Just a heads up for those that own the CZ 97B. I wanted a safety that had an easy to engage lever and found that the CZ 75 Shadow safety fits. I also converted it to single action only and used a CZ Custom flat trigger and removed the hook for the DA. It's a rolling 2.8 pounds now and nice. The reset is a bit long (1/8 inch) but not objectionable. I also put the Shadow extended mag release in it. You must file or machine the end to a .295 diameter to use it but it works fine. Video to follow.
