PreB no firing pin block

Tell me more about this - what does it mean as a practical matter - the PreB slide will be on a B frame. I know it works and works quite well.

I would guess that you wouod have to be rid of the extension on the sear which engages the FPB - if not, this etension would slam up against the slide and do no good to the trigger pull...

That sounds like a job for the dremel.

The ejector is what, wider on the newer CZs.  Don't have one in front of me at the moment, but I would guess that a PreB slide wouldn't work without some mods on a new frame.

Actually I fired about 100 rounds without problem - really asking about the safety aspect of not having a firing pin block and carrying loaded - cocked locked or hammer down cartridge in chamber.

Slide is getting a new front sight right now.

Thanks.

Hammer down, isn't as big a deal as some think (I used to think as well).  The firing pin is inertial, there is no direct connection from the hammer to the firing pin to the primer.

Cocked and locked isn't changed by the lack of a FP safety.

CZs were marketed for almost 20 years without developing a bad reputation for Accidental Discharges.

There is a small chance that the gun will discharge if dropped in just the right way, or if the hammer (if down) is struck with a lot of force.  But that's true of many guns in use today.

I'd recommend safe handling practices and just shoot the darned thing.

(I've had a number of pre-Bs.  They're nice.  But I prefer a well-gunsmithed "B" simply because there's no parts issues or mag issues.)

BTW.

You don't have to put a PreB slide on to get rid of the firing pin safety.  You can remove it from a B slide no problem.

I would be delighted to trade my pre B slide for a B slide if anyone is interested - I was not able to find a B slide but the pre b was pretty reasonable.

Hang onto it -- they aren't making any more of them...   (I've had ONE myself that wasn't attached to a frame.  They're rare.)

I bought the complete Kadet pistol for a practice gun then realized how much I liked it - had always heard of the Cz 75 and had fired one or two, but shoot Sig 226 and BHP for the most part. After spending a day shooting the Kadet and liking it I thought well now how about a 9mm conversion - CZ would not sell me one, so I just made my own (so to speak) - glad I did - I will try it in IDPA and see how it goes
