I installed a Dawson front on my CZ didn't like how small it is. Good for bullseye shooting at 25 yards+ but a poor combat site for 64 year old eyes. Installed TFX Pros, excellent combat but poor bullseye. Just can't win.

About the CM, so about $75 for the dovetail cut plus the sights plus extra mags. That's one of the reasons I always purchase the P series.
