The Shield Mini Sight Compact (SMSc) is an all new version of their RMSc built for Everyday Carry and singlestack pistols. The SMSc is built in a nylon glass filled polymer and has an option of a New Si02 Quartz hard coating or Glass Lens for extra resilience to the daily wear and tear of shooting. Its iconic design still allows shooters to co-witness with standard iron sights thanks to its incredibly low profile and unobtrusive design with rear iron sight notch. It carries on Shields philosophy to make its users better shooters by eliminating what is not needed and providing the shooter with just one point of focus. They dont have a large sight housing blocking vision, dimmed lenses, buttons to switch or backup sights blocking the view. They make their sights to fit as close to the bore-line as possible, where a trained shooter is naturally going to present their pistol allowing for a seamless transition and a familiar but improved shooting experience. Shield sights are made by shooters for shooters.Features :Parallax FreeOne 3V Lithium Battery, Cr2032Nylon Glass Filled PolymerCompatible With Night VisionDimensions, 1.7 X 0.9 X 0.94Moa Dot
