CZ P-07 hammer play. Am I being too critical?

[wdbutcher]

I purchased a new P-07 a couple of months ago. Since then I've noticed a lot of side to side play in the hammer. My 2014 P-09 had no noticeable hammer play and my 2006 SP-01 definitely has no hammer play.
I contacted CZ USA and they basically said that the only way that this would cause a malfunction is if the hammer was dragging on the slide.
This is the email I received;

There has been no indication through extensive testing that the movement will ever increase beyond its starting point while all original parts stay in place, but should a malfunction occur we will be more than happy to bring in your firearm and repair it.  As mentioned before though, this hammer movement is fairly common and many thousands of P-07/P-09s in public hands will exhibit it. We have so far had 1 in all of those firearms where the hammer needed to be adjusted because it was rubbing the slide finish, and even in that particular case the firearm had no functional malfunctions. I am more than happy to bring in the firearm should you still like us to do so.

Thank you,

I sent my P-07 into them, knowing that some of the forum member had sent their P-07s into them and had them repaired.
They inspected mine and set it back to me without making any changes.
This bothers me a lot more than it probably should, but it looks like CZ's quality control may be declining. I would like to have your opinions if you think I'm being too critical.

I have .033" of side to side play with the hammer down and .045" of side to side play at the end of the hammer when it's cocked. I tried to include more pictures, but photobucket isn't wanting to work with me tonight.

My 2015 P-07 with CGW parts installed including their P-07/09 hammer has considerable side to side play. No I'm not going to drag out the dial indicator but if I hold the hammer to the far left then move it back far right it probably has .040 play in it. The gun has over 7500 rnds through it now with no issues what so ever. These are service grade guns so varying tolerances in some parts are to be expected.
Also it's not quite a proper comparison between the P-07 and SP-01 since they are 2 totally different guns even though both are CZ's. If the slop really bothers you you could buy some oversize pins and such and hand fit them to take up the slack. Personally if the gun runs reliably I wouldn't worry about it. Until we see guns malfunctioning more than usual I'm not willing to attack QC.

I really shouldn't have brought my SP-01 into the conversation since it's a completely different pistol. I was just surprised at how good the fit was on my 2014 P-09 compared to my 2016 P-07. Thanks.

I bought the new CZ-07 UG and sent it back to CZ-USA to look at because of the hammer movement, they sent it back stating it was within spec. It bothered me at first (a little OCD kicking in) but after having it checked out and everything was good, I don't give it a second thought.

Love the gun.............

If you're comfortable with disassembly, you could put a couple of thin plastic doughnut shims on either side of the hammer.

No, you shouldn't have to but it might help.  I sometimes use pieces of the thin plastic cutting boards.

That's a great idea, thanks.

Here's some more information on the same subject. This is an interesting post.

My P-07 as previously stated already has the CGW hammer and it exhibits no wobble during the trigger stroke but it does have side/side play if you physically grab the hammer and move it. There's no info on who the guy in the vid is or what experience in firearms he has. Just his opinion.

Isn't the person in the video "Joe L" from this forum? Sure sounds like him.

My video is referenced two posts above.  I offered it to show that not all P-07's have a wobbly hammer.  But this is based on my experience with a sample of 1 pistol.  If the trigger pull is consistent, and CZ says the guns are within spec even with some wobble, that is good enough for me, even though mine exhibits none.

My stock 2014 P-09 has no noticeable hammer side to side play or wobble. That's what made wonder why my 2016 P-07 did.
Joe, thank you for all of your great videos! They're always very educational and helpful!

Edit: My P09 does the same.

Doesn't wobble in DA pull, but hammer down or back I can wiggle it around by hand.

Hammer down it is completely centered. Hammer back I can't see between the hammer and frame on the left side of the gun. There is a gap between the hammer and the frame on the right side.

If I push the hammer to the right by hand and do a DA pull, it reduces grit to nothing. The other P09 and P07 I tinkered with at Acadamy sports both had a hammer that was aimed to the left like mine.

I'll run it as is. I think I'm at 200 + rounds. The second there is a problem I'm going to send it back to CZ.

I just watched that video posted, there is also no gap on the left side, but a small gap on the right side of the hammer, with no wobble during travel.
