Night Sights designed for defensive shooting and comfortable concealed carry. XS Tritium Big and Standard Dot Sights are designed for:

  • Snag free design for easy draw from holster without catching clothing
  • Large front sight to improve speed of front sight acquisition
  • V-Notch rear sight provides a large field of view for greater target identification
  • Tritium lamps aid sight alignment in low/dark light environments

Our night sights will allow you to get on target fast, focus on the front sight, and make a lethal/reliable shot.

XS offers sight options for all Glock handgun models including suppressor/optic heights.
