XS Sights DXT2 Big Dot Night Sights for S&W M&P Shield - Green Tritium Front/Rear Set

The XS Sights DXT2 Big Dot Night Sight set is engineered specifically for the S&W M&P Shield family of carry pistols, including the Shield Plus and Optics Ready variants in 9mm and .45 ACP. Designed around XS's signature oversized front sight, the DXT2 Big Dot gives defensive shooters a fast, intuitive sight picture optimized for high-stress close-range engagements.

The Big Dot front sight features a self-illuminated green tritium lamp ringed by XS's proprietary photoluminescent Glow Dot in yellow. The Glow Dot absorbs ambient light and begins glowing before darkness fully sets in, keeping the sight working in transitional lighting conditions long before traditional tritium-only sights become visible. The high-contrast front drives the shooter's focus forward for the fastest possible target acquisition on a defensive pistol.

The rear sight pairs a wide V-notch with a green tritium lamp outlined in white. The open rear profile keeps the Big Dot front fully visible at all times, while still allowing the shooter to fall back on a precise index-style sight alignment when the situation calls for it. Tritium lamps glow 24/7 with no batteries, switches, or activation required.

Constructed on a CNC-machined steel body with a black finish, the DXT2 Big Dot set is a direct, drop-in upgrade for the S&W M&P Shield. Each set includes the front sight and rear sight as a matched, direct-fit replacement for the factory sights.
