The 71115 kit includes the "10040" hammer which is IDPA compliant. CGW gets this hammer from CZ Customs or CZ. It's CZC's comp hammer which has been used on enough production guns with CZ-USA part numbers to qualify. So O.P., if you have the hammer pictured on the CGW page for the "71115" kit, it's gtg for IDPA and USPSA.
This hammer will usually yield a slightly lighter and slightly less crisp break when compared to the Cajun "race" hammer. Away from the bench and on the range, they are very close in feel.
