75 Series Complete Upgrade Spring Kit

Very popular USA made from music wire 13# hammer spring color-coded "blue". Must be used with our Reduced Power Firing Pin Spring.

Tempered spring steel firing pin retaining pin.  Our 61100 acts like a mini-shock absorber and can withstand repeated impacts from the firing pin.  Cushions the firing pin shoulder from damage.

Fits all CZ's that use a firing pin block system.

Installation note:  Always install the open end of the spring pin in the 12 0'clock position/facing the top of the slide.  A 3 mm roll pin punch is the ideal tool for removal and installation.

CGW's reduced power firing pin spring used on our 61050 extended firing pin.  Also recommended if you are going with a lighter hammer spring and retaining the stock firing pin.

CGW's reduced power trigger return spring reduces the DA an amazing 1/2 pound, yet still delivers a quick, positive reset.  CGW was the first company to offer an improved trigger return spring and our spring has been proven in years of use.

This CGW Made in the USA spring dramatically improves durability and reliability.  The known weak link in the trigger system is the factory trigger return spring that can 'snap' off the long leg of the spring = dead trigger.  Better quality music wire and a slight reduction in wire size equates to a much longer, if not indefinite life for the CGW spring.

A virtual must have for all CZ's that use this style trigger return spring.  Fits all CZ's that use this style spring.

Lite weight firing pin block plunger spring delivers a reduced trigger pull.
