Hammer rub

[Rowe-75]

I was doing some research on the insert issue and I stumbled across something else which I believe explains the horrendous DA pull on my P07. The hammer is not centered, the left side of the hammer is rubbing on the frame insert. It was a 2009 post at THR that talked about this but a solution was never mentioned. Here's the link, near the bottom of the page is where he discovered his problem with the P07 trigger. This is definitely what is causing the binding in the DA pull because if I push the hammer to the right side of the frame while pulling from DA it is smooth as butter with no stacking or binding. Does anyone have a cure for this, short of trying to return the pistol? I would like to get this pistol running to where it should be but I am not very confident with a total disassemble and gunsmith work.

It may sound like I am nit-picking this pistol but I am not. If you could feel this DA pull as-is, then push the hammer over and feel it, it is a world of difference. It is a very smooth, clean breaking pull when it isn't rubbing on the frame.

Will just polishing the side that is getting worn do the job?

If it were me

I would probably polish the side of the hammer and the both sides of the insert to add some clearance and reblue the parts.

also I would check the fit of the hammer pin to the hammer and see if there is any room for the hammer to wobble or if it is sitting square in the frame.

I just looked at a few of my pistols. A couple of Sigs, a S&W, and a CZ. Not one hammer was sitting exactly centered in the frame. The torque and pressure of the hammer spring and the necessary clearance to allow the hammer to rotate around the pin are going to cause it to sit to one side or the other.

Just my 2c.

If I were to try and polish it to where there is no contact between the hammer and slide, I believe I would have to move a bit of material which I am not very comfortable with.

Widge, I check my 75b, the hammer is centered, 40b the hammer is very slightly to the left but still moving freely, the P07 is pushed up against the frame and has pressure holding it to the frame. The picture doesn't do it much justice, there are gouges in the hammer. I believe the DA pull would be fantastic if the hammer wasn't binding on the slide. Trust me, if you could come dry fire it once in DA mode you would say "that is unacceptable". I guess I should contact CZ about this.

Hey, if you think it isn't right, then give them a call.

ya from your picture it doesn't look like there is any room to move it even if you took it apart and to try to reassemble it more to the right seems like it made to fit without and space between them. I would call CZ and tell them your trigger is messed up and that you think it could be because of the hammer. The will probably tell you to shoot it til it wears the hammer down like they told me with my rear insert, so good luck with that. CZ needs to fix things if they are not manufactured the way they are designed.

I just bought a brand new 2015 P07 and I am having this same iasue. The SA feels great, DA feels clunky and gritty. If I push the hammer to the right while dry firing in DA, it feels smooth. I have read quite a few similar posts on different CZ forums where P07 owners had the same issue. One guy said he called CZ and they had him send it in and they fixed it under warranty.

I was seriously considering going back to a gen4 Glock 19 but I really wanted to give this gun a shot. Now I'm pretty disappointed. I have owned around 30 pistols,  and have NEVER had this issue. I thought if any gun has a good trigger and is quality made, it would be a CZ. After all the posts of this problem, and to know that the problem still persists...

CZ-USA will take care of it if indeed there is a problem. Give tem a call. By the way if you've bought 30 pistols and never had an issue with one consider yourself very lucky. I've had issues with Cz', Colt', Sig, Springfield, even a bad Glock so it happens to them all.

I can't see the photos, so I'm guessing about the contact area.  If you remove the hammer spring and remove the slide, you can feel where the roughness is by moving the hammer back and forth through its normal travel range.  Then remove the hammer and smooth the hammer and the frame as Stuart suggested.  Reassemble and check.  I bet you have just a sharp edge on the frame parts that is causing most of the drag.  I've had to do this on a P-09 and a CZ-97 and a SIG.  The manufacturers try to keep the clearance tight so that the hammer is in exactly the same position each time the sear engages it when the hammer is most rearward, I think.  Sometimes burrs or tolerances add some drag, that's all.  Easy fix if you remove the hammer.  Videos here.

Another thing to check is the hammer strut.  I had one that had a little bend to it near the top, causing it to be in a bind installed in the gun as the hammer traveled.  While you have the hammer out, check to see if the strut is straight with the center line of the hammer and not pointed off to the side slightly when you hold the hammer vertically and look at the alignment from the back with the hammer and strut hanging straight down.  Another easy fix.

I had a slight bit of drag on my P-09. I could feel it and see the hammer rubbing on one side of the frame.

A few strokes with a small file on the plastic frame and it is smooth now.

If yours is really bad I would send it back, otherwise it is an easy fix.

Of course I have had issues with other guns. Just never THIS issue. And most of the guns I bought new functioned properly.

12 posts in 5 years about this issue from two members of over 26000 in a Forum dedicated to CZ pistols hardly constitutes an epidemic.

My p07 hammer has rub marks on both sides. Mine is a duty with an 09 build date. On things like that where it's just the d/a pull I just let it wear itself till the action was smooth. I bet 95% of the time the pistol is being shot in s/a.
