I searched the upc and other sites selling this model incorrectly listed them as luminescent sights..
But CZs website clearly says "tritium night sights"

This Pistol features luminescent sights, which are a form of night sights but they do not feature tritium, tritium night sight will illuminate for 10 years with no external light source required, luminescent sights require light exposure, they need to essentially charge before they'll glow in the dark, this is like the glow in the dark bracelets kids wear on Halloween.
