Shield Sights Announces the RMS-W Red Dot Sight

Dorset, England, U.K.-( Shield Sights is pleased to announce the release and full production of the RMS-W. The RMS-W is the water-resistant and ruggedized version of the existing Shield RMS line of sights.

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.

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.

    1. Literally EVERYONE who owns any of the now 3 iterations of the Shield RMS, me included, have had only one complaint about it, the lens. Why is Shield trying to reinvent the wheel with these hardcoat super special whizbang polymer garbage i stead of just making the lens glass?! There is a significant reason EVERY other quality red dot uses glass NOT polymer. Any piece of cloth laying around will perfectly clean my RMR while I have to run a cover on my RMS and use m.e.k. and Johnson cotton buds from the U.K. just to wipe a fuzz off and it still scratches. I LOVE this sight on my S&W Shield and no other sight comes close to the performance and more importantly, the size of it, that has a glass lens. Just make the lens glass and be done with it already! No one running this sight is doing so in such an abusive manner to break the lens, and even if they are the integrity of the housing is going to go at the same time, or more likely before, the lens which makes the sight unusable anyway.

      1. Thanks for your comment. I was blaming myself for scratching the lens even though I treated the Shield the same as my other red dots.

    2. I’ve been running a Shield RDS on a Glock 43 for about a year. Function has been good. I have noted the lens has scratched up despite my attempts to avoid that, so a better coating would be appreciated. It’s an always on sight and it’s needed 1 battery replacement in a year. Its small size is really appreciated on a small pistol.
