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.
