A Shorter CZ DA Reach?

schmeky · Feb 2, 2011

It would be hard to argue CZ's aren't at least pretty good. But there are 2 main complaints, IMHO:

1) Pretty crappy SA trigger
2) DA initial reach is to long

I have found a way to decrease the static or initial reach to the trigger in the DA mode. This mod also reduces the DA stroke. I have attached pics to show the difference. Basically the reach is decreased by 4mm. The felt difference is quite dramatic.

After:

Similar to what Angus at CZ Customs.

Isn't the pistol in the Custom shop photo "single action only"?

schmeky,
That looks good. I would definitely like to know more about it.

Yes it is. My comment was that it is similar to what Angus does. Did not say the same as Angus does... LOL

I too would be interested in what was done to the gun.

Yes......do tell........

Schmeky, do I see a shim in the trigger 'notch' next to the frame?

schmeky · Feb 3, 2011

1SOW,

Yes, that is a shim I used for the initial set-up, now there is a 4-48 set screw there that allows adjustment and fine tuning. The set screw will be permanent.

Rellascout,

Will all due respect, I believe your talking apples and onions, your pic is a SA with a SA trigger. Mine is the traditional DA/SA version with the stock CZ trigger.

Basically the internal disconnector is modified and the trigger is repositioned to take advanage of the room the disconnector affords. Actually pretty simple.

The difference in reaching the trigger is significant, here's a before, the tip of my trigger finger is hitting the inside front of the trigger guard and I can only touch the side of the trigger:

Here's an after, and I have long fingers, feels much different now:

viking499 · Feb 3, 2011

Is that something anyone can do or does it require special techniques/equipment?

schmeky · Feb 3, 2011

Viking499,

If you're very mechanically inclined, and can drill and tap (the trigger), you could probably do this at home. I did the disconnector on my mill to ensure exact and even dimensions on the finished disconnector.

Maybe my comment was not clear or detailed enough. My point was that is looks like you were able to get a similar distance in trigger length with your DA/SA gun that Angus is doing with SA guns. If you look at the pics your DA/SA trigger position is very close to his SA. That is a good thing. I am not sure why my comment is being taken as if it was a negative or a slight. Is that better?

Seems like this is a modification which would require milling and might not be something the avg gun can accomplish but keep us updated. I agree the length of the DA pull is an issue for many people with the CZ 75B. It is the reason I sold mine.

Next time I pick up a CZ 75, I might have to let you try your handy work on it. Can call it the "Schmeky Custom".

Can you do the same thing with the recurve trigger and shorten the distance with it also?

True, true, you did not; I was just wondering if they were doing something that I missed. :uhoh:

Thanks for the reply

I wish they would. I love my P01 but I had to sell my 75B long ago because it simply did not fit my hand well enough. I constantly found myself shifting my hand when shooting it in DA.

The P01/compact/PCR all seem to work for me better than the full sized 75B line. I have not checked out the SP01.

viking499 · Feb 3, 2011

Can the same mod be made on the P01 or other compacts?

I surely did not Rellascout

I have great respect for your input.

The internal lock works on all DA/SA CZ's are identical, even most of the CZ-97 internals will interchange with a CZ-75. So yes, it could be done to the other CZ models as well.

I did at one time manage to accomplish a recurved trigger that made some difference, but it was impractical to do it on a consistent basis.

The CZ trigger is very thick, overly so. I think you could easily remove an estimated 1/8" or more from its forward curve. Combine this with the mod I have done and you would have a CZ with a DA trigger in the right location. It would completely change the feel and greatly improve the DA feature.

I am glad my comments were not taken negatively. I am very interested in what you did. I had all but given up on the 75B being a gun in the stable but now you have me thinking... LOL

I think you should find someone to manufacture the part for you and start a side business!

How does it effect the trigger feel?

Shadow 7D · Feb 3, 2011

Check out the Israeli BUL pistols, it's a Jericho/ baby eagle (based off the TZ which is based of the CZ...)

I read the reviews that say that it's the most ergonomic grip of the lot.
I think Southern Ohio Guns has a lot in.

The trigger feel is unchanged, however, the disconnector mod shortens the full DA stroke by about 15-20%. I have been testing the DA using a 15# hammer spring and primer hits are positive and consistently deep, even with the reduced stroke. Makes for a quicker, snappier DA.

Funny you mention this, my incorporation paperwork is on it's way to my States Secretary of State. I plan on offering some CZ drop in trigger kits, drop in DA parts, and other things, as well as doing work in my machine shop.

I am looking for a cutter and working on a jig for cutting the stock triggers from 3mm, down to about 1.8mm in thickness.

I knew that when I saw the pics in this thread that it was going to cost me some money somewhere down the road. I guess I have time to save up for it.......

If the "Heggis Flip" can be a universally accepted mod for the Browning Buck Mark, I think the "Schmeky Trigger Trick" might be appropriate for CZ...

tekarra · Feb 3, 2011

schmeky,
Very interesting, and I am interested.
Looking forward to reading more as you develop your plan.

schmeky · Feb 3, 2011

tekarra,

Thanx a bunch for your input. I am pretty confident at this point I can supply a 1.8mm thickness trigger and an accompanying machined disconnector in the very near future.

This should easily reduce the static DA reach by 5+mm, a significant improvement. I want to provide a cost effect solution to the overly long DA reach, a long standing complaint on an otherwise very good pistol.

Be on the lookout soon for Cajun Gun Works

Stringfellow,

I really like your comment (Heggis Flip is a little over the top IMHO) . . .

viking499 · Feb 3, 2011

schmeky, will this also work on the PCR and P01?

Would you mind linking it to this thread. I don't want to miss it.

viking499,

Yes.

CZguy,

Yes sir, will do.
