The XS Sights DXT2 Big Dot night sights for Glock put the emphasis where it belongs—on your front sight. Designed for shooters who need fast, reliable target acquisition in any light condition, these sights combine a high-visibility front sight with a low-profile rear, creating a simple, intuitive sight picture that performs when it matters. The distinctive large front dot draws your eye naturally and stays visible whether you're shooting in bright daylight, low light, or total darkness, making them a solid upgrade for defensive carry, tactical training, or duty use.
The DXT2 front sight features a patented photoluminescent glow dot that charges in ambient light before switching to tritium as darkness sets in. The yellow front sight is the brightest option available, offering maximum glow intensity and light absorption thanks to its convex shape and reflective properties. Paired with a green tritium white rear bar sight, the dot-and-bar configuration eliminates confusion during high-stress situations—your front sight is unmistakable. The 0.188" outside diameter Big Dot still fits standard Glock holsters, so you can upgrade your sights without retiring your gear.
These sights are precision-machined for Glock models 20, 21, 29, 30, 30S, 37, 40, and 41. Installation is straightforward, though your dovetail may require minor fitting; do not use a sight press tool. Whether you're building a reliable carry gun or enhancing an existing setup, XS Sights DXT2 Big Dots deliver the front-sight focus and low-light performance that defensive and tactical shooters trust.
