace grade aluminium.
– Very fast automatic brightness adjustment
– No overhang on G43 or S&W Shield
– Very low profile to Co-Witness standard iron sights
– 2-3 year average battery life with standard CR2032 battery
– Weight: 17 grams / .60 ounces battery included

The RMS-C is available with the option of 4 MOA or 8 MOA dots with an MSRP of $430.

About Shield

SHIELD was formed in the early 1980’s in Great Britain. Shield continues to manufacture the world’s smallest, lightest, toughest mini red dot sight. Sold under other brand names for many years, you may know the Shield Mini Sight as the Firepoint, Tasco Optima, Trijicon RedDot or JPoint. Based on our in-depth knowledge, accumulated through 30 years in the industry, we are continually seeking to develop innovative products that will enable you to hit the target early.

    Jeremy, how is yours holding up?

    1. avatar Jeremy S. says:

      Bueno. My JPoint’s lens is now scuffed from using it a lot — EDC’ing it for multiple years, and just generally not taking very good care of it (e.g. it goes in the range bag with other stuff and usually isn’t protected with a lens cover) — but it isn’t noticeable when you’re actually shooting with it. Only if you’re focusing on the lens instead of shooting normally. I haven’t had the RMS long enough to comment on its long-term durability but so far it’s 100% as-new. I’ll go ahead and expect the lens to wear the same way over time, though it’s possible that, since it’s like 4 years newer, the anti-scratch coating is even better. I do like the aluminum frame of the RMS better than the polymer frame of the JPoint. I change my JPoint’s battery every year now even though I don’t have to…it went a lot longer on its first battery and was still just fine when I swapped it out.

      I like these units. I think their only shortcoming is that they aren’t submersible or rated for use in extreme wet conditions. I do believe Shield is going to be releasing a solution for that, but for my use I never much cared. I’ve used mine in the rain and it was fine.

      1. avatar Rusty Chains says:

        Thanks! These seem small enough for concealed carry, and my eyesight isn’t what it use to be, so regular irons are tougher for me to pick up than they use to be.

    This is the wave of the future. Someday this will be stadard equipment on a carry gun.

    1. avatar Jonathan-Houston says:

      Seriously? Who has time to look down a barrel, let alone through a red dot, in a defensive gun use? It’s point and shoot. Simple as that.

      All this does is add another distraction and bulk up your carry piece, giving it that many more angles and edges to get snagged on.

      1. avatar tsbhoa.p.jr says:

        stadard must be a new word for you.

      2. avatar TexTed says:


        Not every DGU is an old-west-style quickdraw event. Almost every DGU you read about in the National Rifleman magazine is a slow event — slow enough that most folks have time to go and get their gun from wherever it is. And just about every DGU that doesn’t end in firing is a slow-enough event that a red dot would not hurt and would probably help.

        The bulk comment I agree with. Those things have got to get flat and flip up before I’ll consider one, as I pocket carry 95% of the time. But if they do — and they’re proven reliable — I’ll be all over something like that.

        J-H, for those quick self-defense cases where you’re shooting inside of 5 yards (out to 7-ish if you have a consistent presentation), you don’t bother with the dot. The entire frame of the optic becomes a giant ghost ring sight. If it’s in the ring, it’s getting hit. If you even go to that level. Like you said, contact range stuff is often point shooting and there’s no reason to think a dot prevents you from doing that. If you can ignore your iron sights I assure you you can ignore a dot.

        Despite practicing with an optic on my pistol, I’m not faster with it vs. iron sights inside of about 15 yards. It’s about a wash, or possibly a bit slower with the optic if I’m trying for A-zone hits vs. self-defense just-keep-it-on-the-torso shots. At least on that first shot. Subsequent shots it’s about a wash with any nod going towards the dot. Beyond 15 yards, though, I’m faster and more accurate with the dot. I’d take and hit a head shot at 50 yards with the dot. I’ll hit a silhouette torso all day long with the dot at 100 yards. It may be a wash at close range, but it’s a HUGE benefit at long range. Even at 25 yards, my confidence with the dot is way higher than with iron sights. I switched to it when I also switched (on most days) to carrying a compact, double-stack gun instead of a sub-compact, single-stack gun as my EDC. Which was in somewhat of a response to random acts of terror and viewing that as a potential threat, whereas before my envisioned potential threat was a close-up, personal attack on me or someone I’m with. In adding the public shooting sort of scenario to the “reasons I carry a gun” list, I made that decision to increase round capacity and increase my ability to make precision hits at longer ranges.

          Shooting someone at ranges of 25 yrs or more are likely to have you defending yourself on a murder charge or at least a civil suit explaining why you couldn’t escape the situation. Mikey

        2. avatar Defens says:

          I think that totally depends on the circumstances. Shoot a muttering, gesticulating homeless dude at 20 yards, claiming you felt your life was in danger? Good luck with that. Shoot a dude that just jumped out of a truck, yelled Allah Akbar!, and downed a couple folks – from across the street, and depending on location you’ll be arrested, ignored by the media, or given a medal.

  3. avatar Tile floor says:

    I feel like having that on a gun as small as a Shield kind of defeats the purpose of it, it’s also one more thing to snag when drawing from concealment.

  4. avatar Geoffrey Hoffman says:

    Anyone know where to get slides that are aleady cut for the RMS? I see them for the RMR, but haven’t found any pre-cut for RMS. I just find places that will cut your slide to fit it.

    1. avatar Jeremy S. says:

      Try Lone Wolf. Call ’em if it isn’t on their site. I know I’ve been seeing RMS-equipped Shields and G43s on their Instagram feed and such.

  5. avatar Old Breed says:

    These work for me. I have 3 red dot sights on a m&p 9, Glock 23 and a cz-75 d compact. I carry each of these pistols both inside waist band and outside waist band with no problem. These give me back the accuracy I have lost over the years as my vision goes south. Difficult to get a good sight alignment and sight picture with bifocals. Would love to have a smaller red dot version for my commander size 1911.

  6. avatar TheSophist says:

    I’m seriously considering this. As I get older, I’m having more and more trouble with the front sight. A red dot might be the solution. I know it is for rifle and competition pistol; why not for carry guns?

  7. avatar Tony W. Ott says:

    As a company, Shield has never answered ANY communications I have sent via their website form or even direct emails.

    I own several of their red dots.

    Not great customer service to people who actually own their product.

    1. avatar Byron Horn says:

      I’ve communicated with the Shield company in the UK several times. The responses were always fast and
      always contianed all of the information I was interested in.
      As a matter of fact, they’ve been quicker to respond to the form (email form) than any of my regular
      companies here in the states.
