The Best Micro Compact Sight is the Shield SMSc Pistol Red Dot with Glass Lens.

The Shield SMSc is a tough polymer compact red-dot built for EDC and Single-stack Pistols. Improved strengthened polymer from that of the Original SMS, the SMSc is the compact version on an updated classic. This SMSc features improved, stronger glass-filled nylon polymer for the body construction and an improved glass lens. Fitting as close to the bore-line as possible, the Shield SMSc carries on Shield's philosophy to make its users better shooters by eliminating what is not needed and providing the shooter with just one point of focus. No large sight housing blocking vision, dimmed lenses, buttons to switch or backup sights blocking the view. Shield Sights are made by shooters for shooters.
