One of the weak links of the CZ 75B model pistol is the mild steel OEM firing pin retaining (roll) pin. Here is a photo of a factory pin that has been damaged from repeated dry firing. Had the original owner continued dry-firing this pistol, it would have only been a matter of time before the other side of the pin fractured, resulting in a full "shark bite" which would have disabled the pistol. When dry-firing a CZ 75B model, snap caps are highly recommended. Should one require a replacement pin, Cajun Gun Works offers a tempered spring steel pin (item 61100) which is designed to withstand repeated firing pin impacts.

I'm a big CZ 75 fan, but probably my biggest pet peeve w/ them are their relatively fragile firing pin block retaining roll pins. The CZ recommends replacing them every 5K rounds.

This is what I use. Rubber o-rings cost pennies. My o-ring of choice is 3/8" inside diameter X 9/16" outside diameter X 3/32" width, but anything close will work as long as it fits securely in the back of the slide where the hammer strikes.
