United Kingdom manufacturer Shield Sights is a pioneer in the field of electronic optics on handguns for competition and self-defense. While most of the company's contributions were behind the scenes, its introduction of the RMSc (Reflex Mini Sight Compact) brought the red dot into the mainstream for compact, concealed carry firearms. New for 2026, the company is bringing out its latest product, the OSMx, a micro red dot designed for competitive shooting.
The OSMx is based on the OMSsc (Open Mini Sight subcompact) introduced last year. The OSMc introduced the concept of having the top of the sight’s housing made of translucent acrylic. This allows the octagonal glass lens with a non-reflexive hard coating to gather more light and gives a cleaner and wider sight picture than what is provided by the lens alone. The remainder of the housing is made of T6 aluminum.
Like other sights in Shield’s lineup, the new sight gives the OMSsc the "x” treatment. This means a lens with an 80 percent greater area, intended for competitive shooters. The resulting sight is 1.61x1.34x1.07-inch and weighs one ounce. Like all of the company’s sights, it uses the RMSc mounting footprint. It is powered by a CR2032 battery, which has a 20,000 hour life in average daylight.
The OSMx is available with three reticles: a 4 MOA dot, 8 MOA dot or 2 MOA dot surrounded by a 65 MOA ring. Their brightness automatically adjusts to ambient lighting. All three versions have an MSRP of $490.
