Will a Omega top end fit a standard CZ75B SA, or 40B frame? Can pick the slide and barrel up for $125

That is a good question.

You may have to wander over to the CZ Forum and ask Angus.

I may be relaying bad info here, but I don't think the top-ends of the CZs are what makes an Omega model an "Omega." It's the fire control system, which is in the frame, that makes a gun an Omega. (If I'm correct, and that's just a standard top end, the slide and barrel would be a good buy for that price.)

As I understand it, most of the guns using the Omega system are the newer models which are not compatible with the older ones (i.e., the Kadet Kit doesn't fit on those newer frames. I think there is a newer P-02 (soon to be available here in the U.S.), a variant of the PCR, that would accept the Kadet Kit, though.

As suggested, talk with CZ (or the Custom Shop) to get a "for sure" answer.

AND LET US KNOW what you find out!!

I have a P02 I got from CZ Custom, it was really called a CZ Omega Compact.

Short answer, no I don't believe it will work. I am not 100% if the full sized Omega guns are the same as mine. You may be able to make them work together with some gunsmithing. The firing pin block is on the opposite side from "regular" CZ's. You may be able to disable the fpb since you have a SA model.

The frame and slide are the standard dimensions, but the trigger bar, sear, fpb, ejector, and maybe cutouts on the slide bottom are all different. Oh and the hammer is wider like an SP01.

Thanks for the quick replies! The guy bought it to put on a kadet frame, said to remove the fpb, but had really sketchy details... Oh, he super polished the barrel, and the serial#s dont match.... Think I just talked myself out of it:cool:

Now that you write those things, it makes sense. The standard decocker CZs have one of the hammer hooks removed to make room for the decocker mechanism; it seems that they'd redesign THAT way of doing things in a newer fire control assembly design.

The FPB on a CZ Omega Slide is in the same place as a normal CZ 75B

Here is a CZ 75B Stainless slide next to a CZ 75 Omega Slide.

The Omega top end fits the CZ 75B Stainless frame just fine. The inverse however is NOT true. The Omega hammer is quite a bit wider than the standard CZ hammer (not just the stainless hammer, I also checked a 75BD, an SP-01, and a Pre-B 85).

Here is an SP-01 Hammer:

now the much bigger Omega Hammer:

I wonder if the larger hammer represents a need for additional hammer mass, or just a convenient way to not mix up hammers during assembly.

hAkron, Thanks for going the extra mile on this! You cleared up a bunch with your pics!:)

So, the Omega top end would probably be a good acquisition.

(Some of the earliest CZ-75s had wider hammer than later models, and the newer Kadet Kits that would work on the 75Bs wouldn't work on all of the older models -- as the hammer wouldn't fit the notch on the back of the slide, and couldn't engage the firing pin. This was not a problem with most of the later 75s.)

The seller pulled his add on a local gun board, and listed on ebay or gunbroker if you guys care to search . He was really unclear about the details when I asked for pics, and I couldn't find it on either site.

The hammer on the 75 Omega appears to be the same width as the P-07 hammer.
