P-07 Squeak...

[Randomuser404]

Hey all,

First let me say that I absolutely love my new P-07. Its my first hammer gun and so far im loving it. Right now I only have two complaints:

1. The break is not at all what I expected. There isnt a definable wall and it feels very mushy. But I already have a hammer coming from CGW to fix that. No biggie.

Its the second issue that killing me, however minor it may seem

2. No matter what size backstrap I put on, I hear and feel the plastic "creaking" any and every time I pick up the gun. Its driving me crazy. Its not like I feel the polymer compressing, but I do feel it...settling? Again its a very very minor movement but I do feel it. Does anyone else have this issue? Ive never experience anything like this and have held just about every polymer gun there is

Its brand new from 2018, only about 300 rounds through it so far. But I have some Talon grips coming and am reluctant to put them on with this happening. What worries me is that it happens with any backstrap, meaning its probably a tolerance issue with the frame itself. Short of putting some loctite on there (which I really dont want to do) does anyone have a suggestions?

Thanks guys

EDIT: It is most definitely the backstraps mating with the frame that is causing the plastic creaking. Without the backstraps on I can grip the gun as hard as I like and...nothing. Same as the rest of my guns. Take the backstraps off on push them against a hard surface - nothing. But put a backstrap on the frame and it starts happening again. The closest thing I can liken it to is when you step on an old floor board - but with a more "plastic" sound. You know how you can feel the floorboard slightly give under your foot when it creaks - same issue here. Happens 90% of the time I grip the gun.

I'm going to try putting a shim underneath it and see if that helps. Does anyone have any other recommendations though? Obviously the best solution would be Loctite. But I dont want something so permanent. Is there a temporary sealant I could put on there and have the peace of mind that it could come off later - that would be ideal.

Nobody else notices this with their P-07?

Thanks gents

I am not sure about the back strap moment you are describing, some kind of shim comes to my mind as a possible fix, like a really thin plastic sheet from a binder. For the squeaking i would assume that a bit of oil of gun lube would take care of it.

While you have the pistol apart to install the new hammer some part polishing may be worth while. Here is a link to a guide on the subject. I just did this to my P-09 with noticeable results.

Here is a link to a great video on CZ P-Series hammer kit installation as well. I use this video every time i take mine apart.

I am interested to hear other forum members input on your questions.

Thanks for the video and links! This really is a great community . I'm just sure not sure if I have the necessary tools/trust in my abilities to do anything more than the hammer, lol. But thats a discussion for another day. Unfortunately, I have such a personality that I fixate on certain things and right now the plastic squeak is dead center of my mental crosshair.

I'm almost positive its the backstrap if at this point. I took some guerrilla tape and wrapped it as tight as I possibly could and, although it didnt go away completely, it got quieter and less noticeable. I actually thought of the shim idea too (didnt think of the binder sheet tho - great idea!) but I have a feeling that its probably not going to eliminate it entirely. Definitely worth a try though.

But i'm also curious if any other members have this issue. I tested all my other poly guns (including a P-10C) and couldnt get them to make the slightest noise or feel any 'shift'. Its just not a good feeling to feel/hear that movement anytime I bring up the gun - however small it may be.

Good info tok36. While my P-07 has taken a bit of a back seat since I bought a PCR and a P-01. But I saved the thread on tune ups so I can find it easy and downloaded the video. At some point I will be working on it and you saved me from searching for info I will be looking for.
Thanks !!!

So, you're saying that the backstrap is loose and has noticeable movement when installed?

[Randomuser404]

I wouldn't say it's 'loose'. It's not like I can wiggle it around or anything. It's really hard to describe without seeing it. I guess the best way would be to say that the tolerance feels likes it's off by a fraction of an inch.

Because of this, when I grabbed the gun it feels like a very slightly "click" and I heard the rubber squeak as it settles into the correct* position. Again it's a very minor movement but it is noricable

[cntrydawwwg]

Maybe pull the backstrap completely off, then see if the squeak is still there. That?ll rule out/in the back trap for sure.
   
    Then check both the backstrap and the frame for any small hint of plastic that may be hindering an exact fit.

   Sorry, only thing I can think of.

Is your issue possibly related to something done in this thread?

Very doubtful. I just didnt realize how poorly designed the 'flat' MS plug was and couldnt figure out why I was having such a hard time getting it in when others made it look so easy (they had the lanyard). But nothing I did would have damaged the frame or backstrap in anyway.

I like/use the lanyard loop.  If I fall off the kayak I'll still have the P07.

You wouldn't believe how many people (here and other forums) replace the lanyard loop with the flat spring cup because they say the lanyard loop hurts their hand when seating a magazine.

Then again, the lanyard loops on the P07/P09 are plastic.  Be aware that when you push upwards on the lanyard loop with something hard the lanyard loop may collapse.  Mine did on my P07.  I used a pick to "round" it back out.  I wouldn't make a habit out of changing on backstraps, hammer springs, etc.  Put what you want it in and shoot it.

[Randomuser404]

The backstraps wont be changed once the Talon grip goes on. Im just trying to figure out which I prefer before then. But nothing will be going on until I get this 'issue' resolved.

Its most definitely the backstraps (or a tolerance issue with the frame) causing the plastic squeak. Without the backstraps on I can grip the gun as hard as I like and...nothing. Same as the rest of my guns. But put a backstrap on and it starts happening again. The closest noise I can liken it to is when you step on an old floor board - but with a more "plastic" sound.

I?d try plumbers tape or a fluoride lubricant.  Or white grease.

[Winkel]

I would remove the retaining pin and slide the back strap on and off a couple dozen times.  Maybe it will wear in the mating surfaces and let it seat a little better. 

The other thing I'd try is find some wax like a clear crayon that comes with the old Easter egg coloring kits or some clear parafin.  Rub it well on all the mating surfaces between the backstrap and grip.  That should quiet the squeak.

I've already tried repeatedly taking them on and off again to no avail. However your 2nd suggestion is genius. I wonder if this would be a permanent fix or if it'll start to come back after a while? Id like to have a permanent fix before I put the Talon grip on. I'm not the most creative though so my brain just keeps looping back to glue lol. Suggestions like yours are why I love this forum! Wish there were more like it
