Short Reset System Installation Instructions
The SRS is designed for use only in firing pin block safety equipped CZ pistols. The SRS works equally well in manual safety or decocker CZ models. Once properly installed, the SA trigger reset will be reduced 40-50%. The SRS also cuts the DA trigger pull by up to 50%, depending on which hammer spring you select. For range and competition use, HS-12000 is recommended. For the ultimate in reliability/self-defense, use our blue 13# (HS-13) hammer spring.
CAUTION: The SRS will not work in the CZ Omega or Shadow, 85 Combat, or very early 75 variants.
CAUTION: The SRS will not work with the OEM firing pin.
CAUTION: All parts in the SRS kit must be used.
CAUTION: You cannot use the stock OEM 20# hammer spring with the CGW extended firing pin
NOTE: do not mix springs with OEM springs. You must use all the springs supplied in the SRS or miss-fires will occur. The parts included in each kit are listed below:

The CZ internal firing pin block safety plunger requires a minimum of 3mm’s of trigger pre-travel to fully lift the plunger for 100% reliable operation. This means the shortest in SA is limited to around 3mm’s. This distance can vary from pistol to pistol, with the most being slightly more than 3mm.
To measure the reset distance, you measure from the center of the trigger’s radius. Keep in mind, if your trigger has no over-travel stop screw, this over-travel after the trigger breaks will affect the reset distance. This additional travel is not actually part of the reset, but it can adversely affect the reset distance. The utmost in a short reset is attained with an over-travel screw in the trigger.
