P09/07 thread on potential major issues

https://www.m4carbine.net/showthread.php?209390-PX4-CC-vs-CZ-P07


In this thread it has been put out as fact that many P09/07 when you pull the trigger the hammer goes to half cock.

"CGW is curently working on a fix, and so far, CZ has ingnored the problem"

" When CGW went through about 10 stock 07/09's they had on the shelf, 7 out of 10 did it.."

I have been here for sometime and have never heard or seen this issues.

I would like like to hear what CGW says about this so called issue.

Never heard of this either

If CGW had run across this wouldn't they be mentioning it here?

As many P07's and P09's as members here purchase/use wouldn't someone have run across this if the numbers were 7 of 10 = 70% of the new pistols malfunctioning in this manner?

Mine are 3 to 5 years old.  No issues.

I glossed over that thread briefly but won't waste my time reading the whole thing. Perfect example of how things can get blown completely out of proportion by misinformation on the internet.
I believe the oversize DA rollers that CGW sells are the item that cures the hammer drop issue which is blown way out of factual proportion in that thread.
My P-07 in stock form was flawless out of the box and I ran it through 1000 rnds before upgrading to CGW springs and a hammer.
The gun was flawless for about 2000 more rnds and after wearing in real good it would drop to half cock during a light and slow pull from SA.
Talked to David at CGW and measured my original roller which was a tad egg shaped .215 and .218. I installed the CGW .220 roller and the gun has been flawless through nearly 7000 rnds since then.
Had I left the gun stock I suspect it may have never had an issue but when modding guns this is what you can encounter and I find it to be an non issue.Nothing wrong with these guns.

None of my 07s do it. My 09 does the half cock thing after I replaced the roller, but only if I stick a small punch behind the trigger and slowly slowly slowly slowly press the trigger.  I haven't been able to make this happen during a normal dry fire session or live fire. 

To me this issue is similar to riding the slide stop and not having the slide lock back on an empty mag, or limp wristing

I followed the thread, this came from over at pistol training.com  The way I look at it, if CGW  is developing parts to correct this, then clearly, they think it's a serious enough issue.. In the mean time, my P07 is sidelined to range duty until this is cleared up.. But like it or not, the issue does exist, and is something we all should be aware of, if and when your pistol does start to do it. Right now, the root cause seems to be clear as mud.. In short, I would'nt just blow it off because your pistol dosen't do it...

We have zero evidence, that anything that has been alleged about P07/09 issues are as serious if it exists at all as what is being stated as fact on other forums.

I am waiting for CGW to respond so that we can get a feel for what they have observed.

My P07 is still my go to pistol and will remain so. I have shot Hi Powers to breaking point and I have had Glocks fail, so mechanical things fail at times big deal.

The 41pg. thread spans a 4 YEAR period. This NONSENSE is being revived by people  out of ignorance. CGW developed the rollers to correct those issues a couple years ago.
Hopefully David at CGW will respond here and clear up this malarkey.

Had a P-07 DUTY, never had an issue like that. My Cajunized P-09 has NEVER ever done that.

You're on the wrong thread then. The one with the issue is from July

Then post us the correct link if you would please.

I think this is the post that explains it best

Folks, I think I've solved the mystery.

Quick summery: The issue is caused by the way you pull the trigger to the rear, and has nothing to do with lateral force on the trigger. I believe the issue is caused by activation of the drop safety mechanism, and is not a design flaw in the gun.

I can now replicate the hammer dropping to half cock in both of my P-07s. If I interrupt the rearward force and motion of the trigger at about 75% of the trigger stroke, the hammer drops to half cock. Lateral force on the trigger is not required, nor is orientation of the gun. It's all about the trigger pull.

If you want to try this: hook your finger deep into the trigger so the pad of your finger gets pinched between the trigger and the frame, stopping the trigger. Then continue to pull.

A lighter hammer spring makes it easier to do.

It is easiest with no hammer spring installed. Just manipulate the hammer by hand while playing with the trigger. That's how I figured it out.

Bottom line: I do not think this is a problem. The gun is functioning as designed.

Might want to go to pg28, read posts #273,274,278, I would suggest that one should read the entire thread to get a feel for what's going on here, if you think it's bunk, then carry on...

So that is a different thread altogether. Interesting but my P-07 exhibits no issue left handed,right handed or pulling trigger with either big toe so I'm not concerned about my gun.  I'd still like to hear from CGW on this but I will also be keeping in mind they are in the parts biz.

So would I, there is alot on conjecture on this issue, and right now the root cause is clear as mud..So, for the time being, I'm going to sit back and see what develops here, in the mean time my P07 will still be making range trips with me, as it is a fantastic shooter..
