Spare parts for CZ-75B


March 5, 2004, 11:56 AM
Since CZ-75 parts are not as readily available as those for 1911’s, I’d like some opinions from the experts on what spare parts should be kept on hand to make sure that it can be kept in action. Below are the parts that I think are needed. What else? Other thoughts?

1. Springs: recoil, main, firing pin
2. Firing pin
3. firing pin retaining pin (dual roll pin)
4. slide stop
5. lots of standard cap magazines and mag springs.

Slidestop and extractor

CZ-75, or CZ-75B? There is a subtle difference.

For either gun, springs are availble from Wolff.

The new model slide stop and extractor work in the older guns.

Recoil springs don't break, neither do extractor springs -- they do begin to function less well. Extractors may eventually wear, but you'll likely know before the gun fails.

The older model doesn't have a firing pin retention roll pin. And I've not heard of one of the "doubled" pins breaking. If you don't have a "doubled" pin installed in your newer B model, and it breaks, you can fabricate one (with a Dremel) from a roll pin available at your local hardware store. Cost?
Mine cost me $.15.

Except for a strange little spring inside certain of the older (pre-B Model) 75 safeties, most of the new parts work in the older guns. (Hammer widths changed over time, so they are NOT all interchangeable.)

You can get quick turnaround from CZ-USA.


Keep on hand those things you can't wait a week or so to get directly from CZ.

Slide stop, maybe?

one doubled-roll pin, maybe?

For sure, get an upgraded (extra power) extractor spring from Wolff. (Its a new part, and its an immediate upgrade, not a "replace when the other wears out" sort of change.)

Many have found the slide stops to be weak items on the 75 design guns. My CZ 75 IPSC Standard came with like five extras... directly from CZ... Not a very comforting thought.

I've put many rounds through EAAs and CZs and have fortunately never had an actualy physical failure... no breakages. But I tend to keep an eye on pins and such. Never shot any of them enough to replace any springs either.

Guess I'm lucky, eh?

from what I have seen, in order of importance.

slide stop
extractor spring
recoil spring

one spare of each will likely keep you functioning for quite a while provided you are spreading all that shooting over a number of magazines.

Thanks, I forgot about the extrator. D'oh.

cratz2, have you looked at the slide stops? They should be of different types I think (different functions).
I agree with them beeing one of the few weak parts in the CZ though.

Yup, slide stops, recoil springs, +5% or +10% mag springs from wolff, extractor springs, etc.
I guess the witness slide stops are an improvement, if you get the right ones.

Witness slide stops, as best I can tell, do NOT let the slide lock back after the final shot, when installed in a CZ. (That is second-hand information, but I've heard it consistently.)

If that is not an issue, get a Witness stop.
