CGW hammer for CZ 75B SA?

[manini]

Is it worth the money to install a CGW hammer in a CZ 75B SA? Would there be noticeable change to trigger pull/creep/break etc? Current is bone stock and is okay. Not expecting 1911 trigger. What is your experience? Thanks.

I just did a simple polish job on mine and removed the FPB. It made a good noticeable difference, to me at least. The reset is still pretty long though. I'll probably change out the springs and slap on a flat blade trigger. Then call it good for the internals.

Which hammer are you looking at?

If you are referring to the race hammer, here is my experience thus far.

I replaced my CGW Shadow hammer with the race hammer on my SA. With the CGW 13 lb spring my trigger pull increased from 2.5# to 3# but the reset appears to be shorter with a crisper break.

CGW says the Race Hammer and Ring Hammer are functionally the same with regards to the trigger. Supposed to take out creep and the break is cleaner like breaking glass.

I have installed the CGW comp hammers in a bunch of my CZ's at this point. It will remove most all if not all of the creep from the SA trigger pull. I depends on the specific CZ you are installing it in. Some of mine ended up with very crisp breaks some with a very short but less than crisp breaks. Due to the variance in CZ's from the factory they are all going to react a bit differently. As i understand it, his is in part due a variance in the position of the sear in different CZ's. Hammer spring weight can also play a part in the crispness of the break.

The hammer hooks on the comp hammer are much shorter than the stock CZ hammer. So regardless of the particular CZ the break will be short. In my opinion the Comp Hammer is the most valuable part you can invest in for your CZ. I would also suggest getting the adjustable sear for safety models, it will ensure that you safety still functions. It can also effect the SA trigger pull a bit.

Here is a closeup on the hammer sear engagement with the comp hammer. Take a look at the stock engagement on your CZ SA. You will notice how much more hammer hook contact there is in the stock configuration.

Thanks for the input. I have no gunsmithing experience but am reasonably handy. Changed out a firing pin once. How difficult is it to change the sear and hammer?

On a CZ safety model, while there is a bit of a learning curve its not very hard. There are many guides available for reference and you always have Calguns and the OG CZ forums to back you up. All in all, easier than they look.

I would invest in a starter punch (CGW sells them) to remove the factory hammer pins. The CGW hardened hammer pins are also worth the few dollars they cost. If you are only replacing the hammer you will only need one of these pins. With a bit of research before hand, things can be simplified. I would suggest asking before you force anything.

Here are a few good disassembly guides.

Thanks for the great picture. I can see a huge difference in how your sear and hammer make contact vs mine.

Update: Had a chance to shoot one with the CGW hammer thanks to another CGer. Wow. Nice. Clean crisp smooth break. This will be money well spent.
