I asked this same question on the CZ forum and the only answer I got was to contact Cajun Gun Works. The Omega trigger is a different design than the standard 75 trigger so my guess is that the SA trigger that CZcustom has (and which I have installed on my 75 compact) will not work. I have not contacted him yet but I might. I like everything about the gun except the trigger, and if I could get the trigger to where I would like it for $100 or so, the gun would still be a pretty good deal.
