can,t find anyone that carries them. It has the weird dovetail front sight with the pin in the side holding it in. any help would be great.

CZ themselves I am pretty sure they make them I have seen them on 75's and 85's but never got them for my own weapon.  I beleive trijicon makes them they will be pricy however.  You may vey well have to find manufacturer outside the U.S. as I beleive the 75 & 85 have only recently recognized for the excellent weapon they are, not a Browning HP clone.  

you can get them from trijicon, but you'll have to cut a groove in the front sight to accommodate the pin. Mattl is right though, they're expensive. Mine were $126 shipped

XS 24/7 sights come with tritium inserts for the CZ 75B. Check them out at XS Sights

I have the XS sights on my Kahr K9 and my CZ75B .40 S&W. AFAIK, they're THE BEST combat sight extant! I does take a little shooting to get used to them, but once you do, you'll have a hell of a time going back to the old school sights.

I have the "Big Dot" tritium on the Kahr and "Big Dot" standards on the CZ.

Regarding installation on the CZ, it's a no brainer... the sights come with easy to follow instructions. At most, you may have to do a little file work to get then pin to insert, but mine went in with a few taps aof a plastic hammer.
