Here is a shot of my Polished Stainless 75 (FPB removed) with the Cajun Gunworks Race Hammer.
It was necessary to clear the LPA low mount sights.
The Race Hammer is an excellent and easy fit. I also used the CGW adjustable sear and added the CZ Custom modified SAO trigger with pre-travel adjustment. The CGW trigger pin and lighter trigger return spring made installation easier. The 13# hammer spring helps lighten the trigger a bit too. Also I polished all the internal trigger parts and trigger strut per CZ forum gunsmithing instructions.
Thanks to David Milam at Cajun Gunworks and Stuart Wong at CZ Custom.
