XS DXT2 Big Dot Night Sights (brand part no. GL-0009S-5N) put an oversized orange front dot on a wide range of Glock pistols, covering the 17 and 19 through the 22, 23, 24, 26, 27, and beyond. The Big Dot geometry is built to stay visible even when a shooter’s focus narrows under stress, and the convex lens absorbs ambient light for a glow that carries well into low light. Orange offers a different visual signature than yellow or green for shooters who find it easier to pick up against their preferred background.
