CZ 75 SA question - hammer related
« on: July 12, 2017, 06:53:52 AM »
I had noticed earlier that my youngest son's CZ 75 SA did not have a half cock notch on the hammer.  Probably not a big issue since it only seemed to require extra effort when breaking it down for a cleaning (couldn't just put the hammer on half cock and move the slide back till it touched the hammer, you had to hold it different and visually line things up before pushing the slide stop partially out.)

He bought a "race hammer" a few weeks back and we installed that and even that hammer has a half cock notch.

Any reason why the factor hammers don't have a half cock notch, or was that hammer different and most folks with CZ 75 SA's do have a half cock notch on the hammer?

Just curious.  Being the only one I'd ever fooled with I just figured it was something to do with the SA design, till we got the race hammer installed.
Better to have it and not need it, than to need it and not have it.  So, if you see me walking the dogs with my SIG 556R, its okay.

I don't have an SA, but out of curiosity I checked an OEM TS hammer that I have and it has a half cock notch. I assumed the 75 SA used a standard DA/SA hammer since there isn't a replacement SA hammer listed on the CZ website.

I do not own a 75SA. All of my CZs have the half cock notch including the Tac Sport. This is the first i have heard of any 75 variant hammer without one. Was there a second hole in the CZ SA hammer for a disconector?

My TS .40 S&W has the aftermarket hammer installed in it (still) and it has a half cock notch, too.

I'll have to ask my son about the original hammer for the SA.  We put it in the zip lock bag, wrote CZ 75 SA hammer on the bag and he took it home with him.

edited to add:

Oh, that's nice.  All the years I've messed with M1 Garands and never got the M1 thumb.

I just got the TS .40 S&W out, was messing with it to look at the half cock notch and the full cock notch and cock it, let the hammer, down to the half cock notch, etc. and pinched the snot out of left thumb trying to drop it from full cock to half cock.  That trigger is just downright scary light/easy.  Right on the side near the nail.  Nice little blood blister.  Man did that hurt for a minute.  I'm make sure to NOT try to do that again.

It's the inside of the left thumb, not the right thumb, so working the safety on the CZ's is unaffected.  That's a good thing.

Thanks for that info.  So it's not just the one.

I wonder if all of them are that way?  And why the TS pistols (also SA) aren't made the same way (maybe no firing pin block on the TS is the difference)?

I just purchased a new CZ 75SA two days ago. Pistol is dated 2017. No half cock notch. My only other CZ handgun is a 2003 Kadet and it does have a half cock. :o

I wonder what the reasoning behind this is?

The CZ 75 SA has the firing pin block safety parts, but no half cock notch on the hammer.

The CZ TS is also single action only, does not have the firing pin block safety parts, but it does have the half cock notch on the hammer (at least on the competition/race hammer that was installed on mine when I got it.)

Curious that two CZ SAO pistols would be set up different.

My 2001 B-SA has a Half Cocked Notch in its Factory Hammer
Odd thing about it, the Hammer will drop from the HCN, when you pull the Trigger
So tell me again how Trump will be worse then the last 8 years !

I do remember asking this same thing. I have absolutley no idea why , but and I was told that some do and some don't .

I remember asking cause when I installed the race hammer in mine ( with notch ) I filed it down, as it could be dropped from half cock by pulling the trigger , which I did not like at all. It prob does not have enough momentum to set a primer off , but I did not want the confusion of a dropping hammer.

I probably needed to do some other modifiction to rectify this , but I remember I could not figure out any other way than file it down, and when I read that some do not have it I kind of relaxed a bit.

Mine is a 75B so it comes with a firing pin block . Since I had modded the gun myself I did not want to risk any accidents so I left the FPB in there. The gun worked flawlessly for hundreds of rounds so I am quite confident in it. But the FPB stayed. I bought all extra parts, so I can revert back to original state any time. It is a fun gun for the range , so I'm not too worried .
Shoot for fun and shoot safe !
