Shield Sights RMS [Reflex Mini Sight]: RMSc, RMSw and reviews

The first of the Shield Sights RMS series came out circa September-October 2016. The original Shield RMS was very small, though not as small as subsequent RMSc (q.v.).  All the RMS line is descended from the British CQB, which saw extensive service with MoD and other Commonwealth forces (and from the CQS, which was the civilian version of the CQB).

The glass coated polymer lens ads no magnification or distortion to light that can be found in other options on the market. An all-glass lens will be available by the end of Q3 giving users maximum resistance to scratching. The glass lens is in the final stages of testing.”

Reflex Mini Sight

The RMS is described by the manufacturer thusly:

Parallax free, clear polymer optic, which can withstand up to ten times greater shock impact than products using glass optics. Unlike many competing products, the RMS is designed without a red reflective filter on the lens to ensure minimal visual signature. The sight body is made from aerospace-grade aluminum and has an anodized matte black finish. Variable intensity drive circuit that senses target light levels and controls LED output giving optimum visibility of the dot against the target. Available in different dot sizes, tailored to your application. The RMS fits all mounts readily available for the SMS. The RMS is available with an optional battery draw that allows you to change the battery without having to unmount the sight.

Shield RMSc

Released in early 2018, the RMSc (or RMS-C) is the…wait for it…RMS Compact. Originally intended for sub-compact pistols like the Glock 43 and S&W Shield, the little red dot sight has seen wider use with the advent of new types of sub-compact handgun.

The RMSc was released with the same bolt pattern as the original RMS (and for that matter the first Shield SMS). This allowed users with RMS-compatible slides to switch to the RMSc without undue hassle. A side accessible battery draw also allows for quickly changing out batteries.

The Shield RMS series is an increasingly popular option for the smallest of concealed carry pistols.

As red dots for pistol use became increasing popular some manufacturers began releasing handguns already so equipped: like this Walther PPS M2 equipped with an RMSc, reviewed on Shooting Illustrated.

Shield RMS-W

The Shield RMS-W (also referred to as RMSw) is a “ruggedized” and water-resistant version of the Shield RMS.

Shield Sights RMS-W

According to the UK-based manufacturer, “The Shield RMS-W is designed to resist damage from water or other harsh environmental conditions.  The RMS-W is gasket sealed to create a watertight fit between the slide and the battery compartment without the need of a special mounting plate.  When the sight is properly mounted it will remain watertight at depths of up to 20 meters for 30 minutes.”

According to the original release (c. December 2018), “The RMS-W also features a newly designed frame which adds thickness to the aluminum lens housing as well as a newly designed side profile.  The RMS-W will also be the first sight in the RMS line to benefit from the newly developed hard coated polymer lens.  These modifications have increased flex strength of the standard RMS sight by over 80% while maintaining the original viewing window and mounting footprint. The RMS-W will fit any slide that has already been cut for the RMS, RMS-C, SMS, or Jpoint.”

Shield RMSw Specs:

– The RMS-W is machined from aerospace grade aluminum
– Gasket sealed to ensure consistent waterproofing
– Increased thickness of aluminum housing
– Hard coated polymer lens to resist scratching
– Very fast automatic brightness adjustment
– Very low profile to Co-Witness standard iron sights
– 2-3 year average battery life with standard CR2032 battery
– Weight: 17.6 grams / .62 ounces battery included

 

Shield RMS Review (s)

 

RMSc Review – Springfield Hellcat (Mike Humphries)

“I have to admit I really like the Shield RMSc on the Hellcat OSP. The combination of the compact little red dot with the excellent U-Dot iron sights of the Hellcat gives me a great combination of options. I have the red dot right there whenever I need it, and I also have the irons backing it up in case anything happens to the optic.

I personally have had trouble in the past with red dots on handguns with finding the red dot in the sighting pane — basically I would have to search a little bit to spot it. On the Hellcat OSP and the Shield, I use the co-witnessing U-Dot iron sights to get me “in the zone” for the first fraction of a second. By starting to align the iron sights like I would with a normal pistol, I get the gun aligned properly so I can quickly pick up the red dot. The more I do it, I find I’m automatically aligning the pistol on the target to see the red dot without having to even think about the irons. As with everything, practice makes perfect.”

RMS Review: The Firearm Blog (Nathan S.)

“Typically, I am wary of self-adjusting optics. Almost invariably, those models have major issues from shooting from dark light into high light and vice versa. The Shield RMS did not – if only because it defaults to being a bit brighter than one is used to. This leads to some fuzzy outline on the dot when shooting into low-light, but not so much as to be distracting. Its bright that the 4 MOA goes to 8. On the converse, the optic is bright enough in low-light that shooting to high makes the dot a fine circle. While not tested with night vision – Shield states the dot will adjust to night-vision compatible in suitable environments…

TFB Review: Shield RMS “Reflex Miniature Sight”

…Putting rounds down range is as easy as put the sight on the target and pull the trigger. When using the Glock front sight, I especially liked the rear notch. As one who practices finding the dot by establishing the iron sight picture, the integrated sight is a real benefit. Even re-mounted with the taller aftermarket sights, it worked well – I just did not like the taller irons taking up more of the sight picture – not the fault of the RMS.

As with any sight mounted to the slide, it takes practice to follow the dot during recoil and reset for follow-up shots. At first, the bouncing red dot is unnerving, but with a hundred rounds down the pipe, it becomes comforting to watch the weapon’s behavior and track the dot back onto the target – a big boon over standard irons which require getting the rear sight back into focus as well. For close-in targets, I did not see much improvement in splits or accuracy, but targets 15 yards and out, the RMS shined bright like the red dot.”

Shield Sights Review: TTAG on the RMS (Jeremy S.)

“Thanks to the polycarbonate lens, there’s no distortion or color shift when looking through the RMS. It doesn’t require a red coating and gets only an anti-reflection and anti-scratch treatment. Glare and “visual signature” from downrange are reduced as compared to a glass lens RDS. Additionally, the polymer lens is both lighter weight and more impact resistant than glass. It falls short vs. its glass brethren only in scratch resistance…

RMS review on The Truth About Guns

…A light sensor in the RMS adjusts the dot’s brightness automatically. And very well, I might add. For instance, if you’re in deep shade but your target is in full sun, the sensor does a good job of recognizing the brightness of your target area and adjusting the dot accordingly…

…I think the SHIELD RMS is the best micro red dot sight on the market, or at least as good as it gets. No buttons, no settings, it just works and works well.”
