Ok. I got it now. You can go to Cajun Gun Works or CZ Customs and get an OEM curved trigger for the 75b Omega that will match the same curve as the SP-01. I have a 75b Omega, but it came with a more curved trigger. It just depends on when you bought your CZ as to which trigger you got.
PS - If you do buy a new trigger, also get a "slave pin." It will help with putting all trigger pieces back to together.
