The most SubCompact Red Dot: Shield OMSsc

Pistols with optics ready cut prepared to accomodate Shield RMSc footprint standard are getting more and more popular. Although I personally prefer the manufacturer to give me some freedom when it comes to red dot options, not to be limited to subcompact sights with RMSc footprint, it makes sense when ti comes to subcompact carry pistols. 

The good news is that for such cases there are more and more red dot options that do make sense for the shooter. In other words, they keep up the subcompact size of the gun remain subcompact, even with red dot installed. The latest of them is the Shield OMSsc red dot sight. 

Dimensions

Skipping the obvious - the transparent acrylic roof of this red dot - I will get to the #1 main point of this red dot: its subcompact dimensions. 

• Weight 14.7 grams [to compare, Holosun K-series is almost double 28.4 grams]
• Length 40.8 milimeters 
• Width 19 milimeters [for example even compact sight Shield RMS2 is 20% wider with width 25 mm]
• Height 21.5 milimeters 

These numbers alone make it one of the lightest, thinnest and smallest red dots on the market. 

Mounting

Shield OMSsc uses the Shield RMSc footprint standard, for which you can find mounts and plates for almost any pistol out there.

However, the main use of this sight probably won't be on red dot mount or optics ready plate. Instead, it will be installed directly to the slide on pistols that from factory have the Shield RMSc footprint cut into the slide [such as Glock 43X MOS, CZ Shadow 2 Carry or P-09 Nocturne, and many others]. 

Nevertheless, if you decide to get this one for your gun that does not use direct cut, you can still mount it with the help of optics ready plate [for optics ready and MOS models], or with the help of red dot mount [for classic pistols].

Transparent acrylic roof of the OMSsc

And now to the thing that most probably catched your attention in the first place: the transparent roof of this red dot. 

Shield claims that the main reason for it is better visibility, and surprisingly even for me, it really makes a bit of difference. It makes the visibility better, and even improve the ambient light sampling.

Will transparent roofs be the new standard?

Most probably not. Although it looks very cool, something like driving a cabrio, it may be not as practical as hard roof that you get with the other red dots. But its really interesting thing to have on an optic, and I would love to get it even on larger sights for competitive shooting. 

Where to get the new Shield OMSsc 

As of now, time of writing in mid 2025, these red dots are mostly sold out as Shield has not been prepared for such interest from the shooting comomunity. Nevertheless, we have few pieces still on stock and you can get it on our website here: Shield OMSsc.
