The standard "B" model allows cocked & locked, or hammer down with safety on.
My 75B's won't allow hammer down and safety on .... just like my 1911 won't allow it ... I just tested it ....
Also, just to clarify ... the decocker model is the CZ75
BD, not the CZ75D ... just in case someone does a search for it ...

Help me with a better understanding on this: If the hammer is down on the 75b and the safety cant be set on , is there a firing pin block that comes into play? Or is there a half /quarter cock position you use that allows the safety to be set?
Hey 3LD !
I'm looking at my 75B right now ... I don't know the mechanical internals of the firing system, so somebody else may be able to help with that, but I'll tell you what I know from handling the gun as we speak.
You CANNOT set the safety to ON with the hammer down .... (it's DA at this point, so why would you want to anyway ??)
You CAN set the safety to ON with the hammer cocked ... essentially 'cocked and locked' just like a 1911 ...
There IS a quarter cock position, that can be engaged by slightly pulling back the hammer until it clcks (about 1/4 inch), if the hammer had been down ... I guess this could slightly reduce the DA trigger pull, although I can't tell a big difference ... just a slightly shorter DA pull. In this position it definitely DOES remove the hammer from the firing pin at the rear of the gun.
I don't know how the firing pin is 'blocked' if the hammer is down on a live round, but I'm sure it is somehow, because that would be a very serious safety issue ... one that we certainly would have heard about ... as the gun has been in production for close to 30 years, and is the most widely used and distributed police and military handgun in history.
I don't use the 1/4 cock position at all (truthfully I didn't even know it existed until now), because if a gun has a safety, I carry it cocked and locked. This ensures that every single trigger pull is the same, as compared to the first one being a long, heavy DA, and the rest being lighter, shorter SA's. That can REALLY screw up your aim and your shooting unless you practice that way extensively. Usually when I carry, it's the G26 or the KT P3AT anyway, and they're DA all the time, so I know, and am ready for that.
Someone else may be able to help you with the technicalities ... maybe Cheese will chime in, or railroader.
