night sights?
you bet man. trijicon makes them for the cz75. i have them on my cz. call trijicon (web search for trijicon and it comes right up) and ask for the dealer in your area. if no dealer you can also buy direct from trijicon. they cost me 100 bucks for the set (about the average for all tritium sights). they are a great improvement.
they fit in the factory sight cuts, but i still needed a gunsmith to fenagle them in with a little dremel work.
good luck.
