Recently purchased a CZ Phantom. I broke it in with about 500 rounds and another 500 dry fires w/snap cap. While I'm very happy with the over all performance, I'd like to touch up the trigger pull. I understand replacing springs will help, but will a competition hammer work in the Phantom. Another problem I have is the curve of the trigger bothers my finger. It looks like the 85 trigger is flatter but will it work in the Phantom.
