54420 Ultra-Lite Kit

A very popular and extremely effective upgrade.  Tens of thousands are in service worldwide.  Fixes the minor design issue with the factory firing pin.   Combined with our shock absorbing spring steel retaining pin, reliability is greatly enhanced.  Reduces the heavy factory DA pull weight nearly 50%, yet retains reliable ignition when using our “blue” HS-13 hammer spring.

The HS-13 music wire hammer spring is for defense use.   HS-12000 “black” hammer spring will cut the DA about 60% and will set off “most” primers, ideal for range and competition when using Winchester or Federal primers only.

Installation Instructions

Lifetime warranty on the CGW hard parts.





Tutorial for All CZ

TECH TIP:  We suggest a 3mm roll pin punch for removal of the firing pin retaining pin from the slide.  Use this same punch as a guide for lining up the flats on the firing pin, then drive in the new CGW 61100 tempered steel firing pin retaining pin from the left hand side.  Be sure and orient the 61100 with the open end “up” at the 12 0’clock position.
