Product DescriptionUpgrade your Smith & Wesson M&P Shield with the XS Sights R3D Tritium Night Sights, engineered for fast sight acquisition in any light. The system uses a traditional 3-dot tritium, notch-and-post picture with a brighter tritium vial in the front and a green photoluminescent Glow Dot outline that absorbs ambient light for an extra pop in low-light conditions. A blacked-out rear with two green tritium lamps provides clear alignment without outshining the front, helping you stay focused on the target day or night. Built for duty use, these sights deliver reliable performance and intuitive indexing.Product Highlights Traditional 3-dot tritium sight picture with high-contrast green Glow Dot front for rapid target acquisition Blacked-out rear with twin green tritium lamps keeps attention on the brighter front sight Designed to fit the S&W M&P Shield for a clean replacement of factory sights Durable steel construction built to withstand daily carry and training use Front and rear sight dimensions optimized for a crisp notch-and-post alignment Specs Compatibility: Smith & Wesson M&P Shield Sight configuration: 3-dot tritium, notch-and-post Front sight outline: Green photoluminescent Glow Dot Tritium color: Green front and rear Finish: Black Front Sight Length: 0.440 in Front Sight Width: 0.145 in Front Sight Height: 0.282 in Rear Sight Length: 0.890 in Rear Sight Width: 0.800 in Rear Sight Height: 0.380 in UPC: 647533046558 MPN: SWR033S6G Brand: XS SIGHTS Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
