Night Fision Sights G43/43X W/507K Orangenight Fision Co Witness Trit

Night Fision suppressor height sights for the Glock 43 and 43X deliver what pistol shooters actually need: a sight picture that works in sunlight and stays visible when it matters most. These aren't your standard aluminum-sleeved tritium sights. Night Fision's patented injection-molded sleeve design holds the tritium vials securely and creates what they call "The Perfect Dot"—a brighter, more durable witness ring engineered for maximum visibility in low light and full sun.

Built from high-quality CNC-machined steel and finished with Black Nitride coating, these sights are made to handle the wear and corrosion that comes with regular carry and training. The domed lens collimates the tritium rays for a sharper, cleaner sight picture. These are suppressor-height sights, meaning they'll co-witness with your optic if you're running a 507K footprint red dot on your Glock 43 or 43X. That matters if your dot fails or if you need irons in a hurry.

Night Fision's tritium is sourced from Switzerland and assembled in the USA. We recommend having a gunsmith install these; if you go the DIY route, review the installation guide carefully. Whether you're shooting competition, training for carry, or putting time in at the range, sights you can actually see—day and night—aren't a luxury on a pistol you're going to trust.
