Big Dot or Standard Dot?
XS Sights' Glock Sights are designed to boost accuracy and visibility for your everyday carry pistol. Featuring a high-contrast reflective white dot, these tritium sights provide enhanced low-light visibility with a glowing tritium center. Choose between two front sight sizes: the Big Dot (0.188" wide) for maximum visibility or the Standard Dot (0.140" wide) for a more precise sight picture. These express sights are especially beneficial for aging eyes or those with deteriorating vision.
DXT (Tritium) vs. DXW (White Stripe)
The shallow V rear sight is designed for a wider field of view and a low-profile setup. Select between a tritium bar or a reflective white stripe for rear contrast. Both options ensure quick sight picture acquisition and seamless alignment with the front sight. The rear ledge supports one-handed slide manipulations, making these Glock sights reliable in critical situations.
Sight Picture
XS Express Night Sights use a unique dot-the-"i" sight picture, with a tritium front dot and a rear stripe for easy alignment under stress. This design promotes high visibility and combat-level accuracy, ensuring a clear sight picture when every second counts. Built tough, these suppressor height sights fit most standard holsters and provide compatibility with suppressors or optics.
