Decocker Hammer Installation Instructions

If you are not familiar with the procedures to disassemble and reassemble your CZ pistol, it is recommended you find a competent local gunsmith. You can also send your CZ to CGW for installation if necessary. Disassembly help can be found on the CGW website home page, see the “TUTORIALS” for dis- and reassembly of your CZ.

Before installation, ensure the pistol is unloaded. Always point the muzzle in a safe direction.

Please note the 75 series decocker CZ is the most difficult CZ to disassemble and reassemble.  If you have viewed the CGW decocker website tutorials and do not feel comfortable installing a performance hammer, contact your local gunsmith or CGW. 

  • CGW’s installation kit for decockers, part number INST-DC contains a sear cage slave pin manufactured just for the CZ decocker sear cage.  Reassembly is not possible without this slave pin or a slave pin made to the same basic size.  A special 1/16” starter punch is also part of this install kit.
  • New hammer pins, CGW part number: HPIN are highly recommended.  Please note the CGW HPINS do not need to be staked when used with a CGW hammer.
  • Reinstall the hammer strut and disconnector onto the CGW hammer.  Ensure the pins are flush with the sides of the hammer body.
  • Install the CGW hammer assembly followed by the sear cage.
  • Reassemble the pistol including the slide assembly.
  • Check the pistol for proper decocking.
  • Check the pistol for proper SA and DA trigger function.
  • The SA trigger pull should be significantly improved compared to the original hammer.
