Remember to always use a snap cap with CZs.
Why is this?
This was ONCE the case, but may not be necessary with newer models.
When the 75B was first introduced, the switch to a firing pin block included doing away with the firing pin STOP, a plate at the rear of the slide that retained the firing pin. CZ used a roll pin THROUGH the slide to retain the firing pin.
Repeated strikes when dry firing (which didn't impede the firing pin like a primer would) could -- but did not always -- lead to a broken firing pin retention roll pin. Back then I was a very avid CZ shooter and pooh-poohed concerns about damage; never had a problem with a 75B. But shortly after getting a 40B, I busted the firing pin retention roll pin, and became a believer. It was basically the same gun (internally) made in the same way. The replacement part cost $.75 at the hardware store; I only needed to cut a little off the end with a Dremel tool.
CZ later doubled the roll pin, and now uses a solid pin to retain the firing pin. If you have a solid pin (as is the case with the newer CZs), you can dry fire to your heart's content. If you've got a doubled pin, you probably can too. If you've got a single roll pin (easily noticed -- you can see an open spot when looking at the pin from the side), you might want to contact CZ and get a solid or doubled pin to replace it. (Or pick up some replacement roll pins at a hardware store -- which is what I did, as noted above, when I was doing CZs.)
It's only a concern with older 75Bs (and related models); less a concern with newer ones. But using snap caps never hurts anything. You can also use a rubber washer/grommet, also available at the hardware store. Find one that is about the proper diameter and thick, and insert it in the notch at the rear of the slide -- and that will keep the hammer from hitting the firing pin... Snap cap or grommet -- but with the older 75Bs, an ounce of prevention is worth a TON of cure, is cheap and a lot less aggravating.
